Geomembrane
Products Description
Geomembrane is polyethylene and other polymer materials blow molding, according to the production of raw materials can be divided into low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and EVA geomembrane and other products such as high strength, aging resistance, good welding performance, convenient construction.It is mainly used for seepage prevention projects of channels, sewage treatment ponds, wharf projects, river dike reservoirs, lake DAMS, subways, landfill sites, etc.
