Four (4) popular types of geomembranes are available for pond liner systems.  These four (4) geomembranes in ALPHABETICAL order are: (1) EPDM, reinforced polyethylene (RPE),  Polypropylene (PP), and (4) Polyvinyl Chloride (PVC). EPDM (Ethylene Propylene Diene Monomer) geomembranes are unreinforced and have been used for the construction of ponds of varying kinds. EPDM geomembranes are made from rubber and can be welded together with tape and primer. EPDM can be reinforced or unreinforced.  RPE geomembranes have a high tensile strength and puncture resistance because they are reinforced. RPE geomembranes also can be welded with heat.  PP geomembranes can be unreinforced or reinforced depending on the application. Reinforced PP geomembranes also have a high tensile strength and puncture resistance because they are reinforced. PVC geomembranes are also unreinforced and have been used successfully for decades in water canals, ponds, and reservoirs. PVC geomembranes can be welded with heat and/or solvents.

At present, we have inport and export rights, and we are the member of Chinese Technical Association on Geosythetics and hss been recognized as a Provincial-level Enterprise Abiding by the Contract, keeping promise for several succsssive years. Besides, we arwarded the titles of Shandong Famous Brand.

Application of geomembrane

Our geomembrane can be widely used in canal, aquaculture, irrigation ponds and remediation liners, 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
