Composite Geomembrane

Product principle

Composite geomembrane is a new type of anti-seepage material made by infrared ray heat with geotextile and geomembrane (PE, EVA etc.)

Product classification

One-textile one-membrane, two-textile one-membrane, N-textile N-membrane.

Product performance:

High puncture-resistance, high friction coefficient, perfect extend, high deformation modulus, excellent performance of chemical erosion resistance, good aging-resistance, good anti-seepage, no influence by climate.

Product main use

Anti-seepage, obstruction, reinforce, crack-resistance of irrigation works, environment protection, construction, roads, tunnel etc.
