Geomembrane liners is also called impervious membrane. With geotechnical cloth as the conduct water layer, high polymer plastic film as the impervious layer, after rolling, hot melting and coating into composite geotechnical anti seepage material. Its thickness is 0.2 mm - 3 mm, in which the thickness of 0.8 mm above is also called geomembrane. The impervious performance of the geotechnical membrane is mainly depend on the impervious performance of the plastic film. Geomembrane liners' rolling, hot melting and coating production process not only maintain its good mechanical properties, but also make the thickness of the composite product film uniform.

What's more, with the advantage of high peeling strength, it avoids stomatal or sand holes formed on the plastic film, greatly improve the anti permeability of the film. The film surface adopts embossing process, increase the friction coefficient of the film, improve the stability of the seepage control project. And at the same time, it is also convenient for construction, so the application field of geomembrane liners is very extensive like, environmental protection engineering, hydraulic engineering, municipal engineering, petrochemical industry, mining industry, agriculture, aquaculture, salt industry, subgrade engineering and many other places.

eomembrane liners technology index (national standard GB/T17643-1998)

According to the material, geomembrane liners can be divided into: PVC geomembrane liners, HDPE geomembrane liners, LDPE geomembrane liners, EVA geomembrane liners and ECB geomembrane liners, so the technical indicators are also based on a variety of materials to set.

Features:

Wide width and less seam: The width can be up to six meters, compared with other similar narrow width products, it reduces the seams, the cost of the project and shorten the construction period. At the same time, it also reduces the hidden danger that caused by improper joint seam processing.

Low cost and high efficiency: Compared with the traditional cloth and membrane separation, the use of composite geomembrane can improve the use effect, save more project time, reduce the cost of the project, the comprehensive benefit is obvious.

Excellent aging resistance: Using buried laying can have longer service life.

Good chemical stability: Water pressure resistance, corrosion resistance, high strength, wear resistance, low temperature resistance, non-toxic, good plane surface drainage function and good seepage control effect.

Good thermal insulation property: With unique thermal insulation, moisture, anti frost, anti freezing effect.

Applications:

Environmental protection and environmental sanitation: living landfill yard, sewage treatment plant, toxic and hazardous disposal site, dangerous goods warehouse, power plant adjusting tank, industrial and hospital solid waste, buildings and blast landfill waterproof and leakage proof.

Water conservancy engineering: anti-seepage, leakage blockage and reinforcement of river, lake and reservoir dikes and banks, anti-seepage of canal, vertical central wall, side slope, etc.

Municipal projects: underground project of subway and structure, anti-seepage of plantation roof and roof garden, lining of sewage pipe, etc.

Landscape garden: man-made lake, river way, cistern, bottom lining and side slope of pool in golf course, greening lawn waterproof and anti-seepage, etc.

Petrochemical industry: anti-seepage of oil tank of chemical plant, oil refinery and filling station, lining of chemical reaction tank and sedimentation tank, etc.

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.

Agriculture: anti-seepage of ditch, channel, reservoir, drinking water tank, pool and irrigation system.

Aquaculture industry: lining of intensive and plant type cultivation tank, fish pound and shrimp pool, side slope of sea cucumber ring, etc.

Salt industry: crystal tank of salt field, tarpaulin cover of halogenation tank, salt film, plastic tarpaulin cover of salt tank.

Traffic facilities: reinforcement of road foundation and anti-seepage of subway and culvert.
