PVC Waterproof Membranes

Product Description

Products Description

The PVC waterproofing rolls formulas are based upon polyvinyl chloride resin with other assistants added to provide flexibility and stability such as antioxidant, absorbent of ultraviolet light, plasticizer and plastic filling agent.

Products Specification

Divided by the product composition:
homogeneous non-composite membranes(code H),
with fiber composite backing sheet(code L),
fabric reinforced sheet(code P),
glass fiber reinforced membrane within(code G),
glass fibers increased with fiber composite backing sheet(code GL)
Width: 1-2.0m Thickness: 1.2mm 1.5mm 1.8mm 2.0mm

Application Range

PVC membranes form 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.
