Description:

HDPE geomembranes are a kind of large molecule (macromolecule) polymer as the basic raw material composed of waterproof and cut-offs(insulation & separation) geosynthetic material.

 

 

Properties:

high strength, low permeability, chemical corrosion resistance, ultraviolet & sun exposure resistance, oxidation resistance, weather resistance, antimicrobial, erosion resistance.

 

 

Application industry or engineering & usage:

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 reserviors; 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 reaction 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(stopping up leak for reserviors, drinking pools, storage ponds and irrigation system)

9.   aquiculture 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
