Applications

Landfill Liners

2mm HDPE geomembrane serves as primary and secondary liners in municipal solid waste landfills, hazardous waste containment facilities, and industrial waste disposal sites. Its superior impermeability prevents leachate migration, protecting groundwater from contamination. The material's chemical resistance ensures long-term performance even when exposed to aggressive landfill leachates.

Used in sewage treatment plants, regulating tanks, and industrial wastewater containment ponds. The geomembrane prevents seepage of untreated wastewater into soil and groundwater, meeting environmental protection regulations.

Mining Industry

Serves as containment liners for mining tailings ponds, heap leach pads, and processing facilities. The geomembrane prevents the migration of toxic chemicals and heavy metals into the environment, protecting soil and groundwater quality.

Applied as anti-seepage lining materials in reservoirs, dams, and canals to minimize water loss through seepage. The 2mm thickness provides sufficient strength to withstand water pressure and mechanical stresses.
