Application of Geomembrane
Geomembrane can be widely used for canal, aquaculture, irrigation ponds and remediation liners, other liner applications include landfills, waste water treatment lagoons, oil and gas exploration, power plants, etc.
1. Environmental protection, environmental hygiene (such as garbage landfill site, treatment of sewage, containment of poisonous or harmful wastes, hazardous warehouse, industry wastes, construction & explosive rubbish, etc)
2. Water conservancy (such as waterproofing, stopping up leak, reinforcement for lake, river, channels, tunnels, dams and reservoirs; vertical wall with core, slope protection, etc)
3. Municipal engineering (expressway, subway, underground engineering of building; and liner of roof pool, roof garden's waterproofing, sewage channel, etc)
4. Garden (backing & slope protection of artificial lake, pool, golf course's pond)
5. Petrochemicals (liner secondary lining of chemical reeaction tank and deposit tank from chemical plant & refinery; seepage control of oil tank from gas station)
6. Mining (backing seepage of washing pond, heap leaching pond, ashery, dissolved pond, deposit pond from the stack and tailing)
7. Traffic facilities (highway foundation reinforcement, culvert stopping up leak)
8. Agriculture (stolling up leak for reservoirs, drinking pools, storage ponds and irrigation system)
9. Aquaculture industry (seepage control for sea cucumber circle's slope protection, liner of fish pool & shrimp pond)
10. Seepage, corrosion, leaks control & reinforcement for other facility, leachate collection
11. Temporary container structure, prefabrication of special parts
