Geomembranes are a kind of geosynthetic material. They are impermeable membranes used widely as cut-offs and liners. Until recent years, geomembranes were used mostly as canal and pond liners.

Applications
1. Environmental protection and environmental sanitation (for example, living landfill yard, sewage treatment plant, power plant adjusting tank, industrial and hospital solid waste, etc.).
2. Water conservancy (for example, anti-seepage, leakage blockage and reinforcement of river, lake and reservoir dikes and banks, anti-seepage of canal, vertical central wall, side slope, etc.).
3. Municipal projects (underground project of subway and structure, anti-seepage of plantation roof and roof garden, lining of sewage pipe, etc.).
4. Landscape garden (man-made lake, river way, cistern, bottom lining and side slope of pool in golf course, waterproof and anti-seepage of greening lawn, etc.).
5. Petrochemical industry (anti-seepage of oil tank of chemical plant, oil refinery and filling station, lining of chemical reaction tank and sedimentation tank, etc.).
6. Mine industry (bottom lining and anti-seepage of washing and selecting tank, piling and soaking tank, ash yard, dissolution tank, pile yard and tailing, etc.).
7. Traffic facilities (reinforcement of road foundation and anti-seepage of subway and culvert).
8. Agriculture (anti-seepage of ditch, channel, reservoir, drinking water tank, pool and irrigation system).
9. Aquaculture industry (lining of intensive and plant type cultivation tank, fish pound and shrimp pool, side slope of sea cucumber ring, etc.).
10. Salt industry (crystal tank of salt field, tarpaulin cover of halogenation tank, salt film, plastic tarpaulin cover of salt tank).
