Product Description
Introduction:
HDPE geomembrane, also known as impervious film, its thickness is around 0.2-3mm. HDPE geomembrane with thickness of 0.8mm or more, is also known as waterproof board. It is a kind of waterproof barrier type material made up of high quality polyethylene native resin. Its main components are 97.5% high-density polyethylene, about 2.5% carbon black, anti-aging agent, antioxidant, uv absorbent, stabilizer and other materials. It's widely used in many engineering facilities to prevent water loss, such as landfill, sewage treatment plant, reservoir dam, roof garden, sedimentation tank, river, green lawn, gas station oil storage tank, tailings, culverts, ponds, salt crystallizing pool.

Application Scenarios
Widely used in landfill, sewage treatment plant, reservoir dam, roof garden, sedimentation tank, river, green lawn, gas station oil storage tank, tailings, culverts, ponds, salt crystallizing pool.
1. Ordinary water plant foundation laying, water pressure is small, generally 0.3mm thickness of geomembrane can meet the needs;
2. Rock dam and other rock impervious laying, aquaculture impervious, their imperviousness does not need to be too strong, generally 0.3mm-0.5mm can meet its needs;
3. Landfill, sewage treatment plants, seepage prevention requirements are higher, we can choose 0.4-0.7mm HDPE geomembrane;
4.Chemical plants, oil refineries, oil storage tank seepage prevention, strict environmental requirements, high impermeability requirements, we can choose about 1mm geomembrane.
