Proofex GP is a cold‑applied, self‑adhesive sheet membrane that incorporates a polymer‑modified bitumen layer. It is intended for continuous waterproofing of building and civil‑engineering structures such as basements, tunnels, podiums and covered roofs, and is applied to primed concrete substrates. The membrane offers good adhesion to primed surfaces and provides a fast, puncture‑resistant waterproof barrier.
