The core application of composite geomembranes is to meet the combined needs of engineering projects requiring seepage prevention, drainage, reinforcement, and isolation.

Water Conservancy and Environmental Protection Engineering Seepage Prevention: Used as lining systems for artificial lakes, reservoirs, rivers, sewage treatment plants, and landfills. The geomembrane provides seepage prevention, while the geotextile protects the membrane and facilitates drainage.

Transportation Infrastructure Reinforcement and Drainage:Used in the subgrade of highways, railways, and airport runways. It serves to isolate soil layers, prevent frost heaving, provide reinforcement, and facilitate lateral drainage.

Civil Engineering Seepage Prevention and Protection:Used as a seepage prevention and drainage layer in tunnels, underground engineering projects, and roof gardens, or as a seepage prevention and filter structure within earth-rock dams and retaining walls.
