Geotextile is a new type of building material, made from synthetic fibers of high molecular polymers such as polyester, polypropylene, acrylic, and nylon. According to the manufacturing method, it is divided into two types: woven geotextile and non-woven geotextile. Generally, non-woven geotextile is mainly used in engineering. Geotextile has multiple functions such as impermeability, filtration, drainage, isolation, reinforcement, protection, and sealing. Compared with conventional stone and concrete materials for impermeability, it offers advantages such as lower investment, simpler construction process, shorter construction period, better impermeability effect, and higher effective utilization coefficient of channels. Geotextile can be divided into filament geotextile and short-filament geotextile.

1: Isolation

Using polyester short-fiber needle-punched geotextile to isolate building materials with different physical properties (such as particle size, distribution, consistency, and density), such as soil and sand, soil and concrete. It prevents the loss or mixing of two or more materials, maintains the overall structure and function of the materials, and enhances the load-bearing capacity of the structure.

2: Filtration (Reverse Filtration)

When water flows from a fine soil layer into a coarse soil layer, the good air permeability and water permeability of polyester short-fiber needle-punched geotextile allow water to pass through while effectively intercepting soil particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.

3: Drainage

Polyester short-fiber needle-punched geotextile has good water conductivity. It can form drainage channels inside the soil, discharging excess liquid and gas from the soil structure.

4: Reinforcement

Using polyester short-fiber needle-punched geotextile to enhance the tensile strength and deformation resistance of the soil, improving the stability of the building structure and the quality of the soil.

5: Protection

When water flow scours the soil, it effectively disperses, transmits, or decomposes concentrated stress, preventing the soil from being damaged by external forces and protecting the soil.

6: Puncture Resistance

Combined with geomembrane, it becomes a composite waterproof and impermeable material, serving as puncture resistance.

High tensile strength, good permeability, air permeability, high temperature resistance, freeze resistance, aging resistance, corrosion resistance, and moth resistance.

Polyester short-fiber needle-punched geotextile is a widely used geosynthetic material. It is widely used in the reinforcement of railway roadbeds, maintenance of road surfaces, protection of stadiums and dams, isolation in hydraulic structures, tunnels, coastal mudflats, reclamation, environmental protection, and other engineering projects.
