Geomembrane Introduction:
EltMembrane-GH series of geomembrane is manufactured from High Density Polyethylene resins. The surfaces of both sides are smooth.the products are manufactured by the technology of coextrusion-blown triple layer.
HDPE Geomembrane Performance:
1, Excellent physical and mechanical performance, high tearing resistance;good deformation adaptability, high puncture resistance;
2, High aging resistance, high UV resistance, anti-acid & alkali;
3, Excellent low & high temperature resistance, innocuous, long life span;
4, Perfect water proof performance, seepage and humidity resistance.
HDPE Geomembrane Application:
1,Prevent leakage disposal in landfill or waste water or waste dregs disposing field.
2,River bank, lake dam, mine remainings, reservoir, tunnel. Liquid storage pool(pit, mine)
3,Preventing leakage in subway, basement, tunnel, hole. Anti-salt leskage in roadbed and other groundsill.
4,The plane direction laying of dam, the vertical direction laying for groundsill, used in the construction fence and waste material field.
5,Used in seawater of freshwater feed field.
6,Used in groundsill of road, highway, railway and waterproof layer of swelling clay and wet collapsed loess.
7,Preventing leakage on rooftop
