1.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.

2.Our advantages:

New raw material and the precise formula;
Advanced equipment, perfect production process;
Real-time detection, strict quality control staff;
The packaging is solid to ensure the safety of the goods in delivery.

3.Application:

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.

Construction Method

1. The slope shall be laid in order from top to bottom. Don't pull it too tight.
2. Tow adjacent longitudinal joints should not be in a horizontal line, should bestaggered more than 1m each other.
3. Longitudinal joints should be more than 1.50m away from the dam foot and bending foot, and should be located on the plane.
4. When the slope is laid, the direction of spreading film should be basically parallel to the slope line.
5. The construction, first of all to use small diameter sand or clay levelingbase, and then laid the geomembrane. The geomembrane should not be stretched too tight, and the part of the soil bured at both ends is corrugated. A transitional layer of about 10cm is laid on the geomembrane with sand or clay.
