Reinforced PVC waterproof membrane with polyester

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 a PVC waterproofing membrane is a highly-engineered,new-type membrane manufactured using polyvinyl chloride as main materials and added other chemicals such as anti-oxidant,anti-UV materials to make it flexible,stable and UV-resistant. 

Product Features
