They are easy to use. It is hard to block the apertures of geotextiles because the net?structure of geotextiles has excellent adaptability and movability. So geotextiles have good water permeability. They can form drainage channels inside the soil mass. Impervious geotextiles have excellent water permeability, filterability and durability. They are widely used to construct railways, highways, stadiums, dams, water conservancy facilities, tunnels, coastal mud flats and for environmental protection.
Geotextiles can be divided into two categories, namely the staple fiber acupuncture non-woven geotextile and film yarn woven geotextile. Geotextiles have excellent breathability, water?permeability, acid resistance, alkali resistance, worm resistance and oxidation resistance.
Geotextiles can improve the strength of extension and deformation resistance, efficiently disperse, transfer or resolve the concentrated stress to protect the soil mass from damage of external force. So they can improve the stability of the buildings and the quality of soil mass.
Geotextiles can be divided into three categories according to craft, namely the filament geotextile, woven geotextile and singeing geotextile.
