High-density polyethylene waterproofing membrane uses high-quality polyethylene virgin resin as raw material, the main component is 0.965g/cm high-density polyethylene, about 2.5% carbon black, anti-aging agent, antioxidant, UV absorber, stabilizer and other auxiliary materials, using the most advanced fully automatic production equipment in the world, made by three-layer co-extrusion technology, all products are produced according to national standards, with complete specifications, which can meet the application requirements of environmental protection, sanitation, water conservancy, construction, municipal engineering, gardening, landscape, petrochemical, mining, salt industry, agriculture, aquaculture, etc.

Material characteristics

1. Excellent resistance to environmental stress cracking. 2. Large operating temperature range and long service life.

3. Non-toxic and harmless, harmless to the human body, does not pollute the environment, and is widely used in drinking water projects abroad.

Scope of application

Environmental protection and sanitation engineering: such as domestic waste landfills, sewage treatment, toxic and hazardous substances treatment sites, dangerous goods warehouses, industrial waste, construction and blasting waste, etc.; water conservancy and civil engineering: anti-seepage, plugging and reinforcement of river, lake and reservoir dams, anti-seepage of canals, slope protection, etc.; municipal engineering: subways, underground projects and rooftop reservoirs of buildings, anti-seepage of roof gardens, lining of sewage channels, etc.; gardening, artificial lakes, ponds, golf courses, pond bottom lining, slope protection, etc.; petrochemical: chemical plants, refineries, gas stations, oil tank anti-seepage, chemical reaction tanks, sedimentation tank linings, secondary linings; mining: heap leaching tanks, ash piles, dissolution tanks, sedimentation tanks, yards, low lining anti-seepage of tailings, etc.; transportation facilities engineering: foundation reinforcement of highways , anti-seepage of culverts; agriculture: anti-seepage of reservoirs, drinking water pools, water storage ponds, irrigation systems; aquaculture: lining of fish ponds, shrimp ponds, etc....

Construction method

The polyethylene anti-seepage membrane installation and construction should be appropriately pre-released by 2%-5% according to the specific site conditions and the climate conditions at that time; the surface of the installation base should be compacted and leveled, and sharp objects such as tree roots and stones should be removed; the positive and negative corners of the base should be rounded, and the radius of the fillet should be ¡Ý50mm; the surface of the welding seam must be cleaned; the welding seam needs to be installed in a staggered manner to avoid cross welding seams, and T-type installation and laying can be adopted; the side ditch anchoring and landfilling method or the pressure strip sealing installation is adopted; the welding construction adopts double-track hot melt, single-track hot melt, and extrusion type welding rod welding technology; the seam overlap width is 100mm.
