Geomembrane is blow molding by high molecular polymer such as PE
HDPE geomembrane, LDPE geomembrane, EVA geomembrane
Perfect anti-seepage, high obstruction, high puncture-resistance, excellent performance of chemical erosion resistance, good lasting quality, no pollution, easy to splice and construct.
Highways, irrigation works, lake dam, shore protection project, railways, tunnels, landfill waste site, sea-farming, salt pond, sewage treatment works, golf-links, etc.

Composite geomembrane is a new type of anti-seepage material made by infrared ray heat with geotextile and geomembrane (PE, EVA etc.)
One-textile one-membrane, two-textile one-membrane, N-textile N-membrane.
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.
Anti-seepage, obstruction, reinforce, crack-resistance of irrigation works, environment protection, construction, roads, tunnel etc.
