HDPE geomembrane pond liner for mining landfill dam fish pond

HDPE geomembrane ( high density polyethylene geomembrane) use high-quality polyethylene virgin resin, the main component of 97.5% of high density polyethylene, about 2.5% of carbon black, anti - aging agent, antioxidant, uv absorber and stabilizer ; Tai'an Taidong introduced ultra width automatic HDPE antiseepage geomembrane production equipment, all products produced according to the GRI standards and ASTM testing standards. We have completed specifications, smooth surface and textured surface, thickness from 0.10 mm to 4.0mm, width can be up to 10 m, the HDPE geomembrane can completely meet the application requirements of Environmental Sanitation, Water Conservancy, Construction, Municipal Engineering, Landscape, Petrochemical, Mining, Salt, Agriculture, Aquaculture.

Products Details

HDPE geomembrane as a new material, it has excellent anti-seepage, anti-corrosion performance, good chemical stability, and it can be processed according to actual engineering needs. It has been widely used in dike, dam and reservoir anti-seepage of water conservancy projects, as well as in channels, reservoirs, sewage pools, swimming pools, buildings, underground buildings, landfill, environmental engineering, etc. HDPE geomembrane is used as anti-seepage, anti-corrosion, anti-leakage and moisture-proof material. The HDPE geomembrane has different production standard, for example, American GRI GM standard, ASTM test method; and GB standard (China national standard). 1. Easy installation: as long as the pool is dug and leveled, no concrete cushion is needed; 2. Rapid installation: there is no solidification period required for structural concrete; 3. Resistance to foundation deformation: HDPE geomembrane can resist foundation settlement or foundation deformation due to its good fracture elongation; 4. Good effect: this is the biggest characteristic of HDPE geomembrane; 5. Recovery after useing: this is the biggest characteristic of HDPE geotextiles. After use, as long as it is put away and the pool is backfilled, it can be restored to its original state.
