Geotextiles, also known as geotextile materials, are a new type of construction material, composed of fibers made from high polymer materials such as polyester, polypropylene, acrylic, nylon, etc. They are woven into permeable geosynthetic materials. The products are in fabric form, typically with widths of 4-6 meters and lengths of 50-100 meters. Geotextiles are categorized into woven and non-woven types. They offer filtration, barrier, and protective effects, with high tensile strength, good permeability, heat resistance, frost resistance, aging resistance, and corrosion resistance.

The Effect of Geotextiles: The use of polyester short fiber geotextiles to isolate construction materials with different physical properties (particle size, distribution, density, etc.), such as soil and sand, soil and concrete, etc. This ensures that the materials do not lose their integrity, do not become muddy, and maintain their overall structure and function, thereby enhancing the load-bearing capacity of the structure.

As water flows from fine-grained soil layers into coarse-grained soil layers, the breathable and permeable properties of polyester short fiber geotextile allow the water to pass through while effectively carrying soil particles, fine sand, and small stone materials, thus ensuring the stability of soil and water conservation projects. The polyester short fiber geotextile's water-conducting function creates drainage channels within the soil, expelling excess liquid and gas from the soil structure.

Utilizing polyester short fiber geotextiles to enhance the tensile and deformation resistance of soil, thus improving the stability of construction structures. During the erosion of soil by water flow, these geotextiles effectively concentrate and dissipate stress, transferring or diffusing it to prevent damage to the soil from external forces, thereby protecting the soil.

The composite waterproof and impermeable material, formed by combining geotextile with geomembrane, provides puncture resistance. It boasts high tensile strength, excellent permeability, breathability, heat resistance, frost resistance, aging resistance, corrosion resistance, and is termite-proof. Polyester short fiber geotextile is a type of commonly used geosynthetic material. It is utilized for reinforcing railway subgrades, maintaining road surfaces, sports facilities, dam protection, water engineering barriers, tunnels, coastal beaches, reclamation projects, and more.
