Geotextiles can be classified into woven (with纺) geotextiles and non-woven (without纺) geotextiles according to the textile method. According to fiber length, they can be divided into filament geotextiles and short fiber geotextiles. In terms of raw materials, there are polyester geotextiles and polypropylene geotextiles. The properties and uses of geotextiles: This product has excellent filtering, drainage, isolation, reinforcement, and protective functions. Geotextiles can be widely used in highways, roads, mobile pavilions, reservoirs, water conservancy projects, tunnels, coastal mudflats, reclamation, environmental protection, power plants, airports, and other projects. By utilizing the good aeration and permeability of geotextiles, water flow can pass through effectively, thus preventing soil erosion. Geotextiles have good drainage capabilities and can form drainage channels within the soil body, discharging necessary solid and gas substances from the soil structure; by enhancing the tensile strength and deformation resistance of the soil body, the stability of the building structure is improved, thereby improving the quality of the soil. Advantages: lightweight, easy excavation, convenient use, shortened construction period, improved economic benefits, and extended service life of the project.
