The role of the geotextile

  • Author:sany

1: Use of polyester staple fiber nonwoven fabric with different physical properties (particle size, distribution, consistency and density, etc.) of the building materials (such as soil and sand, soil and concrete, etc.) in isolation.To keep the structure and function of the materials in the structure and function of the materials, so as to enhance the capacity of the construction materials. 



2: filtering (anti-filtration)
When water flows into coarse material composed of fine soil soil layer, the use of polyester staple fiber geotextile acupuncture good air permeability and water permeability, make the water flow through, and effectively current-carrying soil particles, sand, small stones, etc., to maintain the stability of soil and water conservation project. 

3: drainage
The dacron short fiber needlework cloth has good guiding water performance, which can form the drainage channel inside the soil, and the extra liquid and gas outside the soil structure. 

4: reinforced
The tensile strength and anti-deformation ability of the soil are strengthened by using the polyester staple fibre needling, so as to improve the stability of the building structure to improve the soil quality. 

5: protective
When the water is scoured by the soil, it will effectively disperse the concentrated stress, transfer or decompose it, and prevent the soil from being destroyed by external forces.
High tensile strength, good permeability, air permeability, high temperature resistance, anti-freezing, aging resistance, corrosion resistance, non-wormproof.
Dacron staple acupuncture is a kind of widely used geosynthetic material.It is widely used in railway embankment and road surface.


The maintenance, sports hall, the protection of the dyke, the isolation of hydraulic construction, the tunnel, the coastal beach, reclamation, environmental protection and other works.
