Texas geomembrane price geomembrane geomembrane professional manufacturers specifications Chen Tel: 13639450809 detailed description of a geomembrane, geomembrane performance geomembrane (composite impermeable membrane) into a cloth membrane and two cloth one film , wide 4-6m, weight 200-1500g / square meter, physical and mechanical properties of tensile, tear, bursting and other indicators of high, the product has high strength, good elongation properties, deformation modulus, acid , anti-corrosion, anti-aging, anti-seepage performance characteristics. To meet the water, municipal, construction, transportation, subways, tunnels, construction of impervious, isolation, reinforcement, crack control reinforcement, civil engineering needs. Due to its selection of polymer materials and the production process adds anti-aging agent, it can be used in unconventional temperature environment. Commonly used in dams, drainage ditch seepage treatment, as well as pollution prevention and waste treatment field. 2, geomembrane geomembrane construction is on one or both sides of the film paste geotextile, geomembrane formation. In the form of a cloth membrane, two cloth one film, two films a cloth. Geotextile as geomembrane layer of protection, protective impermeable layer from damage. To reduce the ultraviolet radiation, increases anti-aging properties, preferably laying buried in France. Construction, the first to use a smaller diameter material leveling sand or clay base surface, and then laying the geomembrane. Geomembrane not stretched too tightly, buried in the soil at both ends of the body part is corrugated, and finally in the shop geomembrane layer of about 10cm over layer of fine sand or clay. Lined with 20-30cm stone (or precast concrete blocks) for the anti-scour protection layer. Construction, should try to avoid a direct hit in the geomembrane stones, the best side to side laying the construction of the protective layer. Geomembrane connection with the surrounding structures should be used bolts and steel batten anchoring, joints brushing emulsified asphalt (thickness 2mm) bonding, to prevent leakage there. Geomembrane seams processing is a key process directly affect seepage effect. Generally joints are: ① lap: lap width should be greater than 15cm; ② heat welding: appropriate for thicker substrates geomembrane weld lap width of not less than 5CM (not recommended for bonding, prolonged water immersion. easy to open plastic, impervious poor results.)
