SikaBit W-15 | Waterproofing | SIKA Products Selangor

SikaBit® W-15 is a high-performance, modified bitumen waterproofing membrane specifically designed for wet-applied installation in non-exposed environments. Unlike traditional membranes that require a bone-dry surface, the W-15 is engineered to be applied directly onto wet substrates using a cement slurry bond.

This unique application method ensures a full-surface bond that eliminates the risk of water underflow (water tracking between the membrane and the structure). With its superior crack-bridging abilities and high resistance to punctures, tearing, and chemical corrosion, it provides a reliable, long-term subterranean shield for critical infrastructure.
