Durability and Economy Compound Geomembrane for Environmental Protection Projects
Product Introduction
Compound geomembrane is an impermeable material made by combining geotechnical fabrics with geomembranes. It uses plastic film as the base material for seepage prevention and is combined with non-woven fabric to form a geotechnical anti-seepage material. It is a commonly used type of geotechnical composite material.
