The characteristics and functions of geotextile



1. High strength. Due to the use of plastic fibers, it can maintain sufficient strength and elongation in dry and wet conditions.

2. Corrosion resistance, long-term corrosion resistance in mud and water with different pH.

3. Good water permeability. There are gaps between the fibers, so it has good water permeability.

4. Good anti-microbial properties, no damage to microorganisms and insects.

5. Convenient construction. Because the material is light and soft, it is convenient to transport, lay and construct.


1: Isolation

Use polyester staple fiber needle-punched geotextile for construction materials with different physical properties (particle size, distribution, consistency, density, etc.)

Materials (such as soil and sand, soil and concrete, etc.). Makes two or more materials not lost or mixed, keeping materials

The overall structure and function of the materials strengthen the load-bearing capacity of the structure.

2: Filter (reverse filter)

When water flows from the fine material soil layer into the coarse material soil layer, the good air permeability and water permeability of the polyester staple fiber needle-punched geotextile are used to make the water flow

Pass, and effectively intercept soil particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.

3: Drainage

The polyester staple fiber needle-punched geotextile has good water conductivity. It can form a drainage channel inside the soil body, and make the soil structure more

The remaining liquid and gas are discharged outside.

4: Reinforcement

Use polyester staple fiber needle-punched geotextiles to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve

Good soil quality.

5: Protection

When the water flow scours the soil, it effectively spreads, transmits or decomposes the concentrated stress, prevents the soil from being damaged by external forces, and protects the soil.

6: Anti-puncture

Combined with the geomembrane, it becomes a composite waterproof and impermeable material, which plays a role of preventing puncture.

High tensile strength, good permeability, air permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, and no insects.

Polyester staple fiber needle-punched geotextile is a widely used geosynthetic material. Widely used in the reinforcement of railway subgrades and highway pavements

Maintenance, sports halls, protection of dams, isolation of hydraulic structures, tunnels, coastal beaches, reclamation, and other projects.
