Geotextile, also known as geotextile, is a permeable geotextile composed of constituent fibers that are needled or woven. The product is in the form of cloth, with a general width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextiles have excellent filtration, drainage, barrier, reinforcement, seepage prevention and protection effects, and have light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance.

The effect of geotextile filtration When water flows from the fine soil layer to the coarse soil layer, the good permeability and water permeability of the needle-punched geotextile shall be used to make the water flow through and effectively intercept the soil particles, fine yarn, small stone, etc., so as to maintain the stability of the water and soil engineering. The effect of geotextile drainage geotextile is a good water-conducting material, which can form a drainage channel inside the soil body, and remove the remaining liquid and gas from the soil body structure. The effect of geotextile reinforcement uses needle geotextile to enhance the tensile strength and anti-deformation ability of the soil mass, add the stability of the building structure, and improve the soil mass quality. The effect protection of geotextile can effectively disperse, transmit or differentiate the concentrated stress, and prevent the soil from being damaged by external force.
