The geotextile manufacturer will answer for you when to use Geotextile

(1) It is used as reinforcement in backfill of retaining wall or for anchoring the panel of retaining wall. Construction of wrapped retaining walls or abutments.

(2) Strengthen the flexible pavement, repair the cracks on the road, and prevent the reflection cracks on the road.

(3) Increase the stability of gravel slope and reinforced soil to prevent soil erosion and freeze damage of soil at low temperature

(4) Isolation layer between ballast and subgrade, or between subgrade and soft subgrade.

(5) Isolation layer between artificial fill, rockfill or material field and foundation, and isolation between different frozen soil layers. Anti filtration and reinforcement.

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

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

(8) The filter of a well, relief well, or baroclinic pipe in hydraulic engineering.

(9) Isolation layer of geotextile between road, airport, railway, artificial rockfill and foundation

(10) The vertical or horizontal drainage inside the earth dam is buried in the soil to dissipate the pore water pressure.

(11) Drainage behind impervious geomembrane or under concrete cover in earth dam or embankment.

(12) Remove the water seepage around the tunnel, reduce the external water pressure on the lining and the water seepage around the buildings

(13) Drainage of the foundation of the artificial fill ground playground.

(14) Highway (including temporary road), railway, embankment, earth rock dam, airport, playground and other projects are used to strengthen weak foundation

According to the relevant data, there are three different forms of geotextiles when they play the role of reinforcement: diaphragm type, shear type and anchor type. The hydraulic performance of geotextile is also an important performance of interaction between soil and geotextile, mainly including the effective pore diameter and permeability coefficient of geotextile. Water board and other waterproof materials. Geotextile series are mainly used for:

1. Municipal environmental protection, environmental sanitation and anti-seepage works (such as domestic waste landfill, sewage treatment, toxic and harmful substance treatment yard, dangerous goods warehouse, industrial waste, construction and blasting waste, etc.)

2. Water conservancy anti-seepage works (such as anti-seepage, leakage stoppage, reinforcement of rivers, lakes and reservoirs, anti-seepage of canals, vertical core walls, slope protection, etc.)

3. Anti seepage and waterproof works of municipal works (subway, underground works of buildings and roof reservoir, anti seepage of roof garden, lining of sewage pipes, etc.)

4. Anti seepage works for landscaping waterscape (artificial lake, pond, bottom lining of golf course, slope protection, etc.)

5. Anti seepage and anti-corrosion engineering in metallurgical and petrochemical industry (anti seepage of oil storage tanks in chemical plants, refineries and gas stations, lining of chemical reaction tanks, sedimentation tanks, secondary lining, etc.)

6. Anti seepage and anti-corrosion works in the mining industry (anti-seepage of low lining of washing basin, heap leaching basin, ash yard, dissolution basin, sedimentation basin, storage yard, tailings, etc.)

7. Seepage control works of traffic infrastructure (foundation reinforcement of highway, seepage control of culvert)

8. Agricultural water conservancy seepage control project (seepage control of reservoir, drinking water pool, impoundment pool and irrigation system)

9. Aquaculture industry (fish pond, shrimp pond anti-seepage engineering, etc.).
