Composite geomembrane has excellent filtration, drainage, barrier, reinforcement, anti-seepage and protection effects. It has the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, antifreeze, aging resistance and corrosion resistance. The HDPE geomembrane is called "high-density polyethylene film", which has excellent environmental stress cracking resistance, low temperature resistance, anti-aging and corrosion resistance, and large operating temperature scale (-60--+60) and long application. Life (50 years).It can be widely used in railway, highway, sports hall, dike, hydraulic construction, tunnel, coastal beach, reclamation, environmental protection and other projects. Geomembrane is a product made of polyethylene heated and knead, which has a good anti-seepage function and anti-corrosion function.Its excellent elasticity and deformation can make it very suitable for swelling or shortening the base surface, which can effectively overcome the uneven settlement of the base surface. The water vapor permeability coefficient K<=1.0*10-13g.cm/c cm2.s.pa Therefore, geomembrane liner has a very serious effect on earth and stone seepage prevention.Generally, one side of the geomembrane is a large pore rockfill body, and the other side is a soil to be maintained, and a geomembrane with a filtering effect is sandwiched between the two.When the water flows from the maintained soil from right to left into the rockfill body, part of the fine soil particles will be carried by the water into the rockfill body. The surface of the impermeable membrane on the side of the soil to be maintained is adjacent. http://www.wslgeosynthetics.com/product-gcl-ah-geosynthetic-clay-liners-22757.html
