Geomembranes are the impermeable geosynthetic products that have better physical, mechanical and chemical resistance properties protecting environment and water resources. Compared with traditional concrete, asphalt and compacted clay, geomembranes have proven to be far more effective, safe economic and fast deployment. They are widely used as canal, aquaculture, irrigation ponds and remediation liners, other lining applications include landfills, wastewater treatment lagoons, oil and gas exploration, etc.

Geomembranes, also known as waterproof geomembranes, is a type of impermeable membrane, usually made of primary resins such as high density polyethylene (HDPE). They have excellent impermeability and chemical resistance, can effectively prevent water and other liquids from penetrating into the soil, and protect groundwater and surface water resources. For this reason, they are commonly used in projects such as landfills, chemical plants, mines and reservoirs as seepage barriers.

At present, HDPE geomembrane anti-seepage structure design is adopted in China's domestic sewage treatment plants and petrochemical industries and some other fields. HDPE geomembrane has the advantages of high strength, good ductility, strong anti-seepage ability and good chemical stability.
In recent years, with the improvement of environmental protection regulations and the improvement of environmental protection requirements for construction projects, the environmental protection anti-seepage problems of mine tailings ponds have become increasingly prominent.
The HDPE geomembrane produced by our company can fully meet the integration of fermentation and gas storage in biogas digesters. The whole oxidation pond is fully enclosed by the anti-seepage material of HDPE geomembrane. The construction is simple, the construction cost is low, the sealing performance is good, and the use time is long. The HDPE geomembrane has strong anti-aging and anti-corrosion properties and good anti-seepage effect.
