Product Description
Rough Surface Geomembrane
Rough HDPE geomembrane is a new type of seepage control material, single roughness, double roughness and other HDPE geomembrane to increase the coefficient of friction, anti-slip function, more suitable for steep slopes and vertical seepage control, to improve the stability of the project.HDPE geomembrane has excellent temperature adaptability, weldability, weather resistance and good aging resistance, chemical corrosion resistance, resistance to environmental stress cracking performance and resistance to poking through performance. Therefore, it is especially suitable for underground engineering, mining engineering, landfill, sewage or waste residue treatment site as anti-seepage material.
Product Performance
Tensile, tear resistance, top breaking and other physical and mechanical properties of the index is high, the product has high strength, better extension properties, deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, seepage control performance is good. Can meet the water conservancy, municipal, construction, transportation, subway, tunnel, engineering construction of seepage control, isolation, reinforcement, crack prevention and reinforcement of civil engineering needs. Commonly used in embankment dams, drainage ditches seepage control treatment, as well as anti-pollution treatment of waste sites.
Product Use
1, landfill, sewage or slag treatment seepage control.
2, river embankment, lake dam, tailings dam, sewage dam and reservoir, channel, liquid storage pond (pit, mine).
3, subway, basement and tunnel, tunnel seepage control lining.
4, roadbed and other foundation salt seepage control.
5, embankment, dam front horizontal seepage control cover, foundation vertical seepage control layer, construction cofferdam, waste yard.
6 seawater, freshwater farms.
7, roads, highways, railroads, foundations, expansion of soil and waterproof layer of humid loess.
8, Roof seepage control.
