HDPE geomembranes have two core functions: impermeability and isolation.

They are mainly used in the following five major areas:

Environmental protection and pollution control: "Leak-proof liners" for landfills, sewage treatment ponds, and hazardous waste disposal sites.

Water conservancy and water saving: "Impermeable linings" for reservoirs, artificial lakes, and irrigation canals.

Agriculture and aquaculture: "Impermeable sealing layers" for fish and shrimp farming ponds and biogas digesters.

Mining and chemical industry: "Isolation barriers" for tailings ponds, heap leaching ponds, and chemical evaporation ponds.

Infrastructure moisture protection: "Waterproof and moisture-proof layers" for basements, tunnels, and roadbeds.
