Description

Product Details

Staple fiber needle-punched geotextile is made of polyester or polypropylene staple fiber through carding or wire needle consolidation.

The product has superior water permeability, filtration, durability, and can be widely used in railways, highways, sports halls, dams, hydraulic buildings, suidong, coastal beaches, reclamation, environmental protection and other projects.

Function:

◎ The use of geotextile good air permeability and water permeability, so that the water flow through, so as to effectively intercept the sand loss.

◎ Geotextile has good water conductivity, it can form a drainage channel inside the soil, the soil structure of excess liquid and gas discharge.

◎ The use of geotextile to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, in order to improve the quality of the soil.

◎ Effective will focus on stress diffusion, transmission or decomposition, to prevent the soil from being damaged by external forces.

◎ Prevent mixing between upper and lower layers of sand and gravel, soil and concrete.

◎ The mesh is not easy to plug-due to the formation of amorphous fibrous tissue network structure should be denatured and dynamic.

◎High water permeability-under the pressure of soil water, it can still maintain good water permeability.

◎ Corrosion resistance-with polypropylene or polyester and other chemical fiber as raw materials, acid and alkali resistance, no corrosion, no moth-eaten, anti-oxidation.

◎ Simple construction-light weight, easy to use, simple construction.
