Geotextile geomembrane should meet the engineering requirements. First introduce geotextile: Geotextile provisions stated new types of construction materials for building projects, by wire or staple fiber through the same equipment layout of the mesh and then by acupuncture and other technology to make the fibers intertwined with each other from the entanglement, normalizing fabric so that the fabric is soft, plump ., thick, stiff and thickness meets the requirements. according to short silk spinning silk or spinning geotextile or geotextile tensile strength higher than the wiring soft short silk fiber with tear resistance . major role: Filtration, drainage, reinforcement action specification 100 grams 800 grams per square meter per square meter main material of polyester fiber having excellent water permeability, filtration, durability and ability to adapt with a deformable surface drainage capacity geomembrane plastic film as a impermeable substrate and spinning cloth composite geotextile material impermeable membrane impermeable fabric two cloth membrane performance depends on impermeable plastic film performance geomembrane kinds of flexible high polymer material proportion of the basic raw material waterproof barrier materials than the extension of the strong deformation capacity to adapt to the high corrosion resistance low frost resistance
