Needle-punched nonwoven geotextile

Phone:18053450611
The primary function of geotextiles:

Stabilizes and restricts the displacement of civil engineering structures over extended periods, and transmits or distributes the stress applied to the soil over a larger area, thereby increasing the frictional resistance between the soil mass and geotextile.

2. Separate different soil compositions using geotextiles to create a stable separation interface, allowing each layer to be individually isolated and to perform its respective characteristics and overall function as required.

3. Geotextiles can provide protection and erosion control for soil or water surfaces.

4. Geotextiles allow water to pass through while effectively preventing soil particles from passing, thereby avoiding soil particle loss and preventing the destruction of the soil mass.

5. Geotextiles can form drainage channels within soil, collecting moisture from the soil and expelling it along the plane of the material.

6. Geomembranes and composite geomaterials prevent liquid leakage and gas volatilization, ensuring safety for the environment or structures.
