PVC Waterproofing Materials for Concrete Roof
Product Information
The PVC waterproofing rolls formulas are based upon polyvinyl chloride resin with other assistants added to provide flexibility and stability such as anti-oxidant, absorbent of ultraviolet light, plasticizer and plastic filling agent.
Product Features
Good combination of high elasticity and tensile strength. Fine resistance to static electricity. Excellent resistance to ageing / weathering.
Application Range
Reinforced PVC waterproof membrane forms an effective barrier to liquid water or water vapor in the roof construction for industrial and civil engineering, underground engineering such as subway & tunnel, water conservancy such as water pools & ditch, shelter, grain depot, land filling, dyke, sewage treatment and basement.
Construction Method
construction is convenient. Mechanical fixation, heat sealing, cold viscosity and other methods.
