EVA waterproofing membrane is a polymer material made from polyethylene modified with ethylene-vinyl acetate copolymer, thermally bonded to a geotextile fabric. It offers excellent impermeability, high tensile and tear resistance, and easy weldability. The geotextile layer provides drainage and cushioning protection, while integrated lifting straps ensure convenient installation.
