Basically, many anti-seepage works will use smooth geomembrane. Such as aquaculture, sewage treatment, reservoirs, reservoirs, artificial lakes, seepage prevention, biogas digesters, landfills and other projects. And like textured geomembrane, because the surface is rough, so as to increase friction, so rough surface geomembrane is generally suitable for seepage prevention work on slopes, especially for larger slopes, like garbage. Landfills, tailings dams, etc.
