Sika Proof A

SikaProof A is a fully and mechanically bonded, composite sheet membrane waterproofing system. It consists of an embossed, flexible polyolefin (FPO) membrane laminated with a sealant grid and a non-woven fleece. SikaProof® A is cold-applied and pre-applied, as it is installed without heat or open flames, and before the steel reinforcement is placed and the concrete is poured.
