LOGICBASE P-ST

FPO/TPA synthetic waterproofing membrane with structured surface for two-layer underground waterproofing systems

USEFUL

Non-reinforced synthetic waterproofing membrane produced by co-extruding a uniform highly flexible elastomerised polyolefin alloy.

It is used for waterproofing tunnels, foundations, underground parts of buildings and structures as a second layer in double-layer waterproofing systems with vacuum quality control. A specially textured surface of the material prevents two membranes of a double-layer waterproofing system from sticking together during the vacuum quality control. It is not UV resistant.

Fields of application

  • LOGICBASE P-ST membrane is designed for application as a second layer in two-layer waterproofing systems of tunnels, foundations, retaining walls.
