Green Sanjiang impermeable geomembrane coefficient -HDPE ordinary waterproof material impermeable membrane has unmatched impermeable geomembrane manufacturer wholesale Shandong effect, HDPE impermeable membrane has a tensile mechanical properties, excellent flexibility and deformation capability makes it ideal for expansion or contraction of the base surface Shandong geomembrane manufacturer direct, impermeable membrane can effectively overcome the uneven settlement of the base surface, water vapor permeability coefficient K <= 1.0 * 10-13g.cm / c cm2.s .pa. Because of tensile strength, high impact strength, anti-infiltration, acid, heat, weather, wear-resistant properties, Geomembrane in coastal areas get a lot of applications in the construction industry. But also in the river dams, reservoirs, water tunnels, highways, railways, airports, underground, underwater and other projects widely used. Geomembrane modern materials has become an important national economic construction. And information about Geomembrane production technology.
