What Does Geotextile Do?

Geotextile is a water-permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is in the form of cloth, with a general width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.

Effect

1: Isolation

Polyester staple fiber needle-punched geotextile is used to isolate building materials (such as soil and sand, soil and concrete, etc.) with different physical properties (particle size, distribution, consistency and density, etc.). 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: Filtering (reverse filtering)

When water flows from the fine soil layer into the coarse soil layer, the polyester staple fiber needle-punched geotextile's good air permeability and water permeability are used to allow the water to pass through and effectively intercept soil particles, fine sand, small stones, etc. to maintain Soil and water engineering stability.

3: Drainage

Polyester staple fiber needle-punched geotextile has good water conductivity. It can form drainage channels inside the soil to drain excess liquid and gas out of the soil structure.

4: Reinforcement

Polyester staple fiber needle-punched geotextile is used to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil.

5: Protection

When water flows against the soil, it effectively diffuses, transfers or decomposes the concentrated stress, preventing the soil from being damaged by external forces and protecting the soil.

6: Anti-puncture

Combined with the geomembrane to form a composite waterproof and anti-seepage material, it can prevent 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. It is widely used in railway roadbed reinforcement, highway pavement maintenance, sports halls, dam protection, hydraulic construction isolation, tunnels, coastal beaches, reclamation, environmental protection and other projects.

Features

It is light in weight, low in cost, corrosion-resistant, and has excellent properties such as reverse filtration, drainage, isolation, and reinforcement.

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

2. Corrosion-resistant, can resist corrosion for a long time in soil and water with different pH levels.

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

4. Good anti-microbial properties and will not be damaged by microorganisms or insects.

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

6. Complete specifications: width up to 9 meters. It is the widest product in China, with mass per unit area: 100-1000g/square meter.

Use

Widely used in geotechnical projects such as water conservancy, electric power, mines, roads and railways:

1. Filter material for soil layer separation;

2. Drainage materials for reservoirs and mines, and drainage materials for high-rise building foundations;

3. Anti-scouring materials for river dams and slope protection;

4. Reinforcing materials for railways, highways and airport runways, and reinforcement materials for road construction in swamp areas;

5. Anti-frost and anti-freeze insulation materials;

6. Anti-crack materials for asphalt pavement.

Application areas

(1) Used as reinforcement in retaining wall backfill, or used to anchor retaining wall panels. Build wrapped retaining walls or abutments.

(2) Reinforce flexible pavement, repair cracks on the road, and prevent reflective cracks on the road.

(3) Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage to the soil at low temperatures.

(4) The isolation layer between the road ballast and the roadbed, or the isolation layer between the roadbed and the soft foundation.

(5) The isolation layer between the artificial fill, rock pile or material field and the foundation, and the isolation between different frozen soil layers. Reverse filtration and reinforcement.

(6) The filter layer on the initial upstream dam surface of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill soil of the retaining wall.

(7) The filter layer around the underground drainage pipe or the gravel drainage ditch.

(8) The filter layer of water wells, pressure relief wells or baroclinic pipes in water conservancy projects.

(9) Geotextile isolation layer between highways, airports, railway tunnels, artificial rockfills, etc. and the foundation.

(10) Vertical or horizontal drainage inside the earth dam, embedded in the soil to dissipate pore water pressure.

(11) Drainage behind the anti-seepage geomembrane or under the concrete face in earth dams or embankments.

(12) Eliminate water seepage around the tunnel and reduce external water pressure on the lining and water seepage around the buildings.

(13) Drainage of artificially filled sports ground foundation.

(14) Used to strengthen weak foundations in highways (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields and other projects.
