Geomembrane into a cloth membrane and two cloth one membrane, width 4-6m, weight 200-1500g / square meter, physical and mechanical properties of tensile, tear, bursting and other indicators of high, products with high strength extending better performance, deformation modulus, acid, corrosion resistance, anti-aging, anti-seepage performance characteristics. To meet the water, municipal, construction, transportation, subways, tunnels, construction of impervious, isolation, reinforcement, crack control reinforcement, civil engineering needs. Due to its selection of polymer materials and the production process adds anti-aging agent, it can be used in unconventional temperature environment. Commonly used in dams, drainage ditch seepage treatment, as well as pollution prevention and waste treatment field. The useful life of geomembrane problem, mainly by impermeable impermeable plastic film whether action may be lost, so the useful life of geomembrane sufficient to meet the requirements of the look Dam limit. The protective layer of soil material must use pounding dense, ensure the dry bulk density of 1.5 or more, and feel free to sampling and testing. Backfill protective layer and stone masonry retaining surface, be sure to light up a waterproof membrane impermeable direct avoid crashed geomembrane. In the following professional stone retaining surface water impermeable membrane, the filling should be 100mm thick gravel or gravel cushion to prevent the influence of water level change, storms and other factors while scouring brush soil material protective layer. Dry stone masonry waterproofing take artificial hung paved impermeable membrane, should be closely embedded in solid rock, stone surface layer should be greater than the individual weight 48kg, while HDPE geomembrane geotextile all voids are filled with a small stone. Geomembrane with impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable material, its performance depends on impervious impermeable plastic film performance. At present, the application of impermeable plastic film at home and abroad, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer) impermeable waterproof membrane manufacturers, as well as applications designed to use the tunnel ECB ( ethylene vinyl acetate modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small, strong extension, the ability to adapt to high deformation, corrosion resistance, low temperature, frost performance. When laying, must be made while laying down. Between the film and the film and the film and the substrate surface to be flattened snapping, but not too tight to pull the membrane, usually slightly loose a little, but you can not leave bubbles in the film at the end. Because previous geomembrane relatively thin and very light, after laid in the protective layer is not paved, easily by the wind, so the area should not be laying up big time, the best side to side laying protective cover layer of soil material. Provide information, according to the manufacturer geomembrane width 1.0 ~ 1.9m, 1.9m width of the projects selected to reduce the joint use of materials. Joints with hot sticky, adhesive, overlap and other methods, the project design using adhesive, seam width 50mm. If it is found geomembrane punctured or torn place, be sure to use three times the area of ??damaged adhesive geomembrane good supplement.
