Geotextiles can be divided into two categories, namely the impervious geotextile and permeable geotextile. Geomembranes and impervious geotextiles can be used to prevent emission of ground water caused by capillarity. Geotextiles are porous to liquid but soil can't go through them. For example, they can be used on the surface of supporting sewers of high slopes.
Geogrids can be used to reinforce the soil mass and improve the integrity just like the reinforcing bar in concrete. Geotextiles can be used in seepage control engineering. I have place the multilayer non-woven geotextiles and geomembranes on the rubbish dam and anchoring platform of a refuse landfill.
There are some tips about geotextiles. Geotextiles can be divided into two categories, namely the impervious geotextile and permeable geotextile. Geomembranes and impervious geotextiles can be used to prevent emission of the ground water caused by capillarity.
Geotextiles are porous to liquid but soil can't go through them. For example, they are used on the surface of supporting sewers of high slopes and in the roadbeds above water level (water in roadbeds can freely diffuse through the permeable geotextile just as in the roadbed blind ditches).
Geotextiles are used to prevent seepage.
Geogrids are excellent geosynthetics used to reinforce roadbeds and soft grounds. Glass fiber geogrids are semi-rigid products made from high strength alkali free glass fiber. These raw materials are processed into gridlike base materials by international advanced warp knitting craft. Then the base materials are processed into finished products by surface coating treatment. They have high strength of extension and low elongation in the transverse and longitudinal directions and other excellent properties including high and low temperature resistance, aging resistance and corrosion resistance. They are widely used to protect and control desertification and reinforece railroad beds, dams, revetments, runways and pavements. Geotextiles are geosynthetics with water?permeability made from synthetic fiber by needle punching or weaving. The finished products are generally 4-6m wide and 50-100m long. Geotextiles can be divided into two categories, namely the woven geotextile and non-woven geotextile. Geotextiles perform well in the field of filtration, dewatering, separation, reinforcement and seepage control with properties of good protective effect, light weight, strong strength of extension, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. Geotextiles are geosynthetics. Applications of geosynthetics can date back to the nineteen fifties.
