Geotextile is a new type of construction material used in civil engineering. The main material is polyester fiber, which is laid into a mesh by using different equipment and processes such as filament or staple fibers. After being needled, different fibers are interwoven with each other, intertwined and fixed to standardize the fabric, making the fabric soft, plump, thick, and stiff, to achieve different thicknesses to meet the use requirements, According to the length of the filament used, it can be divided into filament nonwoven geotextiles or short filament nonwoven geotextiles. The tensile strength of the filament is higher than that of the short filament. Due to the softness of the fiber, it has a certain tear resistance and has good filtration, water filtration, and reinforcement effects.

- Excellent isolation effect: Utilize good air permeability and water permeability of geotechnical cloth, so that the flow of water through, and effectively retain the sand and soil.
- Good water guide and drainage: The geotechnical cloth has good water conductivity, it can form a drainage channel in the soil, and discharge excess liquid and gas out of the soil structure.
- Best creep resistance: By using the geotextile to enhance the soil's tensile strength and anti deformation ability, enhance the stability of the building structure, play the role of reinforcement so as to improve the quality of the soil.
- Protect soil body: Effectively make the concentrated stress diffusion, transmit or decomposition, prevent the soil from being destroyed by external forces.
- Good isolation effect: Prevent the upper and lower layers of gravel, soil and concrete mixed.
- The mesh is not easy to be blocked: Due to unshaped fibrous tissue forms mesh structure has the characteristics of flexibility and Athletic performance.
- High permeability: Under the pressure of the soil and water, it still can maintain good water permeability.
- Corrosion resistance: Polypropylene or polyester fiber as raw material, acid and alkali resistance, no corrosion, no worm damage, antioxidant.
- Convenient construction: Lightweight, easy to use, construction is simple.
