Geotextile

Characteristics:Light weight, low cost, corrosion resistance, anti-filtration, drainage, isolation, reinforcement and other excellent properties.

Geotextile, also known as geotextile, it is a permeable geosynthetic material made of synthetic fibers by needling or weaving. Geotextile is one of the new material geosynthetics, the finished product is in the form of cloth, generally 4-6 meters in width and 50-100 meters in length. Geotextile is divided into spun geotextile and non-woven filament geotextile.

Usage
Widely used in water conservancy, electric power, mining, highway and railroad and other geotechnical engineering:
1、Filter material for soil separation;
2、Drainage materials for reservoirs, mine ore dressing, and drainage materials for foundations of high-rise buildings;
3, anti-scouring materials for river dams and berms;
4, railroad, highway, airport runway roadbed reinforcement materials, swampy areas to repair the road reinforcement materials;
5, frost and frost insulation materials;
6、Anti-cracking material for asphalt pavement.
Application fields
(1) Reinforcement in the backfill of retaining wall, or used for anchoring the panel of retaining wall. Constructing wrapped retaining wall or bridge abutment.
(2) Reinforcement of flexible pavements, repair of cracks in roads, and prevention of reflective cracks in pavements.
(3) Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and frost damage to soil at low temperatures.
(4) Isolation layer between road ballast and roadbed, or isolation layer between roadbed and soft base.
(5) Isolation layer between artificial fill, rock pile or material field and foundation, isolation between different frozen soil layers. Anti-filtration and reinforcement.
(6) Filter layer on the initial upstream face of an ash storage dam or tailings dam, filter layer in the drainage system in the backfill of a retaining wall.
(7) Filter layer around drainage culverts or gravel drainage culverts.
(8) Filter layer of water wells, decompression wells or inclined pressure pipes in water conservancy projects.
(9) Separation layer of geotextile between highways, airports, railroads, and artificial rock piles and foundations.
(10) Vertical or horizontal drainage inside an earth dam, buried in the soil to dissipate void water pressure.
(11) Drainage behind the impermeable geomembrane in the earth dam or earth embankment or in the lower part of the concrete sheathing.
(12) Excluding seepage water around the tunnel, reducing the external water pressure on the lining and seepage water around each building.
(13) Drainage of the foundation of sports ground on artificially filled land.
(14) It is used to strengthen the weak foundation in the project of highway (including temporary road), railroad, embankment, earth and stone dam, airport, sports ground and so on.
