HDPE geomembrane is one of the geosynthetic materials, the application of geomembrane originated in the 1950s, geomembrane is one of the national Eighth Five-Year plan, HDPE geomembrane is a waterproof barrier material produced from (middle) high-density polyethylene resin. (geomembrane with a density of 0.94g/cm3 or above).
HDPE geomembrane is mainly used in landfill, sewage waste treatment, water conservancy, agriculture, transportation, high-speed rail, tunnel, airport, airport, building, landscape and other anti-leakage gasket engineering.
Specification of construction scheme:
Geomembrane in the transport process do not drag, hard drag, to avoid sharp injury.
1, should extend from the bottom to the top, do not pull too tight, should leave 1.50% of the rest, in order to prepare for local subsidence stretching. Considering the actual situation of this project, the slope is laid from top to bottom;
2. The longitudinal joint of the two adjacent pieces should not be on a horizontal line, and should be staggered by more than 1m;
3. The longitudinal joint should be more than 1.50m away from the foot of the dam and the bending foot, and should be located on the plane;
4, the first slope rear field bottom;
5. When laying the slope, the direction of film development should be basically parallel to the large slope line.

1, does not contain chemical additives, also does not undergo heat treatment, is an environmentally friendly building material.
2,  It has good mechanical properties, good water permeability, corrosion resistance and aging resistance.
3, with strong resistance to burial, corrosion resistance structure fluffy, with good drainage performance.
4, has a good friction coefficient and tensile strength, with geotechnical reinforcement performance.
5, with isolation, filtration, drainage, protection, stability, strengthening and other functions.
6, can adapt to the uneven base, can resist the construction of external force damage, creep small.
7, the overall continuity is good, light weight, convenient construction.
8,  It is a permeable material, so it has good filtration isolation function and strong anti-puncture ability, so it has good protection performance.
