Composite Geomembrane

Descripción

Descripción del producto

Composite geomembranes are made by thermally or adhesively bonding polyethylene (PE) impermeable membranes with needle-punched geotextiles. They combine the impermeability of the membrane with the tensile and protective strength of the geotextile layer. Available in “one fabric one film” or “two fabrics one film” structures.
