Geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers by needling or weaving. Geotextile is one of the new geosynthetic materials. The finished product looks like cloth, generally 4-6 meters wide and 50-100 meters long.

Features:

Geotextiles have excellent filtering, drainage, isolation, reinforcement, and protection functions. They have the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freeze resistance, aging resistance, and corrosion resistance. It has been widely used in many fields.

Classification:

There geotextiles mainly divided into woven geotextiles, needle-punched geotextiles, composite geotextiles, other geotextiles, etc.

Characteristics:

1: Isolation

Polyester staple fiber needle punched geotextile is used to isolate construction materials (such as soil and sand, soil and concrete, etc.) with different physical properties (particle size, distribution, consistency, density, etc.). Prevent two or more materials from being lost and mixed, maintain the overall structure and function of the materials, and strengthen the carrying capacity of the structure.
2: Filtration (reverse filtration)

When the water flows from the fine soil layer into the coarse soil layer, the good air permeability and water permeability of the polyester staple fiber needle punched geotextile are used to pass the water flow and effectively intercept the soil particles, fine sand, small stones, etc. to maintain Soil and water engineering stability.
3: Drainage

Polyester staple fiber needle-punched geotextiles have good water conductivity. It can form drainage channels inside the soil and discharge excess liquid and gas in the soil structure.
4: Reinforcement

The polyester staple fiber needle punched geotextile is used to enhance the tensile strength and anti-deformation ability of the soil body, enhance the stability of the building structure, and improve the soil quality.
5: Protection

When water flow scours the soil, it effectively diffuses, transfers or decomposes the concentrated stress, prevents the soil from being damaged by external forces, and protects the soil.
6: Puncture prevention

Combined with geomembrane to form a composite waterproof and anti-seepage material, which plays the role of puncture prevention. High tensile strength, good permeability, breath ability, high temperature resistance, freeze resistance, aging resistance, corrosion resistance, and no moth. Polyester staple fiber geotextile is a widely used geosynthetic material. Widely used in the reinforcement of railway subgrade, maintenance of highway pavement, protection of sports halls, dams, isolation of hydraulic structures, tunnels, beaches, reclamation, environmental protection and other projects.

Usage

Widely used in geotechnical engineering such as water conservancy, electricity, mines, roads and railways:
1. Filter material for soil separation;
2. Drainage materials for the beneficiation of reservoirs and mines, drainage materials for the foundations of high-rise buildings;
3. Anti-scouring materials for river dykes and slope protection;
4. Reinforcing materials for railways, highways, and airport running road foundations, and road-reinforcing materials for swamps
5. Anti-frost and anti-freeze insulation materials;

In infrastructure projects, uneven soil settlement, erosion, and water permeation often pose potential threats to structural stability. Our geosynthetic materials provide effective solutions to these challenges.
Geomembranes can effectively block liquid permeation and are widely used in waterproofing applications such as reservoirs, canals, and landfill liners.
Geotextiles, with their filtration and separation functions, protect soil layers and ensure the stability of road bases and foundations.
Geogrids enhance soil load-bearing capacity and provide crucial support for roads, slopes, and bridges. and other structures.
We offer a comprehensive one-stop geotechnical solution, including professional support throughout material selection, design, and construction. This empowers our clients to address complex geotechnical challenges and ensures the long-term stability and efficient operation of their projects.
