Textured Geomembrane
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 description
Textured HDPE Geomembrane is a new type of seepage control material, HDPE geomembrane with single texture and double texture increases 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.
