Hdpe Membrane

HDPE (High Density Poly Ethylene) membrane, a unique composite sheet, comprising of the HDPE backing layer, a pressure-sensitive adhesive membrane, and trafficable weather-resistant protective granular layer. The membrane firmly bonds to the poured concrete preventing ingress or migration of water around the structure. As the mass of the structural concrete increases during the concrete pour, the pressure-sensitive self-adhesive membrane is ‘activated’ and forms a continuous adhesive bond with the concrete poured against it. This results in excellent adhesion through the development of substantial inter-molecular forces.
