The function of polyester filament geotextile

HOME    The function of polyester filament geotextile


1, Seperation That is, the use of geotextiles to seperate building materials (such as soil and sand, sand and gravel, soil and concrete) with different physical properties (particle size, distribution, consistency and density). The two or more materials are not lost or mixed, and the overall structure and function of the material are maintained to enhance the load bearing capacity of the structure.

2, filtration When water flows from the fine-grained soil layer into the coarse-grained soil layer, the water flow is passed through the good gas permeability and water permeability of the needle-punched geotextile. And effectively intercept soil particles, fine sand, small stones, etc., in order to maintain the stability of water and soil engineering.

3. Drainage Geotextile is a good water-conducting material, which can form a drainage channel in the soil structure to remove excess liquid and gas inside the soil structure.

4, Reinforcement The geotextile is used to enhance the tensile strength and deformation resistance of the soil, and to enhance the stability of the building structure to improve the soil quality.


6. Waterproof
