1, The good air permeability and water permeability of polypropylene non woven geotextile are utilized to make water flow through, thus effectively intercepting sand loss. 2, Polypropylene non woven geotextile has good water conductivity. It can form drainage channels inside the soil and drain excess liquids and gases out of the soil structure. 3, Polypropylene non woven Geotextile are used to enhance the tensile strength and deformation resistance of soil, to enhance the stability of building structures, and to improve the quality of soil. 3, Effective diffusion, transmission or decomposition of concentrated stress can prevent soil from being damaged by external forces. 4, Prevent the mixing of upper and lower sandstone, soil and concrete. 5, The mesh is not easy to plug, due to the formation of amorphous fibrous tissue network structure has the flexibility and movement. 6, Polypropylene non woven geotextile has high water permeability and can maintain good water permeability under the pressure of soil and water.
