Wrimco SBS waterproof membrane provides excellent puncture resistance and its lower co-efficient of expansion produces lower strain on the membrane. This is very important in
Australia where high daytime temperatures and rapid night-time cooling as well as thermal-shock (e.g. sudden downpours on hot decks) are both common.
Accelerated tests indicate a life expectancy in excess of 30 years and its track record in
Australia already exceeds 24 years. The factory-applied ceramic granules offer a non-skid surface that provides complete UV protection.
Superior adhesion, greater elasticity, fatigue resistance and high temperature flow resistance
SBS waterproof membrane is elastomeric. This gives it rubber-like properties including excellent elongation and recovery and an extremely long fatigue life. As a result, SBS membrane can be fully bonded to the substrate, which means that water is prevented from tracking. APP, however, is plastic or plastomeric wax which means it is flexible but not elastic and therefore lacks the ability to return to its original shape after very few cycles.
SBS waterproof membrane is a thermoplastic rubber which means that it contains two distinct polymer blocks, thermoplastic styrene and butadiene. Styrene gives SBS membrane its high tensile strength & excellent flow resistance at high temperatures. Butadiene imparts excellent elasticity, fatigue resistance & low-temperature flexibility.
Easier to detail
SBS waterproof membrane has a lower softening point than APP. Lower temperatures means it is easier to detail in general and especially in drains and around PVC pipes. Sound detailing is the essential requirement for trouble-free application.
The lower softening point of SBS membrane (110C -120C) requires less propane to weld it to the substrate making installation is therefore faster, less expensive and easier. Finger moulding around rigid PVC (which decomposes at about 120C) is also possible without damaging either ones hands or the PVC.
Superior appearance maintained
Factory-applied granules have a superior "grab" on SBS waterproof membrane. The elasticity of SBS waterproof membrane results in less marring of the membrane surface. The integral design features provided by the factory-applied mineral finish are maintained for longer periods.
Material consistency
SBS waterproof membrane is a chemically engineered product which withstands movement
SBS waterproof membrane is elastomeric, not plastic or plastomeric, and is therefore capable of being fully bonded which prevents water tracking and makes it less likely to be damaged during construction.
Environmentally sound
SBS waterproof membrane is a pure hydrocarbon and so decomposes in landfill or burns without noxious by-products. In contrast, plasticised PVC contains chloride and oxygen so it decomposes in landfill producing dioxins or burns to give off hydrochloric acid.
The inclined driveway which had torched applied Wrimco SBS Granules applied. The Granule membrane provided a non-slip surface for construction activities which lasted several weeks before a topping screed with stones was applied. The 1mm ceramic chips resulted in an excellent bond for the topping, also
the application of the Wrimco SBS waterproof membrane before the curved glass was installed to the top of the lift shaft. This system is often employed as the method of application provides such an excellent waterproof bond when they are welded together
Torch applying Wrimco SBS waterproofing membrane as a flashing for an external brick wall. Since the elastomeric SBS membrane is fully bonded, there is no possibility of the water tracking as there is with conventional metal flashings which simply overlap and are not bonded to the substrate.
