Function and function of filament geotextile:

1. Isolation: refers to the use of long filament geotextiles to isolate building materials with different physical properties (particle size, distribution, consistency, density, etc.), such as soil and sand particles, sand and gravel, soil and concrete, etc. Ensure that two or more materials are not lost or mixed, maintain the overall structure and function of the materials, and enhance the load-bearing capacity of the structure.

2. Filtering: When water flows from fine-grained soil layers into coarse-grained soil layers, the good breathability and water permeability of needle punched long filament geotextiles are utilized to allow water flow through. And it effectively intercepts soil particles, fine sand, small stones, etc. to maintain the stability of soil and water engineering.

3. Drainage: Long filament geotextile is a good water conducting material, and it can form drainage channels in the soil structure to remove excess liquid and gas inside the soil structure.
