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. Features: 1 width, full thickness specifications. 2. Has excellent resistance to environmental stress cracking resistance and excellent chemical resistance. 3. Excellent chemical resistance. 4. With a large temperature range and long life. 5. Use in landfills, tailings storage sites, canal seepage, dam seepage and subway projects. Geomembrane with impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable membrane impermeable material waterproof outlets, 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), also designed to use the tunnel applications ECB (ethylene-vinyl-modified bitumen blend geomembrane) water impermeable membrane, 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 impermeable waterproof membrane manufacturers, generally 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. Hot glue joints, glue, and other methods of custom waterproof lap impermeable membrane, the project design uses 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.
