Identifying the damage

Type of damage

- Concrete is a composite material that consists essentially of a combination of fine and coarse aggregates bonded with a paste resulting from the portland cement hydration. - The distress of the reinforced concrete is a result of the presence of three simultaneous factors: interconnected porosity, presence of water or moisture and exposure to agressive agents. - Concrete can be damaged by many processes, that are divided into 4 types: physical,chemical, mechanical and application damage.

Physical damage Physical damage occur due to fire, water leakage, shrinkage, abrasion or freeze/thaw cycles.

Chemical damage Chemical damage occur due to carbonation, chloride, sulfate attack or Alkali Silica reaction

Type of damage

Mechanical damage

Application damages This type of damage can be related to lack of concrete vibration during the pouring, wrong water/cement ratio, lack of demolding agents, insufficient curing...etc.

Honeycombs are formed because of a lack in concrete vibration and low malleability.

Pinholes result from inconvenient water/ cement ratio and / or lack of shutter release oil.

Identifying the damage

Mechanical damage occur due to movements, overloads or impact.

Different types of cracks can appear after demolding and setting of the new concrete.

Identifying the damage

Concrete diagnosis If the concrete is not designed and applied properly, steel reinforcement may be corroded,could increase in volume and push the concrete to crack and delaminate and consequently provoke further deterioration. They are 3 methods to identify damage in concrete:the visual inspection, the physical inspection and the quantitative inspection.

Delamination Corrosion limits are generally greater than delamination area

Steps after damage identification: 1- Defected areas should be delimited using a marker pen by drawing a line around the perimeter of the damaged area. 2- Break out the marked areas using a light jack hammer until reaching sound concrete. 3- If sound concrete is reached before reaching steel bars, then the repair will be restricted to the concrete surface itself. 4- If sound concrete is not reached, breaking of concrete should continue until the steel reinforcement bars appear. 5- If steel reinforcement bars are found corroded, breaking should continue beyond the corroded part until reaching sound steel re-bars

Identifying the damage

Concrete diagnosis

Quantitative inspection Compressive strength test In order to assess the compressive strength, samples are taken from the concrete and tested. From fresh concrete, samples are molded into cylinders that are crushed upon 1, 7 and 28 days. For old concrete, samples are taken by coring cylinders out of the element in question. Low compressive strength is explained by high porosity, making the concrete vulnerable to carbonation and chloride diffusion.

Coring Test

By all means, the minimum compressive strength should be determined by the stuctural engineer.

Carbonation depth test Exposed concrete may be attacked by carbon dioxide present in the air. CO reacts with the free lime present in the concrete Â˛ to form water and calcium carbonate, harmful to the reinforcing steel.

Solution of phenolphthalein in ethanol

Carbonated Layer(Clear) shown hatched on illustration

The measurement of carbonation depth using phenolphthalein solution is carried out by spraying the solution on the surface of the concrete. Surfaces with pH below 10 (carbonated) will have no change in color, with a pH above 10 the color of concrete will change to a pink color.

Chloride diffusion test Concrete exposed to the sea is extremely vulnerable to chloride ions diffusion. Chlorides are acid air borne gases. Once they reach the steel reinforcement, in the presence of oxygen, they destroy the passivity of the steel and provoke corrosion. Colorimetric method is a quick and simple method to measure the penetration depth of chloride by spraying a silver nitrate solution.

Concrete repair - Case 1

Repair of cracks in reinforced concrete Causes of concrete distress Cracks are the most frequent signs of concrete problems. A crack is a linear fracture in the concrete caused by tensile stresses exceeding the concrete tensile strength. Cracks in the plastic phase of concrete • There are cracks that develop in the plastic phase of the concrete such as plastic shrinkage cracks due to insufficient early curing and loss of water by fast evaporation. • Plastic settlement cracks appear when the concrete consolidation is restrained by the steel bars. Cracks in the hardened phase of concrete • Some cracks develop in the hardened state of the concrete such as drying shrinkage crack, due to insufficient movement control and Thermal Shrinkage. Cracks develop in massive concrete due to sudden drop in ambient temperature as compared to the heat generated by the concrete. • Other types of cracks can develop occasionally, in cases such as freeze and thaw cycles, Alkali silica reaction or structural distress. Some of them run linear and deeper through the thickness of the member and others are short in different directions while they remain on the surface. However all above cracks, if left without treatment, will make the concrete vulnerable and will lead to steel corrosion and further deterioration. Before undertaking any repair, a field investigation and structural analysis should be completed in order to establish the causes of the cracks. Cracks are divided into dry cracks and Wet cracks. In this section, we are treating the linear dry cracks only; wet cracks will be treated in the waterproofing section.

Non Moving Linear Dry Cracks

Linear Dry Cracks in reinforced concrete should be strengthened and consolidated using Conrep.i 650. It is a low viscosity 2-component epoxy injection resin capable to fill the full depth of the crack. The following steps should be observed: • All cracks should be fully dry. • Injection surface packers should be placed with equal distance between them. Clean thoroughly the surface of the crack and seal each packer using Conrep.412 CRY, an epoxy adhesive.

• The same adhesive Conrep.412 CRY should be used to seal the whole surface of the crack to play the role of capping in order to prevent the Conrep.i 650 from escaping during injection. • The work process requires the use of an injection device that could be manual, pneumatic or electrical. The injection starts from the lowest packer and stops when Conrep.i 650 appears from the next packer. • Close the same packer with its nipple and inject it with Conrep.i 650. Continue working the same until all the sealed packers are injected. • Remove capping by scrapping and grinding. Moving Linear Cracks For Moving Linear Cracks replace Conrep.i 650 with Conrep.i 600, a low viscosity flexible 2-component polyurethane resin which reacts to form a flexible seal.

Concrete repair - Case 2

Repair of damage with exposed steel reinforcement

Surface preparation Before undertaking any concrete repair, care should be taken to fix props and supports around the location to be repaired, especially in the surroundings of damaged columns and beams. The following surface preparation is recommended:

STEP 1: • By using a marker pen, delimit the area of damage. • Break beyond the delimited area until reaching sound concrete and steel. • With a jack hammer, saw-cut 2 cm deep in 90° angle the perimeter of breaking, in order to avoid feather edges. • All weak, damaged and easily removable concrete should be chipped away. If the re-bars are only partially exposed after all unsound concrete is removed, it may not be necessary to remove additional concrete to expose the full circumference of the reinforcement. When the exposed reinforcement steel has loose wrap, corrosion or is not well bonded to the surrounding concrete, the concrete removal should continue until a clear space of 15 to 25 mm is created behind the reinforcing steel.

STEP 2: • Clean steel reinforcement with mechanical wire-brushing or by sand blasting. • In case the reinforcing bars are corroded and have lost more than 25% of their diameter, they have to be cut and removed.

STEP 3: • In such event, removed steel bars should be replaced with new steel bars of the same diameter either by respecting the overlap length or by welding 100 mm length to the existing steel

STEP 4: • Remove dust by air blowing and wash with clean water to achieve a Surface Saturated Dry (SSD) substrate.

Repair of superficial concrete damage

Surface preparation Shallow damages in old concrete may occur by contamination. As previously mentioned in the Concrete Diagnosis, it may also occur due to accidental impacts, abrasion, erosion or freeze / thaw cycles.

In the freshly casted concrete, superficial damage are revealed as honeycombs with exposed aggregates, pinholes or surface imperfections. In case of honeycombs, imperfections are chiseled until sound concrete is reached. Then, the surface should be cleaned from dirt, dust, paint and laitance by grinding or air blowing. Surface should be dampened with water to surface saturated dry prior to any repair.

In case of pinholes, surface should be dampened with water to surface saturated dry prior to cementitious repair. In case of using epoxy based products for repair, water should not be used on the surface in any circumstance. The area should be grinded in order to get rid of laitance, paint or any covering material, and then should be cleaned with an air blower.

Repair of damaged slabs and horizontal elements

Surface preparation The surface preparation of horizontal elements aims to eliminate all defections and assure horizontality of the slab or element. The surface should be grinded to put out the slab level; and then cleaned from dust, grease or any other material that could prevent the adhesion of the repair product. Where the element has a small differentiation in leveling, grinding would be enough for the leveling. In case of bigger slope difference, it is recommended to use a scarifying machine before grinding the surface.

Bedding of machines plates

Machinery and equipment which have precise tolerances for alignment or require uniform support cannot be placed directly on finished concrete surfaces, therefore grout is poured and plays the role of a load transfer material between machine or equipment bases and their foundations. The support provided by a grout is the Effective Bearing Area. This can be affected by grout leakage, unlevelled plate, shrinkage of grout, inadequate mixing of grout, wrong placement method, poor grout flow or entrapped air voids. EBA can lead to point loading on the grout which in turn can result in cracking and crumbling of the grout under the baseplate. This could have disastrous consequences on the machine.

Bedding application problems Voids in the grout

The support provided by a grout is the Effective Bearing Area. This can be affected by grout leakage, unlevel plate, shrinkage of grout, inadequate mixing of grout, wrong placement method, poor grout flow or entrapped air voids. It can result in cracking and crumbling of the grout under the baseplate.

Cracks in the grout around the baseplate

Cement grouts rely on expansion to provide the non-shrink properties required of a precision bearing grout. This expansion needs to be confined under the baseplate, but if allowed to expand freely, the grout may crack due to shrinkage. This cracking is often seen where a cement grout has not been finished properly. Epoxy grouts are not affected as much as they have low inherent shrinkage.

Grout not flowing under the baseplate

Rapid installation of machinery is essential. A grout with poor flow will slow down the process. Some inferior epoxy grouts are cut back with diluents to improve flow but this can lead to excess shrinkage. Sodamco-Weber grouts have been developed to give good flow without any undesirable side-effects.

Repair of manhole covers and grids

Road ironwork such as manhole covers, road gullies and duct covers need to be bedded with a resilient mortar to prevent the unit rocking or breaking up under traffic loading. Often the reinstatement of ironwork is done within traffic possessions under temporary roadworks and the time to reinstate is a critical factor.

Constraints

The road needs to be rapidly set back to traffic, to avoid a too long traffic interruption

Ceiling of manholes should be quickly efficient, to resist to the weight of cars passing over it. A traditional site-mixed sand/cement bedding mortar will crack and crumble under traffic loads, resulting in premature failure of the cover and frame.

The final aspect of the manhole is important and it should be integrated in the road design

Clean dust and other materials, remove traces of oil, grease, etcâ&#x20AC;Ś by brush or air-blowing

Humidify the area where the mortar will be laid. It should be wet but not waterlogged.

Substrate preparation

Break and cut 10cm around the manhole at a 90 degrees angle

Application Mortar preparation Prepare a plastic consistency mortar by mixing a 25 kg bag of Conrep.314 RD with 4 to 5 liters of clean water. Mixing must be done for at least 3 minutes until a homogeneous paste is obtained. Do not mix it with another hydraulic binder (cement, lime or gypsum) or an admixture.

Mortar application: Conrep.314 RD must be used within 10 minutes (at 30ºC) from mixing. Re-mixing with an extra amount of water is not recommended. Apply Conrep.314 RD on the substrate. The thickness under the frame should be at least 3 cm. Ideal application temperature is between + 5ºC and + 35ºC. If the application temperature is higher than 35ºC, make sure to use cool water to keep the mixed mortar temperature below 30ºC.

Placing the frame Place the frame and adjust it to road level (the grid/manhole should be perfectly adjusted and integrated in the road to avoid deterioration of the grid/manhole and to avoid damaging the cars when passing on it. Do not use wedges (metal, wood…)

Finishing Fill the gap between the frame and the road with Conrep.314 RD with a trowel. Then Finish with a float and level the mortar to road level, to have a perfect flat finish. After application, protect the surface by using a curing compound like Cure WT or Cure Y 40 or by covering with properly secured plastic sheeting.

Sealing of construction and/or expansion joints Expansion joints and construction joints Recommended products

Waterstops

Swellbar

Swellbar RB

PVC Waterstops are recommended to stop leakage positively through construction and expansion joints in concrete structures. They are required whenever concreting is to be made in 2 phases (between slab and slab or slab and wall or wall and wall).They are installed within the reinforcing steel before concreting. During concreting, one part is immersed in concrete while the other is kept free until the second phase of concreting takes place. They are made of flexible PVC and are available in different sizes and types. Swellable waterstops are recommended for construction joints. They are present in two types: Swellbar is a mix of bentonite and butyl rubber, and Swellbar.RB is a swellable waterstop in pure rubber. They have the ability to expand in presence of water. The expansion process is slow in time. It starts after 4 hours, hence enabling the concrete to set. They are present in different sizes, depending on the degree of protection required. Swellbar (SQ type) joint sealant are developed for use in both fresh and sea water.

Application of swellable waterstops and PVC waterstops • Uneven wet surfaces should be even, and hardened rough surfaces should be smoothened with the appropriate grinding machine, to install the swellable waterstops. • Use steel nails for fixing, a 25 to 30 cm interval is necessary between nails. • PVC Waterstops are tied to the reinforcement steel bars with steel wires through the holes in the perforations in the waterstop. • Overlap joints in the strips should be made at least 75 mm. Butt-joined is also acceptable but has to be carefully stuck down with mastic.

Sealing of construction and/or expansion joints Sealants for joint width smaller than 30mm

Jointseal.PU

Jointseal.PU is a reliable low modulus polyurethane joint sealant, allowing a high degree of elongation after stretching. It recovers its performances and it is resistant to climatic ageing, rain, salt haze, ozone, ultra-violet rays and atmospheric corrosion.

Product application • The edge of the joint to be treated should be free from laitance, dirt, oil and grease. • Using a grinding disc or any abrasive tool, clean the lateral surface of the joint • Insert inside the joint a flexible backing rod having a diameter 5 mm bigger that the joint’s width. • Place the backing rod at a depth not exceeding the joint’s width. • Insert the sealant inside the dispenser gun and start filling the prepared joint. • While filling use a knife to press fully the sealant on the lateral surface of the joint. • Finish the surface of filling with the bottom curvature of a spoon dipped into a soap detergent.

Waterproofing of raft foundations Waterproofing of immersed underground structures requires permanent dewatering during the execution phase and continues until the pressure caused by the weight of the concrete structure exceeds the hydrostatic pressure exerted by the water table. The type of foundations designed for such structures is most of the time raft foundation with or without piles, or a combination of raft and pile caps, depending on the bearing capacity of the soil. In such cases, the waterproofing is called tanking as it envelops completely the structure from the bottom to the water table level and preferably to the ground floor level. The waterproofing of the vertical part will start only when the full foundation raft/pile caps are casted.

Conrep.i 600

Conrep.i 610

For instant leakage stopping, a PU injection foam is recommended. Conrep.i 610 is a low viscosity water reactive polyurethane injection composed of a resin component and a catalyst.To stop leakage and form a permanent elastic membrane,inject Conrep.i 600,a flexible water sealing 2 component polyurethane resin that reacts with water to form a hydrophobic seal. Conrep.i 600 reacts in wet or dry cracks and joints. When Conrep.i 600 comes in contact with water, it reacts into a flexible seal.

Product application • Drill a hole in the concrete at 45 degree angle in order to intersect the crack or the leaking construction joint. • Place the bore packer inside the hole and tighten firmly in order to prevent the resin from escaping. The distance between each packer should not be more than the thickness of the structural member. The injection bore packer is designed with non-return valve in order to prevent resin from escaping during injection. • Injection bore packers should be placed and distant equally. • The injection requires the use of an injection device. Mix the 2 components of Conrep.i 610 and place in the container reserved in the injection machine. • Place the nozzle of injection hose inside the bore packer nipple. • Start injection and continue while the Conrep.i 610 is transformed into foam. • Stop injection when the pressure gauge reaches 75% of its highest value. • Remove the injection hose and shift to next bore packer and restart injecting Conrep.i 610 • When all the bore packers are injected, repeat the same process using Conrep.i 600.

Surface preparation • Surfaces to be treated must be thoroughly inspected.The concrete surface must be cleaned and free from oil, grease, paint, loose dust,mud and laitance. Horizontal surfaces should not have curing agents or hardeners applied prior to the application of weber.dry crystal. • Honeycombs should be hacked off to expose the concrete. All dripping and loose particles should be removed, clean surface with water before repairing. • Ensure all concrete surfaces are hosed down with water as moistures must be present in the capillaires prior to the application of weber.dry crystal. New concrete must be at least 3 days old before it should be treated. • Do an angle fillet of 25mm x 25mm at all junctions between slabs and walls with Conrep.331 TX, after making a V groove on all these junctions. • If surfaces are too smooth, the concrete should be acid etched lightly sandblasted or waterblasted. • In case of water leakage, an injection is performed through the leaking craks or plugging mortar into leaking holes.

Product preparation Mix each 25 kg of weber.dry crystal with approx 7.5 liters of cool water and stir thoroughly for at least 3 minutes into a flowable thick consistant slurry. The mixture should be used within half an hour, after which time it will start to thicken. Never add extra water to restore workability.

Product application • After insuring that the surface is moist without being visibly wet, apply weber.dry crystal using a brush or broom with fine bristles. • 2 coats at 0.5 kg/m² per coat are normally required. The coats are installed in 2 passes. • When the first applied coat is in tacking condition, the second coat is applied with a counter cross application to the first. • Hose down the entire surface of the treated area twice a day for at least one day. • Protect it from sunlight, frost, wind and rain for 5 to 7 days.

Waterproofing of accessible roofs and terraces

2- Protection 2-a Soft protection Recommended products

Geotextile.white PET

Gravel 5 cm

A protection is called soft when gravels or pebbles are spread over the horizontal waterproofing membranes to an average thickness of 5 cm. (to be applied only for rooftops lower than 15 m height) An underlay of Geotextile.white PET should precede the spreading of gravels in order to avoid puncturing of the waterproofing membranes placed underneath and separate it from the gravels / ballast.

2-b Hard protection Recommended products

weber.col floor

Jointseal.PU + Gun

Fiberglass mesh

A protection is called hard when the waterproofing membrane is covered with tiles. There are two ways to proceed with hard protection: • Loosely laid tiles are concrete tiles of sizes around 40x40cm and 3 to 4 cm thick. They are laid loose over the soft protection described above. • Mortar laid tiles are tiles laid over a bed of cement mortar like weber.col floor (Carromortar) range,eliminating the gravels described in the soft protection while keeping the geotextile as separation and protection layer. • Expansion joint of 2 cm wide should be provided in bays of 3x3 m and filled with Jointseal.PU or Jointseal.PU - MC. N.B. In case of hard protection it is recommended to replace the Primer of the horizontal area with a separation layer made of Fiberglass mesh. Hence, torching of membrane will occur only over the overlaps in order to provide a fully independent system.

Waterproofing of accessible roofs and terraces 2-c Thermally insulated roofs and terraces (Inverted roofing system) Recommended products

Geotextile.white PET

Xps board

In case of thermal insulation is required, use extruded polystyrene (XPS) of thickness depending on the amount of thermal conduction (U-value) designed. In all cases the XPS boards of a density around 30 to 35 kg/m続 have to be used. They are laid and staggered over the waterproofing membrane. An underlay of Geotextile.white PET should precede the laying of XPS in order to play the role of separation layer.

Cracked joints or loose parts should be removed and replaced with ready to use filling mortar weber.joint perfect or weber.cal stone of a color to architect’s choice. • All joints surrounding windows and doors should be filled with Jointseal.PU, or Jointseal.PU - MC a polyurethane sealant. • Wash the area to receive the water repellent with a water jet to remove all dust, laitance, or any foreign materials.

Application of a water-repellent product on the stones Waterproof.132 WB is a ready-to-use surface waterproofer made of siliconate, intended to leave a colorless, hydrophobic coat on inorganic construction materials. The product has a strong penetration into the material because of its low molecular weight. • Allow the washed surface to dry for 2 to 3 days. • Apply first coat of Waterproof.132 WB by roller on the entire area to cover, and within a limited period of time (10 to 30 min) depending on ambient temperature. • If the first coat is fully absorbed by the pores, apply a second coat. If not, stop application. • If the second coat is fully absorbed by the pores of the surface apply a third coat. If not stop application. • The second and third coat must be applied before the previous layer is totally dry (wet on wet). • Continue until the complete surface has absorbed Waterproof.132 WB. Do not overcoat.

N.B. Substrate should be put through all necessary tests, substrate should be porous, not treated or manipulated with and dry while application.

SURFACE PREPARATION Remove dust, oil and any remaining particles using grinders and fresh water only.The substrate must be sound and clean. PRESENCE OF HOLES Mostly in new built watertanks, holes will appear caused by molding or else. Such holes must be clean and damp.Use Waterproof.150 BLC - a fast setting plugging mortar and keep it moist for a period of 15 min. if any cracks are present, they can be treated the same way.

Watertank treatment

LARGE HOLES AND DAMAGED CONCRETE In the case of large holes or damaged concrete in old or new water tanks, all damaged areas must be chiseled, cleaned and damped with fresh water. Conrep.331 TX is to be applied in one or two layers depending on the holes. JOINTS TREATMENT All joints between vertical walls and the ground must be treated by creating a groove of 2 cm depth and 2 cm width. The groove is to be cleaned and damped with fresh water, then filled with Waterproof.150 BLC.In order to protect the filled joint, Conrep.331 TX needs to be applied on the 90° corner in a round shape and in an appropriate thickness after roughening the surface.Curing during 3 days is recommended in areas where Conrep.331 TX is applied. WATERPROOFING LAYERS After ensuring that all the above steps have been maintained, the watertank is ready to receive the final product, weber.dry 110 FX, a cementitious waterproofing membrane. Apply the 1st layer of weber.dry 110 FX with sufficient thickness (1kg/m²) with a brush or a roller: • Fix 20 cm width of Fiberglass mesh on all corners, joints and cracks while the waterproofing layer is still wet • When dry, apply the 2nd and 3rd layer of weber.dry 110 FX in proportion of 0.5 - 1 kg/m² • Application should be in two to three crossed layers with a minimum thickness of 2 mm.

Waterproofing - Case 9

HONEYCOMBING In some new built watertanks, honeycombing may be found after concrete pouring or pumping. Honeycombing areas must be cleaned by removing all damaged concrete and existing laitance. Damp the concerned areas with water and use Conrep.350 NSG for ﬁlling the cracks.

Waterproofing - Case 10

Waterproofing of swimming pools

Concrete walls or hollow-block walls are not sufficient to ensure a full waterproofing and avoid leakage. A full waterproofing system should be applied before putting the swimming-pool in service.

Constraints

Weak points such as pipes, water inlets and underwater windows are weaknesses in the waterproofing system.

Any concrete stucture has weaknesses such as wall/ slab connection, porous areas,construction joints...

When the pool is empty,the waterproofing mortar is submitted to the pressure from the surrounding soil.

The waterproofing mortar should also be compatible with the coatings used in the pool.

When the pool is full, the waterproofing mortar is under the pressure of the water in the pool.

At the proper volumes, Conrep.302 HF may be used as a micro-concrete by mixing it with clean and water-saturated 3/8 aggregates to a plastic consistency. Do not mix with other hydraulic binders. The use of additives is absolutely prohibited. Ideal application temperature is between + 5ºC and + 35ºC.

Conrep 302 HF Highly fluid expansive mortar for bedding

and anchoring

• Expansive • Highly fluid • High early mechanical resistance • Good resistance to sea water • Easy application • Perfect for bedding

APPLICATION METHOD Bedding Thoroughly scab the foundation, clean the area between the foundation and machine base-plate, as well as the anchor holes. Build a solid leak-proof formwork. Saturate the concrete foundation with water for a few hours prior to pouring. Remove all residual water. Pour Conrep.302 HF continuously, in one direction to avoid air pockets (by gravity, loading, pumping, injection). The choice of installation method depends on the grouting thickness and the length of the machine. The grouting thickness must be between 3 and 6 cm for a pure mortar. Larger thickness may be filled by a micro-concrete with the addition of 3/8 aggregates. Once the mortar starts to set, apply on its surface a curing compound or if the configuration and the tightness of the forms allow it, pour 1 to 2 cm of cool water over the surface and leave it there until removal of the forms. Anchoring The hole diameter should be at least equal to the rod plus 30 mm. Depth of holes: 10 to 15 times the diameter of the rod. Clean the areas, place bar in hole and fill the hole with Conrep.302 HF to full capacity. The dimensions of anchoring must not be above 5 cm. For bigger anchoring, it is recommended to use Conrep.302 HF-microconcrete. Grouting and Concrete repair Conrep.302 HF can be used for thicknesses up to 10cm. Apply the mortar evenly on the concrete surface where required. Ideal application temperature is between +5°C and + 35°C. Thickness above 10 cm can be practiced depending on the design of the repair job and level of steel reinforcement. Shoring / Soil nailing Conrep.302 HF can be used for grouting the inclined holes in shoring application. Hole diameter must not exceed 20cm, depth of hole will be determined by the structural engineer. Conrep.302 HF high flowability and expansion properties ensure an excellent anchoring / friction with soil/rocks.

PRODUCT BENEFITS

SUBSTRATE PREPARATION The substrate should be dry, free from loose or unsounded pieces, dust, greasy matters or paint. The substrate should be abraded by light brushing, grinding or light sandblasting depending on its quality. When a rough surface is difficult to obtain, Eposil.plus should be used to prime the surface, Conrep.440 PR should be applied while the primer is still tacky, but not before 10 to 20 minutes after primer application.

INSTRUCTIONS FOR USE The product is already delivered in the recommended mixing proportions. Mix the resin (Part A) and the hardener (Part B) manually or with a mechanical low-speed mixer (speed < 300 rpm) in a suitable container until a homogeneous mix is obtained. Then gradually add the filler (3rd component: Part C) to the mixture while mixing thoroughly. The mixing should continue after all the components have been added for approx. 3 minutes to ensure that the product is fully blended and a homogenous mortar is obtained.

APPLICATION METHOD Lining: The mixed epoxy mortar should be placed immediately after mixing. It can be applied by using a steel trowel. The mortar should be firmly compressed on all surfaces to ensure good compaction and adhesion. On vertical and overhead surfaces, avoid applications over 12 mm per layer since the mixed material may exhibit some sagging. In this case it is recommended to apply 2 or 3 layers making sure that the first layer is rough and dried before the application of any successive layer. The setting will occur within 5 hours depending on the temperature. Mixed material may exhibit some sagging. Repair: Apply the mortar with a trowel or by other means on the wall or on the floor. Level it and smoothen it with a trowel or a float. The setting will occur within few hours and its chemical resistance will be fully obtained within 7 to 14 days. After usage, clean tools with xylene. Ideal application temperature is between +5ºC and +35ºC.

PRODUCT BENEFITS

SIZE AND SURFACE FINISH Biflex.PL is supplied in 1 m wide and 10 m length rolls. The surface finish is either sanded or protected with PE film. Biflex.SL has a slated rough surface.

REINFORCEMENT CORE AND COATING MIXTURE Biflex.PL waterproofing membrane is reinforced with 180 grams non woven spunbond polyester reinforcement that gives the membrane dimensional stability and resistance to puncture. It is coated with a specially formulated mixture of SBS modified bitumen which makes the membrane resistant to water, atmospheric agents, and malleable at low temperature while retaining a high softening point. Biflex membranes are resistant to chlorides, sulphates and phosphates found in ground water.

INSTRUCTIONS FOR USE The membrane must first be unrolled and laid down on the area to which it is to be applied. Check the orientation carefully. Adjacent rolls should then be laid, each overlapping the one next to it by 10 cm on the side and 15 cm at the ends. Taking care not to change the orientation of each roll, reverse the process until each has been re-rolled. When laying the roll, the lower surface should be heated with a propane torch, using sweeping left to right movements. This will melt the lower surface of the membrane and allow it to stick to the substrate. Continue this process for each subsequent roll, remembering that the overlaps must be 10 cm for the edges and 15 cm at the ends. When the process is complete, carry out an inspection to ensure total adhesion. When applied in a totally bonded system, a priming coat of Waterproof.prime WB or Waterproof.prime SB should be applied at the rate of 200 – 300 g/m².

APPLICATION TOOLS & EQUIPMENT

The upper surface of the membrane can either You will need a propane gas torch, a gas cylinder, a be covered with a coating of fine sand or with knife for cutting and trimming and a trowel a thin polyethylene film. The bottom surface is with a rounded end. covered with a thin film of polyethylene that is burnt-off during the torching process.

COATING MIXTURE The coating / impregnation mixture used in Biplas.PL/SL waterproofing membrane, which is also the waterproofing agent, is bitumen which has been heavily modified with APP plastomeric thermoplastic resins, stabilizers and antioxidants. This mixture gives the membrane excellent resistance to atmospheric agents and ageing, whilst maintaining shape stability at high temperatures, thus allowing high adhesion strength and making it easy to apply, with consequent saving in time and manpower.

METHOD OF APPLICATION The application of Biplas.PL/SL waterproofing membrane is both easy and quick. Where it is to be laid directly in a one-layer system on concrete, tiles or an existing roofing system, a coat of Waterproof.prime WB or Waterproof.prime SB at the rate of 200-300 g/m² should first be applied. Allow this coating to dry thoroughly. In areas of high humidity we recommend it should be left overnight. As in all other application, the membrane should first be unrolled and positioned correctly on the surface to be treated. Each roll should overlap the adjacent roll by 10 cm. Once the roll has been positioned correctly, the membrane should be rolled up again, taking care not to change its orientation. Using left to right movements, heat the lower surface of the membrane with a propane gas torch. This will cause slight surface melting and adhesion to the substrate. Continue the above method for consecutive rolls remembering overlaps must be 10 cm and end laps 15 cm. Inspection of lap joints must be carried out to ensure total adhesion.

Jointseal PS 1000 GG/PG Two-component polysulphide joint sealant

PRODUCT BENEFITS

MIXING Jointseal.PS 1000 GG/PG • Mix and use one complete unit at a time - do not subdivide • Jointseal.PS 1000 GG/PG is supplied in two part, in separate tins with the curing agent contained in a smaller tube. • Mix for 5 - 10 minutes using a paddle fitted to a 500 RPM electric drill, moving the paddle completely through the mass of the material. The sides and base of the container should be periodically scraped down with a palette knife to ensure all of the curing agent is completely blended with the base compound. • Failure to completely disperse curing agent throughout the base compound will result in uncured sealant. Jointseal.PS 1000 GG/PG should be used immediately once mixed.

APPLICATION • Jointseal.PS 1000 GG/PG is designed to be applied using a sealant gun, but can be applied by trowel if required. • Sealant guns are fitted with conical nozzles which can be cut to suit the joint width. • The sealant should be gunned into the joint using an even trigger pressure, cleaning the nozzle occasionally to avoid contamination. Deep joints should be filled in two or more runs, to prevent air entrapment. • Once the sealant has been applied, a small timber spatula, soaked in soapy water, should be used to compact the sealant into the joints and to tool off to achieve a smooth polished finish. Any masking tape which has been applied should be removed before the sealant cure. • Mixing and application equipment should be cleaned immediately using a tool cleaner, and using rubber gloves to prevent tool cleaner coming into contact with the skin.
