Geomembrane Geotextile

Geotextiles mainly in the following three series: a needle-punched nonwoven geotextile, choose between standard 100g / m2-600g / m2, the main raw material is the use of polyester staple fiber or polypropylene staple fiber by needle punching method, the main Usage is: river, sea, lake embankment slope protection, land reclamation, quay, lock flood control and other projects, is played by returning filtered water and soil conservation and effective way of preventing piping. Second, acupuncture non-woven and PE film composite geotextile, the specifications are a cloth membrane, two cloth one film, a maximum width of 4.2 m main raw material is to use non-woven polyester staple fiber needle, PE film composite made by The main purpose is impermeable for railways, highways, tunnels, subways, airports and other projects. Third, non-woven and woven composite geotextile, a variety of non-woven polypropylene filament woven with complex, non-woven and braided composite plastics for foundation reinforcement, adjust the permeability coefficient on the basis of engineering facilities. Features: light weight, low cost, corrosion resistance, filtration, drainage, separation, and enhance the excellent performance. Uses: Widely used in water conservancy, power, mines, roads and railways geotechnical engineering: l, soil separation filter material; 2, reservoirs, mining beneficiation drainage material, high-rise building foundation drainage material; 3, river dams, slope protection anti-erosion material; 4, railway, highway, airport runway embankment reinforcement material, marshes road reinforcement material; 5, frost, frost insulation materials; 6, asphalt pavement crack material. Geomembrane Description: Geomembrane with impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable material, its performance depends on impervious impermeable plastic film performance. At present, the application of impermeable plastic film at home and abroad, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), tunneling applications as well as design use ECB (ethylene-vinyl acetate modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small, strong extension, the ability to adapt to high deformation, corrosion resistance, low temperature, frost performance.
