Ⅰ.Product Introduction
The staple fiber needle-punched non-woven geotextiles is produced by using polypropylene or polyester staple fiber as the main raw material, which is opened, combed, messed, laid, and needled.
Ⅱ.Product Characteristics
1. The mesh is not easily blocked, and the network structure formed by the amorphous fibrous structure is flexible and mobile.
2. High water permeability, and maintaining good water permeability even under earthwork pressure.
3. Corrosion-resistant; resistant to acid and alkali, non-corrosive, non-insect, anti-oxidation, being made of polypropylene or polyester fiber raw materials.
4. Simple construction, light weight and easy to use.
3.Product Applications
1. The good air permeability and water permeability of the geotextiles are used to make the water flow through, so as to effectively retain the sand loss.
2. The geotextiles has good water conductivity, and it can form a drainage channel inside the soil mass to discharge excess liquid and gas in the soil structure.
3. The geotextiles is used to enhance the tensile strength and detortion resistance of the soil mass, and to enhance the stability of the building structure so as to improve the soil quality.
4. Effectively spreading, transferring or decomposing the concentrated stress to prevent the soil mass from being damaged by external forces.
5. Preventing mixing among upper and lower sandstone, soil mass and concrete.
