SikaProof® A is a fully and permanently bonded, self-adhesive, composite sheet membrane waterproofing system for
reinforced concrete structures. It consists of an embossed polyolefin (FPO) based 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 openflames, and before the steel reinforcement is fixed and the concrete is poured.
