Needle Punched Non Woven Geotextile Fabric Specification
Features of Geotextile
1 Superior water permeability
2 Filtrability
3 Deformation adaptive faculty
4 Resistant to corrosion
5 Anti-aging
- Geotextile has high water diversion property, it can form drainage passageway, transpire the surplus liquid and gas
- High water permeability even under the pressure of soil and water
- Spread, transfer or decompose the concentrate stress effectively to avoid the soil be damaged by outside affection
- To prevent the freestone upper and lower level, soil and concrete mixed
- Polypropylene fiber or polyester fiber and other chemical fiber as raw material, acid-alkali-proof, corrosion resisting, non warm-eaten,antioxidant
- Light, convenient to use, easy construction, shorten working-period, increase economic efficiency
- Make use of geotextile to strengthen the tensile strength and anti-deformation property of soil, increase the stability of building structure, and also improve the soil quality
