Detailed product description
1.geotextile has good air permeability and water permeability, allowing the water to flow through, so as to effectively intercept sandy soil erosion
2.Geotextile has good hydraulic properties, it can be in inside the soil to form a drain channel, soil mass structural excess liquid and gas efflux
3.Use geotextiles to enhance the tensile strength of the soil strength and deformation resistance, enhanced stability of the building structure, to improve the quality of the soil.
4.The concentration diffusion, transfer or decomposition, prevents soil by the action of external force destruction.
5.To prevent the upper and lower sand mix with soil
6.The mesh is not easily blocked, Because the amorphous formation of fibrous tissue in the reticular structure can be changed.
7.High permeability,under water pressure, can still maintain good permeability
8.Corrosion resistance, use polypropylene or polyester, chemical fiber as raw material, acid and alkali resistance, no corrosion,
9,Construction, light weight, convenient use, simple construction
Main uses
Building waterproofing, insulation, roof waterproof coiled material and asphalt tile substrate and other uses.
