Geomembrane manufacturers tell you the basic characteristics of the material impermeable geomembrane with 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), also designed to use the tunnel applications ECB (ethylene-vinyl-modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small sling geomembrane, extension of the strong ability to adapt to high deformation, corrosion resistance, low temperature, frost performance. 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 general characteristics of the soil and EVA geomembrane include physical properties, mechanical properties, chemical properties, thermal properties and durability and so on. Pay more attention to its waterproof geomembrane in engineering applications (impermeable) performance, deformation resistance and durability. Practice has proved that a large number of engineering geomembrane has good impermeability; elastic strain has good ability to withstand various stress conditions and construction work; have good aging ability ponds geomembrane, in water, soil geomembrane durability in particular. There are several points to note in the transport and storage process geomembrane: 1, the use of folding packing transportation aquaculture geomembrane shall not be used with wooden nails to prevent damage in transit; the use of the web transportation, pay attention to prevent damage to the surface of the membrane during loading and unloading. 2, during and after transport geomembrane transported to the site you want to avoid the sun, to prevent the adhesive into pieces and store it in the warehouse, the warehouse as possible in a place accessible to minimize loading times. HDPE geomembrane laying before laying HDPE geomembrane qualified acceptance by the appropriate civil documents. 2. HDPE geomembrane before cutting, should accurately measure its relative size geomembrane, and then press the actual cutting, generally should not be cut by the icon size, should by piece number, a detailed record of the special form. 3. laying of HDPE geomembrane should be sought to weld at least, under the premise of guaranteeing quality, try to save raw materials. But also easy to ensure quality. The seams between the membrane and the membrane lap width is generally not less than 10cm, usually arranged in a direction parallel to the weld maximum slope, that are arranged in the direction of the gradient. 5. At the corner and deformity usually lots should be to minimize the short length of the seam. In addition to special requirements, the slope is greater than 1: 6 slope within slope from the top or the stress concentration range of 1.5 m area, as no welds. 6. HDPE geomembrane laying, you should avoid artificially folds, at lower temperatures, should be taut, paved. 7. HDPE geomembrane after laying is completed, should minimize the membrane surface walking, moving tools, who can cause harm to the object of impermeable membrane, the membrane should not be placed or carried on the film walking, so as to avoid membrane damage caused by the accident.
