can be used as two or single layer waterproofing systems for retaining walls, lift pits and water storage or detention tanks (especially blockwork); planters (600mm or wider) and landscaped or grassed areas; terraces, decks, podiums, fish tanks and water features; roofs where insulation (IRMA roof system) or a concrete topping is to be applied; green roofs and basement walls. Recommended for wet area floors on FC or plywood in timber structures and for expansion joints.
can be used as two or single layer waterproofing systems for external areas exposed to UV such as parapet walls and especially membrane roofs (concrete or plywood) or as a second layer cap sheet. It is recommended for waterproofing decks with seated pavers due to its fire resistance.
can be designed for use as the base or first ply in a high performance two-ply modified bitumen system, or as a single ply when not exposed, and for fillets and detailing. Main applications are for tanking, balconies and roofing and for waterproofing of planters.
SBS Sanded waterproofing membrane3.5mm
has one side sanded so it is used where adhesion of a concrete topping is desired such as tanking the floor of a basement below the water table or for direct stick tiles.
is an elastoplastomeric polymer-bitumen waterproofing membrane, with an anti root additive, reinforced with a 'non-woven' single strand spunbond polyester fabric for protecting roof gardens, sunken works and gravel covered roofs. The anti root properties are obtained by adding phenoxi fatty acid ester, a specific anti root agent, to the polymer-bitumen compound.

Since Wrimco SBS is so versatile, it can be very well used in a variety of applications, especially membrane roofs.
Wrimco SBS torch applied to the top deck of a block of luxury flats overlooking Manly beach. This will be subsequently tiled.
The elastic properties and long life of the Canadian manufactured SBS make it an ideal choice for decks over habitable rooms. Being strongly reinforced with 180gsm of non woven Polyester (NWP) and exhibiting excellent adhesion, it will withstand normal construction activities but if it is damaged, it is easily repaired.
Wrimco SBS waterproofing membrane being torched applied to the retaining wall. Wrimco PB4 protection board was then spot torched to the membrane. By melting the surface of the SBS, the need for expensive contact adhesives is eliminated. Once the PB4 is pressed against the surface (molten SBS bitumen is an excellent adhesive), there is complete attachment
The 1mm ceramic chips factory applied are firmly adhered to the Canadian manufactured SBS. The granules cannot be scratched off with a finger nail as is the case with all other membranes with a mineral finish. This is because of the outstanding adhesion of Wrimco SBS membrane due in large measure to their quality control, the Alaskan bitumen used and the high SBS content.
The membrane being torched as a vertical strip in the corner. The "no nails" PACTIV 6.4mm PB4 protection board will be subsequently spot torched to the waterproof membrane.
Superior adhesion, greater elasticity, fatigue resistance and high temperature flow resistance. SBS 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. SBS 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.

This photo shows a membrane roof looking east that is waterproofed with Wrimco SB Granules membrane system. There are no joints that can be seen since width was less than 8m (the length of a roll), and laying was started at the low point so the selvedge is covered when looking in that direction.
The 20 litre pail of Wrimco SBS primer can be seen next to the propane gas bottle which was used for torching the SBS waterproofing membrane.
This photo shows an exposed membrane roof of a private house being waterproofed with Wrimco SBS Granules membrane. The balustrade was first removed in sections and then re-bolted and sealed to achieve a good appearance. There were 75mm laps but fortunately the width was less than 8m, the length of the roll, so there was no need for additional laps.
