Composite Geomembrane impermeable geomembrane
Product Introduction
Composite Geomembrane is a non-permeation material, which is compounded with geotechnical fabric and geotechnical film. It is mainly used for permeation proof drainage and reinforcement. Synthetic geotechnical film is divided in to one-cloth with one-film, two-cloth with one-film, multi-cloth with multi-film. Width: 1-6m, Weight: 200-1500g/m2, its physical performance specifications such as tearing resistance and breakage resistance are high. Since high molecule material and anti-aging agent are added in its production technology, it can be used in abnormal temperature environment.
Product Features
It integrates permeation inverse filter and drainage functions, and has various functions such as isolation and reinforcement.It has high synthetic strength, large removal strength and high puncture resistance.It has strong drainage capacity, large friction factor and small expansion factor.It has good aging resistance, wide environmental temperature range and stable quality.
Application Range:
It is widely used in various projects such as water conservation, environmental protection, traffic and tunnel
Products: two-cloth with one-film (there are protective layers on the two sides of the anti soaking geomembrane) anti-soak
One-cloth with one-film (there is a protective layer on the anti soaking geomenbrane)
