Geomembrane

The geomembrane uses plastic film as the anti-seepage base material, and is a geotechnical anti-seepage material compounded with non-woven fabrics. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. Plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified asphalt copolymer) is also designed for tunnel applications. They are a kind of polymer chemical flexible material with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance.
