Sika® BituSeal T-140 SG

4 mm thick, torch-on sheet waterproofing membrane based on APP modified, reinforced bitumen, with a sand broadcast surface – Flexible to 0°C

Sika® BituSeal T-140 SG is a torch-on sheet waterproofing membrane that is flexible to 0°C. It is based on APP (atactic poly-propylene) modified bitumen, reinforced with polyester non woven fabric. It has a sand broadcast surface and the reverse is faced with a polyethylene film to ease installation works.

Application steps

SUBSTRATE QUALITY

The supporting structure must be of sufficient structural strength to apply all new and existing layers of the waterproofing build-up. When used as a roofing membrane, the complete roof system must be designed and secured against wind uplift loadings. The substrate must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, bitumen, oil, dust and loosely adhering particles.

SUBSTRATE PREPARATION

Use the appropriate Sika® repair material with equipment to achieve the required substrate quality.
