sao tome and principe Waterproof HDPE Geomembrane Liner Pond Liner Dam Liner

Geomembranes use plastic movies as anti-seepage substrates, commonly which encompass polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt combo geomembrane) is moreover designed and used.

Product Description

Introduction

HDPE Geomembrane made from polyethylene polymer materials, through blowing or extruding technology, CE/ASTM/GB standards available. Our thickness ranges from 0.2-3mm; smooth, textured or bi-color surfaces available. HDPE Geomembrane main function is to prevent the liquid leakage and gas volatile. It is widely used in lining of pond reservoirs, canal, waste water, landfill, dams, Lakes, fish ponds and many other areas because HDPE Geomembrane is cost effectiveness and resistance against chemical and weather conditions.
By the way, except HDPE Geomembrane, we can also produce LDPE/EVA/PVC/EPDM materials geomembranes.

Applications

1. Prevent leakage disposal in landfills, waste water, or in waste dregs disposing field.
2. Retain river bank, lake dam, mine, reservoir, tunnel. Working as liquid storage pools.
3. Prevent leakage in subway, basement, tunnel. Also, it prevents anti-salt leakage in roadbed, and other projects.
4. The plane and the vertical direction laying of dam and ground sill, LLDPE Geomembrane Liner is used in the construction fence and waste material fields.
5. Used in ground sill of road, highway, railway, and waterproof layer of swelling clay.
6. Prevent leakage on rooftop.
