Geotextile is a water-permeable geomaterial made of synthetic fibers (such as polyester, polypropylene, etc.
Geotextile is a water-permeable geomaterial made of synthetic fibers (such as polyester, polypropylene, etc.) and is mainly used in civil engineering and construction fields. The main functions and applications of geotextiles are as follows:
Function
1. Filtering effect:
- Geotextiles prevent soil particles, fine sand, small rocks, etc. from escaping from the soil while allowing moisture to pass through. Commonly used in filtration structures in rivers, dams and channels to prevent soil erosion.
2. Drainage function:
- Geotextile has good water permeability and can quickly remove excess water from the soil, thereby effectively reducing the water pressure in the soil and preventing damage to the soil structure.
3. Isolation effect:
- Geotextile can effectively isolate soil or materials of different particle sizes and avoid mixing between different materials. For example, in road or railway construction, geotextiles are used to isolate soil layers of different particle sizes to maintain the stability of the foundation.
4. Reinforcing effect:
- Geotextile can enhance the tensile strength of the soil and improve the overall stability of the soil. It is often used to reinforce structures such as steep slopes and retaining walls to increase their tensile strength and stability.
5. Protective effect:
- Geotextiles can protect the soil surface and prevent wind and rain erosion, and are often used in slope protection projects.

Application
1. Road and Railway Construction:
- During the construction of roads and railways, geotextiles are often used to reinforce and stabilize foundations to prevent foundation sinking and road surface cracking.
2. Water conservancy project:
- In water conservancy projects such as dams, rivers, and lakes, geotextiles are used as filter materials to prevent soil loss, as well as for anti-seepage and drainage.
3. Landfill:
- Geotextiles can be used in the anti-seepage and drainage systems of landfills to prevent harmful substances from seeping into groundwater and effectively remove leachate.
4. Building Basic Engineering:
- Geotextiles are used for isolation and drainage of building foundations, protecting the basic structure from moisture and extending the service life of the building.
5. Garden Project:
- In landscaping, geotextiles are often used to prevent weed growth and provide drainage and soil stability.
Geotextiles have become an important material in modern civil engineering due to their versatility and durability.
