ROOF REPAIR AT WOLLONGONG HOSPITAL Wollongong Hospital is the Illawarra and Shoalhaven’s major referral and teaching hospital and has more than 500 beds. The campus, which incorporates the Illawarra Regional Cancer Care Centre, provides a comprehensive range of inpatient, outpatient and community-based services. Sika Australia were invited by Advanced Waterproofing to provide a solution for the hospital’s leaking roof that had seen many years of service. The aim of the refurbishment work was to prevent further damage to the building that may have undermined its foundations or internal operations.

Due to the coastal environment, the speed of cure was important, as it lowered the risk of damage during the curing process due to changes in weather. The coastal environment also plays a large part in the long term durability of any exterior treatments, due to salt water spray, and this was a key consideration for the project. Advanced Waterproofing were able to successfully remove the existing failed sheet membrane and replace it with a liquid applied membrane that will ensure the roof remains watertight for years to come.

Sika provided Advanced Waterproofing with the new Sikalastic®-488 liquid waterproofing membrane, which was launched into the Australian market in mid 2013. This single component, UV stable, low solvent polyurethane liquid membrane, allowed for fast installation (using a brush and roller), creating no distruption to the service and function of the hospital during application . Sikalastic®-488 provided Wollongong Hospital with a durable roofing solution that will last for years.

The Kings Square redevelopment program is not a single building solution, but comprises four commercial buildings and three residential buildings, which will change the face of the Perth skyline and the way tourists and locals interact with inner city Perth. Sika Australia were pleased to recommend our SikaProof® A fully bonded, polyolefin based membrane system, featuring unique ‘grid seal technology’ to the project architects. After a lengthy period of detailed design input with key stakeholders, installation works were awarded to Citi Commercial Maintenance, a key contractor on the project. Work on Building 2, the first of the structures to be built, progressed rapidly in part due to the ease of installation of the SikaProof® A system. Sika provided solutions for the concrete foundations and underground areas of this building through October and November construction stages. A number of innovative Sika product solutions were used in the Kings Square development. First and foremost, over 4,500m2 of SikaProof® A proved to be an ideal waterproofing sheet membrane for in-situ poured concrete applications. The Sikaproof® A was applied beneath the insitu poured concrete slab and between wall sections. Sika Sarnafil®, another sheet membrane commonly used in roofing applications, was used as a tanking membrane to hold storm water within the structure. To ensure stability and watertight construction joints, SikaSwell® S-2 and Sikaswell A2010M were used. These swellable waterproofing products are hydrophilic and capable of providing long term performance even in the presence of contaminated ground water. Sika® WT 100AU is a liquid water resisting admixture used to reduce the permeability of concrete, creating yet another layer of water protection for the foundations of this building. SikaGrout® 212 was used in conjunction with Sikadur® 42, a solvent free epoxy-based grout, to complete the third party certified waterproofing of the pile caps. In fact all standard detailing solutions offered with the SikaProof® A system are third party tested and certified to be watertight.

BUILDINGS OF THIS SIGNIFICANCE NEED TO BE PROTECTED FROM THE OUTSET WITH THE USE OF COMPREHENSIVE WATERPROOFING SOLUTIONS TO PROVIDE PROTECTION AGAINST WATER INGRESS, AND AGAINST FUTURE CONCRETE DETERIORATION.

MULTIPLE PRODUCT SOLUTIONS The combination of SikaProof A Sheet membrane and the SikaGrout-212 used in the pile caps (as seen above) has created a completely watertight solution for this project.

NEWS FROM SIKA WORLDWIDE Sarnafil USA, Massachusetts. Student housing has long been seen to serve both an economic and a social purpose. If you have ever lived in tiny, shabby student accommodation while at the same time enjoying the student highlife, you are bound to be astonished by this stunning student housing project. RANKED #2 GLOBALLY The Simmons Hall student dormitory is inside the campus of Massachusetts Institute of Technology, which is ranked the second most powerful university brand in the world. There are more than 10,000 students studying there from all over the US and 100 countries worldwide. Many former students have won Nobel prizes for outstanding peace activities, economics, chemistry or medicine.

HIGH-END USER FACILITIES Simmons Hall stands 10 stories high and houses 350 undergraduate students. The building is punctuated by terraces and atria and includes a computer cluster, fitness center, a multi-purpose room, a game room, music rooms, street-level dining, a 125-seat theater as well as laundry facilities and kitchenettes. FIVE COLOURS MEMBRANE The unique architectural building utilises over 24,000 square feet of Sarnafil® membrane in five custom colors – blue, green, red, yellow and orange. Because of the dorm’s irregular shape, stagings were used to lower the membrane down several stories. Separate crews adhered the felt-backed membrane to vertical walls and overhead soffits at each story level, following a specific color design pattern. Applying Sarnafil membrane to vertical walls, rather

than to horizontal surfaces. This is a highly unusual application and was done to achieve the desired color plan. CAMBRIDGE LANDMARK Simmons Hall’s bold geometry is already a Cambridge landmark. The shimmering exterior is wrapped in more than 5,500 windows connected by a grid of anodized aluminum. So the building reflects during the day and glows with interior light after dark. The design of the windows provides lowenergy ventilation and dehumidification. In addition, the exposed interior concrete supports night ventilation and maintains cooler temperatures during the day. And now you tell me… Who among you would not have wished to have spent their first semester there?

TRADING CONTINUES AS SIKA DELIVERS FLOOR UPGRADE The Sydney Fish Market, situated on the edge of Blackwattle Bay in the inner city suburb of Pyrmont has been an institution since 1945. The market is the largest of its type in the southern Hemisphere and is among the largest in the world, where 50 tonnes of seafood are auctioned on the trading floor each day. The floor has to withstand constant, loaded fork lift traffic in the access-ways as well as crates and pallets full of seafood being continuously dragged across the trading floor. The floor is also constantly wet, a challenge for any flooring solution.

SYDNEY FISH MARKETS, NSW

A HIGHLY DURABLE FLOORING SYSTEM Sika has provided a complete flooring refurbishment solution for the iconic Sydney Fish Market. Installed during a live trading period, the eight stage project delivered a new food-grade standard floor that withstands heavy traffic and excess water. The Sydney Fish Market is situated on the edge of Blackwattle Bay in the inner city suburb of Pyrmont and has been an institution since 1945. It is the largest working fish market in the southern hemisphere, trading 50 tonnes of seafood each day. It is also home to six seafood retailers, a bottle shop, grocer, restaurants, gift shop and deli.

As part of a large facility upgrade, Sika and Danlaid Contractors Sydney were appointed to refurbish the fish market’s deteriorating floor. After many years of installing a variety of protective floors with varying results, the condition of the floor was poor and failing in most places. The project required the new floor to meet food grade standards, withstand heavy foot and forklift traffic, and tolerate excess water on its surface. As an added challenge, the floor had to be demolished, prepared, re-graded and laid in stages while the market continued to trade. This required immense planning between all parties as well employing methods of preparation such as hydro blasting to ensure no airborne dust particles were generated at all. For owners or controllers of food and beverage manufacturing facilities charged with finding a long term solution for their production floors, it can be a very daunting task to understand the difference between all of the systems on offer and their appropriate use. A number of criteria need to be taken into consideration when selecting a food flooring system. Impact, cycles of traffic, chemical exposure resistance to thermal change, texture and clean ability are all factors that contribute to durability and the overall life of the floor. “Despite several previous upgrades, the existing floor was in terrible condition and 30 to 40 millimetres was demolished, along with defective concrete substrates. The floor was then re-graded to create positive falls for water displacement. An epoxy sub-fill mortar was used to recreate the levels,” said Anthony Lewis, Market Field Manager – Flooring at Sika. Polyurethane Concrete products such as Sikafloor® PurCem® have been available to the food flooring industry for some 25 years on the international market. As the name suggests, this technology is a mix of water based polyurethane and cement technologies, which brings together the benefits of both chemical reactions. The cement properties bring the properties of concrete, such as durability, strength and low wear to the flooring system. Polyurethanes provide the resistance

level of poly-resin, together creating the perfect food-grade floor protection. The properties of PU concrete are well suited to industrial food production. Impact resistance comes from its ductility, while thermal shock and high temperature resistance (-20 to +120 °C) comes from the cement component. These floors also also provide a high degree of chemical resistance to the normal range of food acids and cleaning

chemicals used in food manufacturing.

Sikafloor® 22 PurCem®, a low VOC waterbased polyurethane screed, was selected to finish the floor. Certified for the food industry, it is slip resistant, heat resistant and is easy to maintain and clean.

PU Concrete has a proven history in Europe for 30 years, but has previously been expensive to produce and costly to import to Australia.

It is particularly suited to food and beverage processing plants, wet or dry process areas, freezers, coolers and thermal shock areas. The job faced a host of unique challenges. “This was our most difficult project ever. Upgrading the floor during a live trading period meant effective project management was critical. It was also important to use a flooring solution that minimised disruptions to trading operations,” said Matthew Dial of Danlaid Sydney, the contractor appointed to the project.

Local production of the product from some manufacturers recently has brought the cost to install down to be very competitive with all other floor options. This cost competitiveness, together with these performance features a very tough fast to install, long lasting floor systems.

To allow trading to continue, the existing floor was cordoned off in sections and the upgrade was completed in eight stages. As a fast application solution, Sikafloor® 22 PurCem® allowed each section to be re-commissioned quickly and efficiently, reducing down time.

Polyurethane Concrete is the best all round flooring solution for food environments.

Sikafloor® 22 PurCem® is the same flooring solution that was specified for both Coca Cola Amatil and Coles

Whilst not being as rapid to cure as reactive based resins, PU Concrete is faster than epoxy and can be accelerated to execute short down time applications such as smaller turn around projects as well as isolated infill and repairs

There is now a wide spread adoption of this technology in all areas of the food industry, from national manufacturers, small producers and processors to restaurants and commercial food outlets.

Supermarkets over the past year. This shows a clear dominance of this technology in situations where a highly durable solution, coupled with professional contractors and supplier service are required to not only complete the job, but ensure that it continues to serve for years to come in these demanding conditions. “Each completed section was quickly re-opened for trading, which meant the floors were constantly wet as seafood was moved around the markets. Sikafloor® 22

Purcem® is able to tolerate high levels of moisture in the concrete, making it ideal for this project,” said Danlaid. “We also had to consider how the upgrade could impact customer experience. As a low odour product, Sikafloor® 22 Purcem® didn’t taint the fish and customers didn’t experience smells that could impact sales,” added Dial. The floor refurbishment formed part of a larger and more complex overall facility upgrade, so meeting project budgets and timelines was critical. “Sika was able to deliver a high volume of stock on time and on budget. By offering the whole system, I had the convenience of a single point of contact without needing to work with multiple suppliers,” said Danlaid.

Over the past 10 to 15 years, the use of colour in concrete has grown so rapidly that the concrete industy has become the world’s largest consumer of iron oxide colour pigments. Architectural projects can now be enhanced with colour and design effects to complement the natural soroundings. The introduction of iron oxide slurry or liquid colour has been a result of technological advancement in the industry. Liquid colours are high in solids dispersion of iron oxide pigment in water with total pigment levels between 6070%, resulting in a more consistent colour mix. Using the latest state of the art Sika equipment, the Sika ColorFlo® machine can electronically measure how much colour pigment went into the mix, taking out the human error in the process and provide consistency in generating colour concrete in any conditions. In order to produce an aesthetically appealing design accross the entire Adelaide Oval redevelopment, architects provided specifications for both the background colour of the concrete as well as the aggregate colour and size. Matching these specifications were critical to ensure the concrete tied in with the entire design and colour scheme of the redeveloped stadium and its surrounds. After reviewing many samples, Sika and Hallett Concrete were able to put forward a suitable solution that satisfied the architect’s colour requirements. Sika were able to provide approximately 2,000m3 and one bag (6kg) of SK288 (Ginger) to colour the concrete of the pedestrian area surrounding the stadium. This equated to approximately 12 tonnes of Sika product. The end result was an aesthetically pleasing concrete pedestrian area, that will provide decades of use for events held in the redeveloped stadium.

CRITICAL TO COORDINATING THE ENTIRE DESIGN OF THE REDEVELOPED STADIUM WAS ENSURING THAT ALL CONCRETE COLOUR MATCHED THE ARCHITECT’S ORIGINAL SPECIFICATION. .

STRONG PARTNERSHIPS WITH SUPPLIERS Hallett Concrete / Ossmic Concrete Constructions were proud to supply the concrete, trucks and mixing equipment used to deliver this beautiful coloured area on site.

SIKA PRIMER MR FAST FOR TIMBER FLOORING

For many years, in a range of industries, the question of having a huge variety of primers depending on your adhesive or waterproofing membrane was raised. Why not have a universal primer that could be used with everything and make everyone’s life easier? Sika® Primer MR Fast is that primer. Sika Australia have recently introduced the product, designed for a wide range of applications from under waterproofing membranes to aiding in bonding timber flooring to concrete substrates. This product is not something completely new to Sika. The Sika® Primer MB offered many of the same features and benefits. However, Sika® Primer MR Fast is low odour, thus being better for use in confined, internal spaces, while still offering the same features and benefits.

SYNERGY MAGAZINE ISSUE #6

Sika® Primer MR Fast is a water-based Primer and moisture control coating for added adhesion to SikaBond® adhesives. Its water-based, solvent free formulation allows for easy application and easy clean up, perfect for use on site. By applying Sika® Primer MR Fast to the substrate, contractors can reduce adhesive consumption, as the primer prevents adhesive absorbtion by the substrate and promotes adhesion to the timber flooring above. With a short waiting time of four hours between coats, a faster return to service is achievable in all uses. Sika Primer MR Fast can be used with subfloor heating, for refurbishing existing substrates and is compatible for use with all SikaBond systems for wood floor bonding. Sika® Primer MR Fast can be applied quickly and easily, thanks to its simple two part

formulation. Instead of time consuming mixing and preparation, you simply empty the Part B container into the Part A container and shake well until a homogenous colour and texture is achieved. This saves time for applicators on site, saving money for owners. Sika® Primer MR Fast should be applied uniformly, in one or two coats depending on substrate condition and porosity, using a nylon roller to give a wet look surface finish. The white tinted colour of the product in its liquid form makes it easy to distinguish the coverage of one layer from the substrate. As the Sika® Primer MR Fast dries, it cures clear colour, creating a polished-looking surface. Once applied, you can normally proceed after just for hours, applying Timber Flooring adhesive and Timber Floor finish. For complete system solutions for Timber Flooring, Trust Sika.

GOLD COAST LIGHT RAIL CONSTRUCTION The Gold Coast light rail project is one of the biggest public transport projects in the country, and the biggest transport infrastructure project ever undertaken on the Gold Coast. As Queensland’s first ever light rail system, it represents a major step forward in transforming the city into a modern, accessible destination. Once completed, the system will provide a reliable transportation solution between Griffith University and Coolangatta. The first stage of the project will service the 20,000 plus predicted student population at Griffith University, along with the thousands of staff, students and visitors who will frequent the new 750-bed Gold Coast

University Hospital that is currently under construction at Parklands Drive in Southport. Given the size and nature of the project, significant importance was placed on the strength and securing characteristics of all components and materials used in the construction of the network. This ensures a stable foundation for the tracks and ultimately the safety of all travellers. Given the safety requirements, the client requested that the products used had been used on other similar projects to their reliability had been proven in a similar environment. Due to the land surrounding the site being reclaimed and the soil movement under the

tracks being engineered to allow for future track adjustments, a precision grout was required for the project. SikaGrout®-212HP matched the specifications and was used for the grouting under the light poles and the viaduct baseplates to ensure all components were properly secured. SikaMonotop®-412 NFG was used to carry out repairs on large slabs during construction. Sikaflex® PRO was used to seal the joints in and around the anchors as well as the rail base plates to prevent liquid ingress and ensure a watertight seal, ensuring overall structural integrity.
