EVA geomembrane is a copolymer of ethylene - vinyl acetate, has features of good flexibility, elasticity, adhesiveness, weather resistance, environmental stress cracking resistance and the various mechanical indexes were greater than those of ordinary polyethylene. Due to its strong flexibility, its construction is very convenient and the welding effect very good.
The products are widely used in high difficulty lining structure of metro, anti-seepage engineering of the basements, tunnel, water retaining dam, artificial lake and other industrial waterproofing projects
