PVC Water Stop Membrane
Product Description
The geomembrane is a waterproof membrane made by polyethylene (PE), PVC and other
geomembranes. After the processes of calendering, spreading and rolling you will get the product.
Application Range
Widely used in the seepageroofing engineerings such as landfill,sewage&waste residue processing plant,dam,tunnel,
building,traffic and environmental protection,etc.
