1. Isolation: Geotextile is used to isolate construction materials (such as soil and sand, sand and gravel, soil and concrete, etc.) with different physical properties (particle size, distribution, consistency, density, etc.). Maintain the overall structure and function of the material and enhance the bearing capacity of the structure.

2. Filtration: When water flows from the fine-grained soil layer to the coarse-grained soil layer, use needle-punched polyester nonwoven geotextile for sale to allow water to pass through with good air permeability and water permeability. And effectively intercept soil particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.

3. Drainage: wholesale polypropylene nonwoven geotextile is a good water-conducting material that can form drainage channels in the soil structure to remove excess liquid and gas from the soil structure.

4. Reinforcement: 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: Effectively disperse, transfer or decompose concentrated stress to prevent the soil from being damaged by external force.

6. Sealing: filament nonwoven geotextile manufacturers should be combined with other materials (asphalt, plastic film) to form an impervious barrier layer in the soil layer. (Mainly used for pavement, repair, etc.)
