JH-W100 Wet-Applied/Pre-laid Applied Polyester Waterproof Membrane consists of high-qualit bitumen, active agent, tackifying resin and the polyester cloth, etc. Which allows the membranes and the base surface to stick together completely like "skin type" waterproof performance.
1, The membrane has good root resistant, tear resistant and abrasive resistant property witht the polyester cloth as its reinforcement core.
2, It can effectively prevent water or steam from getting inside of the structure.
3, After paving of pre-laid membranes, concrete and steel bars can be constructed onn them without the protection layer.
4, It's allowed to pave the membrane on humid base surfaces (no visible water) using wet-laid method without obvious effect of rain, which shortens the working period.
5, The membrane has high tensile strength and good elongation on the base surface.
6, No dripping at high temperature and no cracks at low temperature.
7, Long-time stickness assures no fall-off or any leakage between the membrane and the base surface.
8, The construction is convenient, safe and evironmental friendly without fire and solvent volatilization.
Civil and industiral construction such as basements, side walls, roofs, swimming pools, tunnels and subways, etc.
