Digital Lithic Design CURATED AND DESIGNED BY RAFFAELLO GALIOTTO Advanced computerised engineering systems used to process stone offer incredible design possibilities.

By International Correspondent, Joe Simpson.

M

arble is an ancient material that has been used to write human history. For millennia man has, over and above the planet’s geological history inherent in the material itself, overwritten the peculiarities of stone to record culture, style and technique.

Today, the advanced computerised engineering systems used to process stone offer incredible design possibilities. The use of these tools, which may be considered as digital chisels, opens up new creative possibilities and could spark a farreaching re-appraisal of the creative use of stone.

The Digital Lithic Design exhibition, curated by Raffaello Galiotto at last year’s Marmomacc exhibition, sought to highlight – through the creation of a collection of 13 experimental works in marble – the potential of modern technology to transform stone through both conventional and digital design.

Machinery suppliers, software houses, tool producers, marble workers and quarries all took up the challenge to stretch their skills to the limit to highlight the new opportunities that this technology has to offer the industry.

The Digital Lithic Design exhibition formed part of the Italian 12

Stone Theatre project implemented

by Marmomacc, with support of the Ministry for Economic Development, the Italian Foreign Trade Agency and Confindustria Marmomacchine.

The event’s curator, Raffaello Galiotto, was born in Chiampo, Vicenza, in 1967. After studying Fine Arts in Venice, he founded his own design studio in 1993. He specialised in designing injection moulded plastic products, and his interest in manufacturing processes and technology later led him to experiment with new solutions and exhibition formats, especially in the field of marble and natural materials.

Galiotto has designed many products and collections with major companies in the industry, exploring the main features of stone, such as surface, gravity, translucency and colour. He currently teaches design at the University of Ferrara, while his projects have been widely published and exhibited in museums and international events.

The design pieces Acus This is a kind of armour sprinkled with pointed, slanted elements. This piece was produced using diamond disc cuts on a five-axis milling machine following precise 3D machining paths. The delicacy of the tips is preserved by the precision of the device that cuts and polishes the surfaces simultaneously to avoid the need for subsequent finishing operations.

Produced by Gruppo Tosco Marmi in Palissandro Oniciato.

Bicefalo Animal morphology provided the pretext to investigate and play with the numerical rules behind natural forms.

These are interpreted and translated in this piece using numerical controlled milling passes with a spherical tool. The automatic “graphics” of the machine, usually eliminated by manual polishing, are a key characteristic of this work.

Produced by Intermac in Bianco Carrara.

12 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

Cacto Marble polishing following 3D milling-cutting operations is usually performed by hand. This work experiments with the possibility of polishing the surface directly on the machine using dedicated tools and processing paths without any manual input. The complex and sinuous shape is closely related to that of the processing disc.

Produced by Omag, Henraux and Adi in Versilys.

Glomus The challenge faced by this project was the 3D milling of a complex surface with a continuous tool pass.

As in a ball of wool comprising a single, continuous thread, in this work the tool rests on the rough surface and takes a long, winding uninterrupted path to process the surface in one pass.

Produced by Helios Automazioni in Bronzetto chiaro di Apricena.

Lamellatum In this piece, enveloping, triangularsection spires have been created on a single marble block using a five-axis milling machine with diamond blade.

Each V-shaped passage was obtained by running a blade set at opposite angles on the same path twice. The resulting cut surface did not require any further sanding. The changing slope of the spires and their peculiar arrangement make the final object particularly dynamic and slightly asymmetric.

Produced by Donatoni in Bianco Lasa.

Leucon The singular character of this double spaced permeable wall lies in the difficulties of implementing the “undercut� area, i.e. the portions not normally accessible to processing tools. After developing the contoured double-sided surface, undercutting operations were performed using a special tool with a broader head which entered every single opening in a diagonal direction with a rotating movement that made it possible to process apparently inaccessible gaps.

Produced by Odone Angelo and Gruppo Tosco Marmi in Palissandro Reale.

Lisca In this, the conventional diamond cutting disc is re-interpreted with curved cutting paths distributed over an undulating surface. The disc makes two cuts over each path with opposite slants to produce V-shaped grooves that intersect with the rear surface to create a grooved network allowing light to pass through it with a strong 3D character.

Produced by Lithos Design in Travertine.

Litocorno Due to careful design and use of fiveaxis waterjet cutting technology, it was possible – starting from a workpiece of only 600mm in height – to develop a grooved, sinuous, twisted and hollow cone 6,000mm high comprising 100 superimposed monolithic rings.

Produced by Antolini in Bianco Lasa, Covelano “Macchia Vecchia”.

Micete This project was achieved using a diamond wire mounted like a bow on an articulated robotic arm.

The device’s rotation and tilting features made it possible to achieve an undulating, deformed-spiral cut.

The surface finish is achieved directly during the cutting without requiring subsequent manual finishing.

Produced by T&D Robotics in Bardiglio Imperiale.

Corteccia The long, perforated double-trumpet element of this piece was created by diamond wire cutting on a tenaxis device. The binary path of the cutting wire automatically generated the curved, cross-slotted surface and the perforation arising from internal cuts. The interior was created by inserting the wire into a previously drilled hole.

RESTOR ATION

The pursuit of the invisible patch: the gentle art of the mortar repair The recent ‘raising of the bar’ in the application of mortar repairs in heritage stone conservation works.

By Jasper Swann, Stonemasonry Consultant

I

n the September 2012 edition of Discovering Stone, I wrote about the benefits of using specialised repair mortars as an effective conservation measure for historic stonework, (‘Plastic Repair on Stone’, Discovering Stone Issue 22). The workability and excellent performance characteristics of the Lithomex and Jahn repair mortars, in particular, were at that time worthy of comment, and there has been a significant increase in the use of these mortars in recent years as masons discover how good they are to work with.

These mortars are now joined by the equally useful Plastalite stone repair mortar from Westox Building Products. A two-part acrylic modified cement based repair mortar, it is proving to be a versatile and effective product that also has the benefit of being locally manufactured.

Whilst my preference in repairing a stone is for installation of hairline stone indents where possible, there will sometimes be instances where this is impractical. In instances where the mouldings do not readily allow the introduction of a hairline joint, for example; where structural implications may arise; or where the geometry of a particular stone physically won’t allow the introduction of an indent, then the mortar repair, or ‘patch’ as most masons call it, still has an important place as a repair methodology. In repairing carvings and statuary, it is also an especially useful measure. And as masons have become more familiar with the various proprietary products

mentioned above, the quality of workmanship has improved significantly in recent years.

The art of patching It’s a particular kind of mason who enjoys the art of patching. It requires care, dedication, patience, a good eye for colour and, above all, a desire to achieve the almost unattainable goal: the invisible patch.

Former proponents of the epoxy repair – a largely Sydney-centric phenomenon – rested their case for preferring epoxy over mortarbased repairs on the ability to work with a pallet of colours and achieve an excellent visual match for the parent stone. And it was

Figure 1. A ‘colour chart’ of repair mortars.

One of a range developed by Traditional Restoration Company. (Photo: Jasper Swann)

20 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

undoubtedly the case that a good colour match, historically, was more readily achieved using the epoxy repairs than the mortar. Ultimately, however, the superior performance characteristics of the mortar repair has displaced the use of epoxybased stone repairs and, as masons have become better at working with it, some have been achieving outstanding results.

One of the great difficulties in colour-matching a mortar repair with the parent stone arises from the fact that the material is wet when applied and will dry to a significantly lighter colour. This requires the mason to possess predictive capabilities. How light or

dark will the mortar be once it has dried? Will it be a good match or, after much painstaking work and waiting for it to cure, will the patch need to be removed and re-applied?

Wetting down the parent stone can be of some assistance in predicting a good colour match of the wet repair mortar, but it’s a far from fail-safe tool. Every mason who has ever undertaken patching duties will have had multiple attempts at getting it right. It can be a deeply frustrating, not to mention economically unproductive, experience. And of course, experience is everything. And the masons most likely to produce patches of a high quality are those whose trials and errors have been numerous.

Some masons have developed a ‘colour chart’ to assist them, manufacturing multiple samples of fully cured repairs each with varying recorded degrees of pigment additives. Figure 1 shows an example, developed by the Traditional Restoration Company.

This is one of two such pallets they have created that they use as a guide to establishing likely

Figure 2. Mortar repairs to a coping springer gablet, executed by DRP Stonemasonry’s Victor Janecki. Can you spot the repairs? (Photo: Jasper Swann)

successful mixes. The initiative shows a commitment to quality of workmanship and is applauded.

Even a tool as developed as this, however, cannot replace experience in successfully selecting and blending colours.

On a recent conservation project that I was involved in, a gablet to a coping springer required repair of both its damaged roll moulding and its sunken face panel. The introduction of indents wasn’t considered practical. Figure 2 shows the stone on completion of the repairs, executed using Lithomex by DRP Stonemasonry’s Victor Janecki.

But can you see the repairs? I perhaps ought to feel a degree of embarrassment at confessing that I stood face-on to the stone and thought that the mason alongside me was joking when he extolled the quality of the patches. “We’re looking at the wrong stone,” I thought. “This one needs no repair at all.”

In one of those oddly discomforting moments, it became apparent that he wasn’t joking and that I was indeed looking at two substantial mortar repairs. They were barely visible, even when 22 viewed from two feet away.

Figure 3 reveals the location of the repairs. Care, dedication, patience, a good eye for colour and an abundance of experience, all had come together to deceive the critical eye. These are the moments of glory for the patcher! And these are the instances in which the bar is raised and all patchers should take note.

The invisible patch is only a short period of dedication away.

If only it were so easy. Much depends upon the overall visual appearance of the parent stone in the first place. Stonework with a richly developed patina of mottled and generally variable appearance is infinitely easier to patch ‘invisibly’ than largely unweathered stone of a uniform surface colour. With care, though, this too is achievable, as Figure 4 illustrates. Here, the astragal mould at the top of a column has been repaired using Lithomex of a homogenous colour. The result is particularly good.

On a significant Sydney church spire, a series of carved heads adorning pinnacles at the base had suffered extensive loss of their upper detail. The ravages of sun, wind, rain and salts had weathered the gothic heads away to the point of imminent loss.

Some may have been tempted to replace the heads with new carvings, and in some instances, this was indeed appropriate and new heads were carved. But my preference is always to retain as much original historic fabric as possible, and rarely is it more compelling to attempt to do so when historic carvings are at risk.

For unlike architectural mouldings, carvings are the individual and unique expressions of men. They are, if you like, the most tangible of architectural bridges to our ancestors.

The faces on these particular carved heads were wrought by men at the height of their trade, in 1850s Sydney, when stone was the quintessential local building material; when elegant university buildings, cathedrals, churches and a variety of other public buildings were rising fast in the still-young colony; when gas-lighters plied their evening trade; when the well-to-do took horse-drawn omnibus rides on Sunday afternoons; when children rolled hoops; when steamers docked from the Motherland carrying mail from home penned six months earlier by their loved ones. When some of their mates headed to the gold fields in pursuit of an easy fortune, these men – ­ who walked to work each day

carrying their fire-sharpened tools in a leather pouch under one arm and a doorstop of bread and cheese under the other – put their efforts instead into honest work. Using the skills that had, week-in, week-out, brought them the greatest of satisfaction – that gained though creative endeavour. They brought thoughtful, contemplative, even meditative faces to life from hunks of the local sandstone. Those faces, which looked out through increasingly fading eyes onto a very different 21st century life when I first observed them in 2013, could still be saved and preserved for future generations by the careful application of mortar repairs.

Figures 5 and 6 show one of these heads before and after repair. Note that no attempt has been made to guess at and replicate any of the original detail that may have existed in the upper part of the head. The intent is to preserve what remains of the original detail by minimising the further effects of weathering and thus arresting the mode of decay. It is the original detail, and its preservation, that is important.

The skill in achieving this outcome lies not only in the philosophical approach, but also in making the repair as invisible as possible. And

here the mason, HBS Group’s David Jakovich, has done an excellent job in blending his pallet of coloured mortars to good effect.

On the same project, a statue of Catholic Archbishop Polding, carved by the eminent French Benedictine monk and sculptor, Father Jean Gourbeillon, had long since suffered such severe fracturing as to precipitate the removal of his head and shoulders in an earlier program of make-safe works. The head was recovered from the parish priest’s office, where it had mournfully sat on the floor for some years, (Fig.7).

There was no sign, however, of the Archbishop’s shoulders.

With the head reinstated and secured with stainless steel rods, it remained only to re-form the shoulders and repair the associated localised cracking, (Figs.8 and 9). Here again, the skill of the experienced patcher produced an outstanding result.

Building a repair around a stainless steel armature and carefully blending various colours of Lithomex repair mortar, the mason has restored this statue to its original form and extended the life of this significant sculpture for another generation to 26 come.

The link to Fr Gourbeillon and the rich historical backdrop of his times has been preserved. It provides a good example of how statuary can be conserved in an era when it might too easily have been replaced. There is, in my view, too much to lose in replacing, rather than repairing, such significant elements as these.

The skilful use of mortar repairs is a particularly important conservation measure in the preservation of carvings and statuary.

Maintaining realistic expectations The experience being gained by masons using the latest materials is delivering increasingly impressive results. Pursuit of the ‘invisible patch’ must remain the Holy Grail for patchers. However, it is not easily achieved and this must be recognised by those responsible for quality assurance on any stone conservation project. The masons must always do their best. And, in moments that are particularly satisfying for all, their best will sometimes be exemplary. ● All photos by Jasper Swann 26 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

Limestone is extremely popular at the moment, the material is used in practically every element of our built environment. However, tiles must be carefully evaluated to define fitness for purpose. (Image courtesy of CDK Stone).

Stone in the built environment – a guide to specifying limestone tiles Limestone is in fashion – this can be seen in its ubiquitous use as a floor finish throughout shopping centres, homes and commercial buildings. Its popularity can be largely attributed to its versatility and variety.

By Jim Mann, Principal of Stone Initiatives and a director of the ASAA

imestone is a sedimentary rock. Every millimetre of sediment laid down has a slightly different composition and is converted into the stone we know under varying conditions over millions of years. The result of this prehistoric manufacturing process is that every slab of limestone is unique.

This exclusivity is one of the appealing aspects of natural stone, but with this variety comes challenges that, if not addressed, can turn into problems after installation.

Stone Initiatives has investigated limestone failures in a broad range of locations. Most of these failures are related to inappropriate installation practices or the use of stone that is not fit for its intended use. This article provides guidelines that can assist in the specification of limestone and is intended as a first step in ensuring

fitness for purpose when using limestone as a floor tile.

Whether installed in a domestic bathroom, a shopping centre or the lobby of a commercial building, the tiles should be evaluated for fitness for use based on the following four performance properties:

Durability All tiles are to some degree exposed to moisture. Tiles installed in a wet area such as a bathroom are subjected to regular wetting during use, while dry-area tiles are likely to become wet during the cleaning process. In both cases, the tiles must have adequate durability to withstand wetting and drying cycles as well as exposure to cleaning chemicals.

Wet-dry cycling can result in deterioration of the surface finish of the tiles, and this most commonly

presents as spalling. This spalling is usually due to detachment of flakes of stone along features called stylolites, which appear as fine, zig-zagging veins on the surface of the tile.

Stylolites develop at pressuredissolution boundaries, where insoluble minerals within the stone (e.g. clay) accumulate. The development of these planar features usually results in the formation of clay-lined veins and micro-porosity; as a result, there is a localised increase in water absorption capacity. This increase in water absorption can cause a reaction between the clay and moisture, the consequence of which can be a reduction in strength and durability.

Load-bearing capacity For a tile to be fit for use, it must be able to withstand relevant service loads.

www.discoveringstonemagazine.com.au | DISCOVERING STONE #28 | 27

A RCHIT ECT U R E & SP ECIFICATION 27

Imposed loads are usually confined to pedestrian traffic but may also include light traffic such as trollies or wet-vac scrubbers. While a limestone may be inherently strong, the load-bearing capacity of a tile may be compromised by the presence of stylolites that can present a zone of weakness.

Stain resistance Water-absorption capacity is the most relevant physical property for determination of stain resistance. In practice it is a complex relationship between porosity, chemical composition and appearance.

All limestone is composed predominantly of calcium carbonate and is therefore sensitive to etching from acidic materials such as wine or soft drinks. The tonality, surface finish and figuring also have an effect on the apparent stain resistance of a tile.

Wear resistance Limestone is a relatively soft stone and this can be an issue in high-traffic areas. Abrasion of the surface may change the surface texture, resulting in a change in appearance and a reduction in slip resistance.

Specification guidelines The key performance indicators for limestone tiles are considered to be: • water absorption • bulk specific gravity • modulus of rupture (3-point bending strength) • abrasion resistance • durability The table pictured (Table 1.) sets out properties recommended for limestone tiles that are to be installed internally on an adhesive bed. The recommendations in the table were developed by Stone Initiatives based on the requirements for high-density

limestone set out in ASTM C568M-15, which covers limestone for “general building and structural purposes”.

Stone Initiatives further developed the ASTM specification values after its investigations revealed that, in order for limestone to be fit for use as a floor tile, it should meet performance requirements that are more stringent than those stated in the ASTM specification.

Bulk specific gravity (commonly referred to as density) is a fundamental key performance indicator. A higher density usually corresponds with improved strength and durability as 30

well as superior resistance to wear and staining. Limestone tiles that perform best in service usually comply with the high-density requirements of the ASTM specification. While density does not generally vary greatly within a deposit, a significant variation may suggest a stone with unreliable properties.

The most significant variation from the ASTM specification is related to water absorption. Stone Initiatives has found that limestone tiles that have performed successfully on site usually have a water absorption level of less than 1.0%. Consistency of individual results is equally important, as a broad variation in individual results is likely to be a sign of open stylolites, which present a risk to durability and strength.

Consistency in results is also important when it comes to modulus of rupture. A stone with a high mean strength can be compromised by occasional low individual results ‘hidden’ within the average. These low results may be an indication of the presence of unstable stylolites or unfilled veins. It is important to note that compliance with the modulus

of rupture requirement does not necessarily mean that a particular tile size is able to withstand the flexural loads that may be imposed upon it on site. As well as inherent strength, the load-bearing capacity of a tile also depends on its length-to-width ratio and thickness. The greater the lengthto-width ratio, the greater the flexural stresses applied to the tile (square tiles are less prone to flexural overload).

Thickness is also important as it has an exponential effect on the flexural loadbearing capacity of the tile; doubling the thickness increases the breaking load fourfold – every millimetre of thickness counts.

The standard method for determining the durability of dimension stone is through the resistance to salt attack test. This test involves cyclic immersion in a salt solution followed by oven-drying and gives a good indication of the durability of a tile in a wet environment.

Although the test results are expressed as a weight-loss percentage, remarks on the appearance of the specimens after testing also give an indication of the mode of any decay that may occur – whether it is loss of gloss, spalling,

30 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

cracking or pitting. As for the other properties discussed previously, it is important to review the variability in the individual results, as this will assist in determining if any large flakes of stone are lost through spalling.

As for density, abrasion resistance does not generally vary greatly within a deposit, although any significant variation within individual results may suggest a stone with unreliable properties.

All physical properties are interrelated, so it is important that all results are reviewed together. This will provide a holistic view of the limestone’s likely performance. The guidelines for selection discussed above should be considered only as one tool in your arsenal. To ensure adequate performance of your limestone tiles it is vital that careful attention is given to the design of the installation method, including the type of adhesive and grouts used, the location, type and spacing of expansion joints and the selection of a suitable sealer. Once these elements have been considered, you are well on the way to producing a flawless floor finish. ●

Australian imports of natural stone increase again in 2015 The value of natural stone imported into Australia has risen again for the third consecutive year.

he value of natural stone imported into Australia has risen again for the third consecutive year. The Australian Bureau of Statistics (ABS) reported the total value for 2015 reached A$252,735,695.90, an increase of 19.2 percent over the 2014 figure, which itself was 21.2 percent increase over the 2013 figure, which was 7.8 percent up on 2012. The successive rises over the last three calendar years were the biggest increases since 2008.

The total value figure as recorded

by Australian Customs includes all international Harmonized Commodity Description and Coding System (HS) classifications describing natural stone in either

a raw, crude or finished form. The 10-digit level of the classification system is also known as the Harmonized Tariff Item Statistical Code (HTISC), which describes stone in broad categories such as ‘Crude or Roughly Trimmed’ stone, Pebbles and Gravel (codes beginning with 25) as well as the biggest grouping, ‘Worked’ stone (codes beginning with 68), then breaks them down into common types. (A table of classification descriptions can be found later in the article in Figure 6.)

Natural stone imported as ‘Crude or Roughly Trimmed’, meaning stone in a roughly quarried format before working or processing into

finished articles ready for consumer use, decreased by 9.7 percent. While ‘Crude or Roughly Trimmed’ stone only accounted for 2.4 percent of the total value of stone imports, the much higher value ‘Worked’ or processed categories (for example into tiles or slabs) rose by 20.1 percent over the previous year.

Part of the increase in value was due to the deterioration in foreign exchange value of the Australian dollar against major trading currencies such as the Euro and US Dollar. Figure 1. illustrates the declining trend in the average monthly foreign exchange value of the Australian dollar (AUD) over the last two years.

Figure 2a. graphically illustrates the regular increasing trend in the value of imports of ‘worked’ natural stone over the last five years by (HTISC) codes. The category descriptions can be found in Figure 6. The more variable annual import value for the different categories of raw or crudely finished stone can be seen in Figure 2b.

Figure 3. displays the 2015 total value of natural stone imports across all categories showing the country of origin and the state listed as the final import destination. The largest value of imports originated in China in 2015 at 44.2 percent of the total import value. Stone from Turkey made up 16.7 percent of the total value, Italy made up 13.9 percent, India 7.4 percent, Indonesia 2.4 percent, United Kingdom 2.0 percent, Spain 1.8 percent and Greece 1.3 percent.

The majority of natural stone imports in 2015 were destined for New South Wales (39 percent of the total value) followed by Victoria (33.1 percent). Queensland was the third largest destination state at 12.6 percent followed by Western Australia at 11.5 percent.

New South Wales received 24 percent, Queensland represented 17 percent and Western Australia six percent. Raw or crudely finished stone is mainly imported for further processing in Australia with import volume and value being heavily influenced by commercial projects.

A list of HTISC code descriptions relating to natural stone is shown in Figure 6. Natural stone can be categorised into three basic geological classifications by the manner in which they were formed: sedimentary, metamorphic and igneous. Additionally, stones within each geological categorisation can be described as either calcareous or siliceous. Calcareous stone is composed mainly of calcium carbonate, a chemical compound normally found in natural stone, shells or pearls. Siliceous stone is composed primarily of silicates such as quartz, feldspar, mica, etc. Calcareous stones are generally more susceptible to acids than siliceous stones. Calcareous stones that are sedimentary include: limestone, travertine and onyx. Calcareous stones that are metamorphic (or have been changed) include marble and serpentine. Siliceous stones that are sedimentary are generally sandstone. Siliceous stones that are metamorphic are generally slate, quartzite and soapstone. Granite is an igneous siliceous stone. Basalt has a generally lower silica content than granite but is also igneous. ●

International Award Architecture in Stone Now in its XIV edition, the International Award Architecture in Stone, a biennial prize for architectural works in natural stone, was one of the main features at last year’s Marmomacc.

By International Correspondent, Joe Simpson.

N

ow in its XIV edition, the International Award Architecture in Stone, a biennial prize for architectural works in natural stone, was one of the main features at last year’s Marmomacc.

Curated by architect Vincenzo Pavan, the award spans a huge panorama of international stone architecture, from large scale urban developments to residential sites, and includes both new build and restoration projects.

All the projects on the shortlist interpret the world of stone through new techniques and languages while displaying due respect for the existing landscape.

This edition of the awards also included a special “in memoriam”

award dedicated to an artist of the past: Adalberto Libera.

The 2015 jury – comprising Francesco Dal Co (Department of Architecture, University of Venice), Juan José Lahuerta (ETSAB, Barcelona, Spain), Werner Oechslin (ETH Zurich, Switzerland), Cino Zucchi (Department of Architecture, University of Milan), and Vincenzo Pavan (Department of Architecture, University of Ferrara) – assessed a total of 31 architectural projects that had all been completed over the past two to three years in 18 different countries.

After thorough analysis and extensive discussion, a shortlist of projects was selected for their architectural quality, expressive use of stone materials and quality of design; the jury considering them to represent a clear and significant

panorama of the best achievements on an international scale.

The strategy of this project was determined by the morphology of the landscape of which the building becomes an extension. A sequence of rustic stone walls and slab steps, which link the construction with the lawn, mediate descent into underground spaces that house the prayer rooms, conceived as caverns.

With the exception of the minaret, which rises as a landmark and was conceived as a parallelepiped (a prism whose faces are all parallelograms), only low horizontal volumes of the complex come to the surface.

The Jumex Museum by David Chipperfield Architects, with a volume characterised by light stacked overhangs and an unmistakable shed roof, confronts the urban development of Mexico City with stereometry of great iconic power.

The large slabs of the Xalapa travertine façade emphasise the stark contrast between the openness of the floor plan at the ground floor level, the panoramic loggia on the first floor and the compactness of the upper gallery floors. The interiors use plaster, glass, concrete and stone – with a multicoloured marble bookshop floor by the artist Martin Creed – to modulate the

Tower buildings in Hagenholzstraße, Zurich, Switzerland, 2013 The Hagenholzstrasse group of buildings by Max Dudler, among the various projects and achievements for the Zurich Metro, West-Zürich and North-Zürich zones, is one the very few interventions that, thanks to the shape of the urban typology, is a clear expression of urban planning.

It is as if the archetypal form of the stone, as cut blocks and geometric cubes, determined the architecture in a linear and direct composition that runs through the smallest details right up to the complete form. The quality of the Hagenholzstrasse complex is to be found in this use of elementary forms that are in perfect harmony with the intrinsic character of the material.

This complex, located close to a beautiful portions of the Northern Irish coast characterised by columnar basalt concretions, is brilliantly placed in the landscape.

The sharp lines of the floor plan and the inclined planes of the roofs are made meaningful by the designers’ use of tall stone slabs of different sizes in the elevations. Their dark surfaces punctuate the rhythmic alternation of empty and full spaces and give significance to the whole envelope emerging from the soil.

Austral black granite –

Australia’s first Ecolabelled natural stone Words by Anthony Stock Left and below: Locally quarried Austral Black granite by Melocco Stone features prominently in our built environment. The product recently gained a GECA ecolabel. Here it can be seen as external paving using exfoliated Austral Black granite in Pitt Street Mall, Sydney. Ecolabelled Austral Black granite is available in a variety of finishes.

Significantly the material has a low water absorption rate of 0.6 per cent, which compares favourably to the densest porcelain products.

Gaining an Ecolabel – the benefits

B

ack in 2008, the Australian Stone Advisory Association (ASAA) contacted Good Environmental Choice Australia (GECA) to encourage the development of a Hard Surface Standard, which would form part of their Australian Ecolabel Programme.

The Australian Tile Council became involved and a committee was formed to develop the Standard: eventually GECA 40-2008 was introduced. The Standard covers a variety of hard surface materials, including natural stone.

Local producers and importers/ wholesalers of high quality materials can seek accreditation for their products. In recognition of the importance of this development ASAA introduced a set of guidelines that members can submit to GECA when they seek to gain accreditation for their materials.

While a growing number of European manufacturers of ceramic tiles have gained an Ecolabel for various products, the stone sector has been less enthusiastic, possibly

because manufacturers believe that, in many instances, natural stone is the only material that specifiers will nominate in certain situations, based on the product’s history and performance.

Nevertheless, nowadays a great many more alternative surface finishes are available to architects, so any advantage that can be gained by achieving accreditation for a high quality natural stone product must be worthy of consideration.

Melocco Stone has traded in Australia for over 100 years.

Austral Black granite quarried in South Australia is one of their prime products and has been used in numerous commercial and residential projects. The fine/ medium grained black stone features subtle light flares and delicate white veining.

Austral Black can be used in a variety of internal and external locations. Melocco produce the stone in a variety of finishes including polished, exfoliated, honed and gang-sawn, as slabs, tiles and panels.

Melocco Stone’s Managing Director, Ian Lamble decided that gaining GECA’s endorsement for Austral Black granite would be in the company’s long term interests. In recent times the Green Building Council of Australia (GBCA) has formally recognised GECA Standard number 40, which basically means that any accredited natural stone (or ceramic tile) can achieve maximum points in Green Building calculators.

Melocco has made a bold move, which local architects seeking to use high quality black granite should recognise and appreciate. ●

A spectrum of hues and tonal depths New Melbourne office bears testimony to the enduring practical qualities and aesthetic appeal of Fibonacci Stone’s terrazzo tiles.

E

quip Super, a Melbournebased superannuation company, wished to relocate and re-invigorate its workplace on a single floor with open offices to enhance transparency and teamwork. They engaged Melbournebased architecture and design studio, Antarctica, to assist in formulating a brief, assess possible new locations and design the integrated fit out. The end result is that Equip Super now occupies an open, modern space that promotes wellbeing and collaboration.

The new office occupies a 900 m2 floor of a 1950s multi-storey building in Melbourne’s CBD. It

has a long, narrow plan divided into three zones. The first zone comprises the reception, foyer and breakout areas. It is characterised by beautiful natural light, a lush hanging garden and a harmonious mix of materials, including timber and Fibonacci Stone’s terrazzo tiles.

Fibonacci’s Earth and Arctic Ice terrazzo tiles were chosen for the project. Earth features a spectrum of blue-brown tones that range from pale powder blues through to dark matt browns. The blend creates a warm, natural tonal palette that complements the new office environment.

42 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

The Arctic Ice tiles also contribute to the ambience of the space. With accents of pale grey and cool blue, they are suited to wide range of neutral, cool interior schemes.

“Flooring is a long-term decision, so it’s important to select a flooring colour that will support the ongoing evolution of your space. With each Fibonacci Stone terrazzo tile colourway encompassing a spectrum of hues and tonal depths, the aesthetic quality of each colour composition is perfectly homogenous, allowing the floor to seamlessly adapt to refreshed interior colour schemes and new fittings throughout its long-term life cycle,” said Michael Karakolis, Director, Fibonacci Stone.

The new Equip Super office includes a second zone with private meeting pods and offices. There is also an undulating storage spine that acts as a landscape and acoustic buffer from the third zone, which comprises south-facing open work areas. The workplace features a generous amount of greenery and open spaces to encourage a sense of well being.

Fibonacci Stone’s Terrazzo Tiles suit for both residential and commercial flooring applications as they possess a high slip resistance, require minimal ongoing maintenance and have a lifespan of over 30 years. They are manufactured from a blend of natural materials including mineral aggregates and pigments. Tonal variation due to use of these natural materials is considered an inherent characteristic of Fibonacci Stone’s terrazzo tiles.

Completely homogeneous, the tiles can be re-polished in-situ years following installation bringing the surface back to near new finish and can also be profiled to create edging if required.

Produced in a honed finish as standard, Fibonacci Stone’s terrazzo tiles are tested using Wet Pendulum and Wet Barefoot tests and meet the minimum classification requirements for most domestic and commercial applications. Finishes can be modified to achieve higher classifications if required.

Standard tile formats are 600 by 600 by 21mm, 400 by 400 by 15mm and 400 by 600 by 18mm formats.

Claimed to be the only terrazzo tile supplier to achieve a 100% Green Star rating, under the Green Star “Fit-Out Calculator” by the Green Building Council of Australia MAT-4 Concrete Credit, Fibonacci Stone’s terrazzo also provides a flooring solution that not only answers a wide range of aesthetic and budget requirements but also provides an ethical and environmental flooring solution for all interior situations.

Other green attributes include an accredited manufacturing process, high recycled content, and the Fibonacci Stone Stewardship Contract to disassemble the floor and arrange for it to be recycled at end of life. Achieving the lowest water cement ratio in its category, Fibonacci Stone terrazzo tiles also contribute to Green Building credits.

“Strength and hardwearing durability are important attributes in a hard surface floor. Designed for longevity, Fibonacci Stone terrazzo tiles will last up to 30 years, meaning you won’t have to replace your floors for years to come. Fibonacci Stone terrazzo tiles can also be polished in-situ at any time, meaning scratches can be easily repaired, and flooring rejuvenated years after installation,” said Michael Karakolis.

“Produced using a high percentage of natural aggregates and low percentage of inorganic binder, consistently distributed throughout the tile, Fibonacci Stone terrazzo tiles are exceptionally strong, durable and flexible. Fibonacci Stone also utilises UV resistant pigment oxides to ensure colour consistency is not compromised.”

Equip Super’s new office certainly bears eloquent testimony to the enduring practical qualities and aesthetic appeal of this long-established, versatile material. ●

An introduction to CNC

By Machinery Editor, Philip Ashley

A

lthough it appears that CNC manufacturing popped up yesterday, in fact it’s been over 60 years in the making.

If you work with stone or other similar materials, CNC processing can be an extremely versatile method of producing benchtops in granite and marble but also for a range of other products such as cladding, tiling, shower bases and fire-place surrounds.

CNC machines are still a large investment for most companies with $350,000 to $500,000 being a ball-park figure. They do, however, offer the potential for significant improvements in output and quality that far outweigh the initial cost.

NC control came about as a result of the American military aircraft industry. At the end of the Second World War it was apparent that faster jet aircraft required more complex and demanding parts. Conventional means of manufacturing were falling short of the required tolerances and a faster, more accurate method of parts manufacture was needed. The movie “The right stuff ” chronicles the race to break the sound barrier and

conquer space and it is within this time frame that the history of CNC is set.

During the late 1940s John Parsons was working on a system where punched cards containing position data controlled a machine tool. The idea was to machine flat templates to check the contour of helicopter blades. Parsons submitted his idea to the US Air Force in 1948 and was awarded a development contract with the University of Massachusetts (MIT) Servo Mechanisms laboratory.

During the next three years a conventional milling machine was fitted with positioning servomotors for three axes (or movements) known as X, Y and Z and the first NC routing machine was born.

The machine demonstrated in 1952 looked very similar to a modern-day single spindle CNC router. Different were the banks of computer consoles needed to drive the servomotors, almost equal in area to the machine itself. All this was driven from a punched paper tape, and became known as numerical control, or NC. Numerical control

46 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

is where machine codes are used to “drive” the machine. There are codes to start and stop motors; move the cutter-head left, right, up and down; and other codes for feed speeds and spindle RPM, etcetera.

Development in the woodworking industries began in the mid 1960s when the Ekstrom Carlson Company offered the first NC router in the USA. The Japanese Heian company developed its first NC router in 1968 and in 1969 Shoda claimed the first circular-cutting NC router. Early machines of the NC type relied solely on a punched tape. The paper tape had holes punched into it that the machine controller read as code. No calculations or modifications were possible on the computer and a new tape would be made even if only one code was changed.

Computer numerical control (CNC) was not to follow until IBM developed the personal computer.

The American Thermwood Company claims the first CNC machine, based on the Intel 8080 chip. Unlike NC, a CNC machine is able to perform some calculations

such as acceleration and deceleration of the axes, and offer modification of programs at the machine control. These early CNC routers used G-code as a programming language, and this may still be used today on all CNC machines processing metal, wood, stone and even glass. In the stone industry, the first CNC machine is claimed by the Italian CMS brand in 1985.

In the early 1980s the first pointto-point machines appeared. These were primarily drilling machines and were developed from engineering machines of the same type where the workhead rapidly moved from point to point to insert pre-programmed drilling patterns. A sawblade was often added but there was no means of simultaneous movement of the three axes and therefore no possibility of a shaping option. From the late 1980s, profiling machines for wood and stone have been rapidly accepted in Australian industry where we use more CNC machines per capita than most other countries.

These machines originally used a proprietary controller and software but now all CNC machines accept code from CAD software programs.

The CAD drawing is converted into code with a post-processor written just for that machine.

The most common stone cutting machine in Australia is still 3-axis with a few 4-axis machines for specialist manufacturers. The main suppliers of CNC stone equipment are CDK, Breton and Biesse (Intermac).

“Your new CNC machine will have a flat table, usually of aluminium, and on which are placed ‘pods’ or supports to hold your stone workpiece.

The pod raises the workpiece up to 100mm above the table to allow your cutting and shaping tools to cut through the part."

Recently, cheaper machines have been developed and software is getting much easier to use so 5-axis may be just around the corner.

Your new CNC machine will have a flat table, usually of aluminium, and on which are placed ‘pods’ or supports to hold your stone workpiece. The pod raises the workpiece up to 100mm above the table to allow your cutting and shaping tools to cut through the part, as in the case of a kitchen top, or shape the outside edge with shaping (routing) tools. The pods may be positioned with the help of a laser that points to where the stops and pods need to be placed. The laser may also be able to show exactly where the cuts are to be made and this usually requires a laser mounted above the machine.

The cutting tools will be located in a tool-holder and this may be placed at the back or side of the machine table. You may also be offered a tool changer that travels with the main spindle and this saves a great deal of time. Every time a new profile is needed the machine will drop the

existing tool and replace it with a new profile.

The more you spend, the more tool change positions you will get.

Depending on the type of work you do, you may need tools for drilling, engraving, milling, grinding, carving, polishing, sawing and profiling.

Stone is cut with a large diameter diamond tipped blade and the edge finished with diamond and abrasive polish tooling. Feed speeds for stone are in the order of three metres a minute using a bridge saw and up to five metres a minute for edge profiling.

Diamond tools can be expensive but they last a long time, especially in homogenous materials.

Today, the software is provided on a personal computer and is very advanced but easy to use. You will need to draw the shapes to be produced and then indicate the direction of the tool travel and on which side of the drawn line the tool should be. The drawing is then converted to the code the machine understands.

You can import drawings from other software programs if the code is in a generic format. Generic formats include DXF for 2D shapes and STL for 3D shapes. A feature of modern CNC machines is the ability for “parametric” programs. A parametric program could have a sink cut-out in the centre of a bench top and if the bench top length is changed, the sink remains in the centre of the top.

With CNC, anything is possible right up to and including Michelangelo’s statue of David. CNC technology gives you the ability to provide accurate, repeatable products and custom, niche market goods.

If you want to remain a serious player in the stone industry, CNC could be the way to go. ●

Quality stone benches improves cabinet making efficiency Making their own engineered stone bench tops gives Precision Cabinet Makers total control over their cabinet making manufacturing process.

“This greatly increases our efficiency and the overall quality of our cabinet making and kitchen installation.

This reality is clearly reinforced by customer feedback and satisfaction,” said Precision’s managing director Matt Schoof.

Precision Cabinet Makers is one of the larger companies in West Australia’s cabinet making industry. With a 30 year history this family-owned business is now widely regarded for whole-ofhouse, particularly kitchen cabinet making. Producing up to 50 kitchens a week, the company is well-known across West Australia for supplying custom-made kitchens, vanity cabinets, walk-in robe cabinets and other types

of household cabinetry, together with accompanying stone bench tops.

“The ability to manufacture our own bench tops is a central, critical part of the company’s cabinet manufacturing.

Yes: we can absolutely guarantee design flexibility, quality manufacturing, plus installation timings,” said Matt.

The bulk of the bench tops manufactured by Precision Cabinet Makers are used for their own house fit-outs but some other cabinet makers in West Australia are also supplied.

Equipping and commissioning Precision Cabinet Makers’ stone bench top manufacturing facility was a collaborative venture between the company and Intermac. The central

Also part of Precision Cabinet Makers’ stone bench top manufacturing facility is a 4-axis bridge saw that does the initial cutting of stone slabs.

Also vitally important to the overall efficiency of the manufacturing process is a sophisticated water recycling plant.

With the Intermac Master 33CT, bridge saw and polishing functions using up to 200 litres of water a minute, water processing and recycling is a critical part of the business, both commercially and environmentally.

Intermac brand sales manager Craig Haidley remarks that Intermac is very proud of its relationship with such an outstanding West Australian cabinet making enterprise as Precision Cabinet Makers.

“They are one of our nationally stand-out partners and we continue to be very enthusiastic about supporting their manufacturing excellence and business success,” he said. ●

Cutting systems for the evolving stone industry

TECHNI Waterjet Cutters are the preferred cutting tool for stone fabricators using modern stones such as Dekton, Neolith, or Maximum Fiandre.

These man made stones are extremely hard and abrasive, and can therefore be very difficult to cut with traditional cutting tools such as saws, drills, and milling cutters. However, a TECHNI waterjet cutter can easily cut any shape, including accurately mitred edges ready for assembly, at speeds up to 1000mm/min.

echni Waterjet Cutters are a preferred cutting tool for stone fabricators using modern stones such as Dekton, Neolith, or Maximum Fiandre.

These man made stones are extremely hard and abrasive and can, therefore, be very difficult to cut with traditional cutting tools such as saws, drills, and milling cutters.

However, a Techni waterjet cutter can easily cut any shape, including accurately mitred edges ready for assembly, at speeds up to 1000mm/min.

With the Intec 713-G2 and Quantum NXT electric servo pump, major stone fabricators like Pacific Stone, Nasa Stone, Heritage Stone and Doric Marble now have the ability to load one sheet of stone, cut all the panels including the side panels, with mitred cuts. With the integration of the PAC 60 5-axis cutting head on the waterjet, it provides the capabilities to cut a +/- 60 degree bevel with continuous rotation and account for taper compensation.

“I’ve seen the waterjet cutting process growing in the ever evolving stone industry: however, it wasn’t until I owned my very own Techni Waterjet cutting system that I truly appreciated the benefits of cutting stone with waterjet. I am amazed at the ability of the 5-axis cutting head to prepare mitred components for both natural stone as well as the very hard man made stones such as Dekton,” said Daniel of Pacific Stone.

Techni Waterjet focuses on developing waterjet machines and cutting technologies to give its customers a competitive advantage. By finding innovative solutions to overcome the challenges of waterjet cutting, Techni provides waterjet cutters that generate the highest return on investment within the industry.

Techni is one of the world’s leading manufacturers of profile waterjet cutting systems. It is the only company in the world that can offer complete water jet cutter solutions utilising its own patented in house technologies for everything from the revolutionary electric servo waterjet pump to the 5-axis cutting head.

Techni is an Australian owned and made company, which has been operating for more than 27 years and has an installation base of almost 1000 waterjet machines or water cut systems spread across six continents and some 25 countries. It has dedicated sales and services offices in the USA, Australia, Asia and Europe, with spare parts, sales and service support throughout the world. ●

Unimac announces partnership

U

nimac has anounced its partnership with CMS Brembana and Montresor.

The agreement was set up in 2014, proceeding the Marmomac Verona expo.

Steve Hoareau, founder of Unimac Machinery back in 2010, with 30 years experience in the stone / wood industry, decided on CMS for all the company’s CNC machining solutions and Montresor for edge polishing and finishing.

Steve has brought into the business, as an equal partner, Pierre Sullivan, who heads up the after sales service department. Pierre has a vast knowledge in this type of equipment and has been involved in this market ever since arriving in Australia from Ireland back in 2005.

Pierre and other Unimac technicians have been factory trained to allow for a high level of knowledge and expertise for the Austarlian market.

“CMS Brembana is the perfect company for us as they offer the full range of equipment for the processing of granite, marble, ceramic and engineered stone,” said Steve Hoareau. “And, as their acronym suggests, CMS (custom

Steve Hoareau

Pierre Sullivan

machine specialist) provides us with many machine options to provide our customers with the correct solution.”

Saw range: CMS sizing solutions range from 3/4/5 axis saws with vacuum manipulator to fully automatic sizing lines and combination saw and waterjet.

The variety of solutions suits the continuing demand for flexability from our customers, with the humble bridge saw being replaced by high technology sizing systems.

CNC working centres: again, CMS offers 3/4/5 and 6 interpolating axis CNC working centres with a variety of table sizes and working heights designed to work ultra thick slabs, which allows them to cater for fabrication from counter top manufacturing to monumental fabrication.

Waterjets: offering three and five axis solutions, this style of machinery has picked up momentum due to the push into ceramic/porcelain slabs. The industry has found using waterjet technology for the machining of this type of material has many benefits over the use of saws or CNC working centres.

52 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

Montresor: completes Unimac’s range of equipment for the fabrication of components as they offer machines for edge polishing from straight flat edges, beveling, pencil round to a variety of edge profiles. as well as edge polishing.

Montresor offers a unquie machine, the Viva220 that ‘V’ grooves the components to allow for perfect mitre joints. This takes away the need for mitring on a bridge saw or other straight line mitre machines.

“These two brands complete our machine requirement for the fabrication of stone,” said Steve. “The best thing that ties it all together is the software offered on the CMS Brembana range uses the same platform from a CNC saw to CNC working centre to waterjet machine.

This creates a more user friendly enviroment within the office design departments.

“Also, with these brands now available, it allows Unimac Machinery to offer complete factory solutions. To complement these brands, we have collaborated with Fraccaroli N Balzan, specialists in water filtration systems, and Dal Forno vacuum loading systems.” ●

CMS Brembanaâ&#x20AC;&#x2122;s technological commitment generates machining centres for top quality results in marble, granite, natural and composite stone creations. Outstanding systems, designed to bring added value in multifarious industrial fields. CMS is an industrial partner rich in solutions aimed at engineering and process optimization.

SE AL ER SEL EC TI ON G UI D E

Sealer selection guide 2016 Many of the calls the Australian Stone Advisory Association (ASAA) receives relate to problems that arise after the stone has been installed.

A considerable proportion of those calls relate to sealing, cleaning and maintenance.

Discovering Stone decided to produce a basic Sealer Selection Guide in response to requests by contributors and readers of the magazine. We have attempted to make the guide as relevant as possible by focusing on use of three popular products, in specific locations and asking leading suppliers to nominate appropriate sealers. However, our guide can only provide readers with basic information. There will always be variables which have to be taken into consideration.

While our guide cannot possibly address every possible situation or environment it does provide a valuable reference point and an insight into the available products from some of our leading suppliers.

More than 50 companies in Australia are actively engaged in producing or distributing sealers for natural stone.

This guide largely features materials

that have been tried and tested in the marketplace.

Understanding the limitations of sealers is also important. Sealers are designed to improve the natural stain resistance properties of stone â&#x20AC;&#x201C; they will not provide 100 per cent protection against all stains in all situations.

As an example, an impregnating sealer will not prevent marble or limestone being etched by acidic solutions such as wine or soft drinks; impregnating sealers are designed to reduce the absorption of stains and cannot provide complete protection to the exposed surface.

Surface sealers (such as acrylics and polyurethanes) provide excellent surface protection by forming an impermeable barrier. The drawback of this feature is that any moisture below the sealed layer cannot escape and peeling of the coating may follow.

Participating companies can provide project specific advice, some also recommend approved applicators. We urge readers to seek precise advice before commencing the installation process.

AUSTRALIAN STONE - BEST COMMERCIAL PROJECT PROJECT: Barangaroo South – Commercial Skyscrapers Towers 1, 2 & 3, Sydney, NSW LEAD ARCHITECT: Rogers Stirk Harbour & Partners Australia (RSHP) MAIN CONTRACTOR: Lend Lease STONE SUPPLY: Cairns Marble & Granite STONE INSTALLATION: Deemah Stone Pty Ltd STONE DESCRIPTION: Bianca Mist Marble Podium Floor Borders & Planters

Barangaroo – one element of a massive project

B

arangaroo, an inner city suburb of Sydney, is located on the north western edge of the CBD, at the southern end of the Sydney Harbour Bridge.

The area is part of the City of Sydney and was once owned by the Cadigal people, who hunted and fished around the shoreline.

The suburb now known as Barangaroo was initially called Millers Point. In the 1820s, European settlers began building houses in the area and a wharf was established. Direct routes to Millers Point eventually encouraged the development of the East Darling Harbour.

An outbreak of bubonic plague in 1900 caused alarm at the docks.

The Great Depression provided East Darling Harbour and the adjacent dock areas with a poignant nickname

62 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

– The Hungry Mile, which related to the crowds of workers who trudged around the wharves seeking work.

Today, the Barangaroo area is undergoing a massive redevelopment, which commenced in 2012 and is expected to be completed in 2023.

Natural stone, much of it Australian, features in abundance.

Sandstone, Sydney’s bedrock stone is present in the form of 10,000 blocks, which were used in the creation of a striking headland park located on the city’s doorstep. Other elements of the Barangaroo project will feature in future editions of Discovering Stone.

We anticipate that the next edition will contain a major feature on the project.

This entry highlights use of Cairns Marble Bianca Mist marble used in the three towers, which are currently under construction. The towers will incorporate retail outlets on the Podium levels, where most of the marble is installed. The towers will comprise apartments, retail outlets, public spaces and a hotel. The towers are named International Towers, Sydney.

To date almost 500 square metres of Bianca Mist marble have been installed by Deemah Stone Pty Ltd.

AUSTRALIAN STONE - BEST CIVIC PROJECT PROJECT: ANZAC Memorial Walk, Emu Park, Queensland ARCHITECT: Anderson & Associates PROJECT MANAGER: N G Gardner & Associates STONE SUPPLY: Capricorn Sandstone STONE DESCRIPTION: Capricorn Buff sandstone quarry sawn plinths and seating

Anzac Memorial Walk has national significance

I

n excess of 150 tons of Capricorn Buff sandstone was used to complete stages one and two of the Emu Park Centenary project.

The Memorial Walk forms a significant part of a Commemorative Precinct, which will be developed during the centenary years of WW1 (2014-2018).

The Precinct is designed to recall, preserve and honour our war heritage and those who fought and died in WW1.

The Memorial boardwalk is 175 metres long. The Memorial Court Precinct will initially feature a pictorial screen featuring the

work of local artists, a grassed mound and landscaping, which includes Gallipoli Pines. Further architectural works, seating and paving will be added over the next two years.

The quarry sawn plinths and seating blocks were generously donated by Capricorn Sandstone.

The blocks were hand-finished and inscribed by local masons.

The project was originally inspired by the late Ross Coulter, who designed the initial concept, which was endorsed and approved

by Livingstone Shire Council and the RSL.

any of the calls the Australian Stone Advisory Association (ASAA) receives relate to problems which arise after the stone has been installed. A considerable proportion of those calls relate to sealing, cleaning and maintenance. We decided to produce a basic Sealer Selection Guide in response to requests by contributors and readers of Discovering Stone.

We have attempted to make the ‘Guide’ as relevant as possible by focusing on use of three popular products, in specific locations and asking leading suppliers to nominate appropriate sealers.

However, our guide can only provide readers with basic information.

There will always be variables which have to be taken into consideration.

Our guide cannot possibly address every possible situation or environment.

Nevertheless, it does provide a valuable reference point and an insight into the available products from some of our leading suppliers. More than 50 companies in Australia are actively engaged in producing or distributing sealers for natural stone. Our guide largely features materials which have been tried and tested in the marketplace.

Understanding the limitations of sealers is also important. Sealers are designed to improve the natural stain resistance properties of stone – they will not provide 100 per cent protection against all stains in all situations. As an example, an impregnating sealer will not prevent marble or limestone being etched by acidic solutions such as wine or soft drinks; impregnating sealers are designed to reduce the absorption of stains and cannot provide complete protection to the exposed surface. Surface sealers (such as acrylics and polyurethanes) provide excellent surface protection by forming an impermeable barrier. The drawback of this feature is that any moisture below the sealed layer cannot escape and peeling of the coating may follow.

Participating companies can provide project specific advice, some also recommend approved applicators. We urge readers to seek precise advice before commencing the installation process. Our guide which is designed to encourage users to identify the right sealer and maintenance programme.

Melocco Stone, Snowy River Pearl

Our Guide has been emailed to over 7000 specifiers and members of the stone and tile industries. Recipients also received a copy of the Australian Stone Advisory Associations’ guide to ‘Sealing and maintaining natural stone’. Both of these documents are also available for free download from the Archived Articles segment/ page of www.infotile.com and the homepage of www.asaa.com.au.

T

he bush fires that occurred on Black Saturday had a devastating effect on Marysville and the local community. Approximately 90 per cent of the townâ&#x20AC;&#x2122;s building stock was destroyed and the main street was riddled with empty sites.

Metier3 Architects, Melbourne sought to partially alleviate the effects of this tragedy with their stimulating design of the new Vibe Hotel & Conference Centre located in this charming alpine village.

Construction of the $28 million project commenced in May 2013 and concluded in February 2015.

Australian Slate & Stone supplied a significant quantity of Kanmantoo bluestone, natural split rockface

materials, in small to medium formats coupled with some larger units. The stone was processed to provide 75 mm thickness facings, which were adhered to the exterior of the building.

Kanmantoo bluestone is quarried in the Adelaide Hills; the product is durable and fire resistant.

Over 90 per cent of the Vibeâ&#x20AC;&#x2122;s employees live locally. Since its opening, the Vibe has attracted more than 4000 guests and over 1300 delegates have attended conferences.

Kanmantoo bluestone has a variety of commercial and residential applications, which include paving, walling, steps, slabs, garden features and the featured cladding.

ASAA appoints new CEO and announces seminar program The Australian Stone Advisory association recently appointed Peter Mitchelhill, the General Manager of CDK Stone as the associations new CEO. The make-up of the new board is detailed in the interview with Peter, which appears below.

ASAA has also released details of the first in a new series of seminars. The first event will be held at Holmesglen TAFE in Melbourne on 22 June. Details of the presentations appear on the opposite page. It is anticipated that a second seminar will be held in Brisbane in October.

An interview with Peter Mitchelhill.

DS: Congratulations Peter. While you must be delighted about your recent appointment as CEO, there is a lot of work to be done?

PM: I am pleased but there is much to do and we need to take some positive steps in the right direction.

DS: Your predecessor Tony Stock published this magazine and was involved in ASAA from day one. In fact, he still contributes articles, which feature in Discovering Stone and Tile Today. Tony organised many events and activities. How will you replace him?

PM: One of the first decisions taken by the board was to invite Tony to become an administrator responsible for organising seminars, promoting membership and sales of our Natural Stone Design Manual, amongst other things. Tony was pleased to become involved. In fact, he confirmed his acceptance just in the last few weeks and is already busily organising events and promotional activities for the ASAA. It is a big step forward for us, for the first time we now have an Industry Liaison Officer focused on the activities and development of the ASAA. DS: What will his first task be?

PM: The board is anxious to develop and maintain a new series of seminars, which can hopefully be presented in several States. We have asked Tony to find a venue for an evening seminar in late June.

Hopefully we can promote that event in this edition, on the ASAA website and as part of our e-news program.

now. With Discovering Stone magazine about to be re launched and Tony Stock actively promoting the ASAA we expect the Design Manual to become a valuable contributor to the ASAA.

DS: You mentioned the website and e-news activities. How are these elements being managed?

PM: We took the opportunity to ensure that the directors represented, as far as is possible, all States and Territories. We used the association’s constitution to invite two additional directors, which will hopefully best represent the interests of all of our members. The current directors are: Carolyn Spralja, Cairns Marble (Queensland); Jim Mann, Stone Initiatives and Materials Testing Group (South Australia); Rolf Offerhaus, Ardex Australia (New South Wales); Bruno Repeti, Stone Concept Holdings (New South Wales); Mike Steel, BAM Stone (Victoria); Wayne Blakeney, Absolute Stone (Western Australia) and myself.

PM: Stephanie Thompson is handling the website and she will co-ordinate the transmission of e-news campaigns using ASAA’s resources and Elite Publishing’s databases of industry and specifiers, which they purchased from Australian Tile Publications.

The content will be prepared by Tony Stock in consultation with the board.

A big step in the development of our web site has been the addition of a section headed Services, which directs users to an expert in each state, who can address technical questions from users.

DS: You mentioned the board on a couple of occasions. Who are the current directors?

DS: Has membership decreased?

DS: The ASAA Natural Stone Design Manual is no longer available in a hardback format. How are digital sales progressing?

PM: The manual has not been promoted in Discovering Stone for over a year and we have not been active in terms of sending emails to potential purchasers but that will all change

70 | DISCOVERING STONE #28 | www.discoveringstonemagazine.com.au

PM: Actually the numbers are very similar to what they were at this time last year, but there is no doubt that we have to pick the ball up and run with it. Fortunately Felicity Stock still looks after our accounts and she promptly invoices members and handles that element of our administration. In fact, with Tony, Felicity and Stephanie

Thompson on board, we now have the original team that handled practically all the day-to-day activities of the association.

DS: How are you going to attract more members?

PM: Well, we obviously have to be more proactive and we have to develop strategies and benefits that will appeal to wider segments of our industry.

Let’s not forget that ASAA has presented many seminars, promoted Australian stone and the association at expos and conferences at home and overseas in China and Italy.

In addition, we have sold numerous copies of our huge Natural Stone Design Manual, which we produced with support from the Marble Institute of America. Leading architects, stonemasons and TAFEs use the manual. In addition, over 1500 individuals have downloaded our Guide to Categorising, Sealing and Maintaining Natural Stone, which we launched last year.

We also instigated the discussions that led to the introduction of the Good Environmental Choice Australia Hard Surfacing Standard, which is designed to allow manufacturers and wholesalers of stone and tile to gain an ecolabel for their product.

I’m pleased to report that foundation member Melocco Stone has gained

The MIA has approached us and is very keen to be involved in promoting the ASAA and by offering us products and services already offered to their members. I forgot to mention, the ASAA Architectural Stone Awards, which recommence in this edition, is yet another ASAA initiative that has attracted participation by some of the nation’s leading architects. We have done a lot of good things, but we can do more.
