Geomembrane is a kind of polymer as the basic raw materials waterproof barrier. Divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and EVA geomembrane. The main mechanism of the non-permeable plastic film is cut off earth leakage passage farming impermeable membrane, with its greater tensile strength and elongation to withstand water pressure and adapt to dam deformation; and non-woven is a high molecular staple fiber chemical materials, through needle stick or hot forming, high tensile strength and elongation farming impermeable membrane manufacturers, it is combined with plastic film, not only increases the tensile strength and puncture resistance of the plastic film the ability of its useful life made a more grace provisions, such as the former Soviet Union BCH07-74 "embankment dam seepage control structure of polyethylene Notes application" provides polyethylene geomembrane can be used for the useful life of less than 50 years of building. High tensile strength, low elongation, uniform vertical and horizontal deformation, high tear strength, excellent abrasion resistance, resisting strong. Geomembrane raw materials are polyvinyl chloride (PVC), high density polyethylene (HDPE), low density polyethylene (l before DPE), chloroprene rubber (CR), chlorinated polyethylene (CPE), ethylene copolymers (EVA ) The latest farming impermeable membrane, these are polymer (Polymer). Another one is the asphalt product (asphaltieproduet), does not belong to the polymer. Asphalt products previously used in canal seepage, roofing seepage, now only used for roofing Geomembrane into woven geotextiles and nonwoven geotextile. Geomembrane with excellent filtration, isolation, reinforced protective effect, high tensile strength, permeability, high temperature, anti-freeze, anti-aging, corrosion-resistant. Geomembrane connection with the surrounding border. Geomembrane must be closely combined with the surrounding border, the construction can be connected in the foundation and slope excavation anchoring groove, if the foundation is shallow permeable layer of gravel, sand and gravel excavation should be out until the bedrock and then pouring concrete base, The geomembrane fixed in concrete, if the foundation is sticky water impermeable layer, can be deep excavation 2m, 4m wide groove around the anchor, the film is placed in the slot geotextile, geomembrane and compacted clay backfill can be used for floor or crushed stone or gravel slope without containing only a small amount of non-angular gravel channels, libraries plate and relatively gentle slope of the dam face seepage, and designed to reduce surface evaporation stage tanks, water towers, water floating pool cover. Channels and the library can be used for disk impermeable geomembrane gravel gravel soil, earth dam upstream slope protection impervious surface or central impervious core; between road and rail embankment off the foundation and prevent groundwater rise Frothing isolation layer; dry masonry or masonry dam dam seepage barrier; yard waste and venom cesspool of isolation layer very versatile.
