Functions
1: Isolation
Using polyester short fiber needle-punched geotextiles to isolate construction materials with different physical properties (such as particle size, distribution, consistency, and density) (e.g., soil and sand, soil and concrete). This prevents the loss and mixing of two or more materials, maintaining the overall structure and function of the materials, thereby enhancing the load-bearing capacity of the structure.
2: Filtration (Reverse Filtration)
When water flows from fine soil layers into coarse soil layers, the good air permeability and water permeability of polyester short fiber needle-punched geotextiles allow water to flow through while effectively carrying soil particles, fine sand, small stones, etc., to maintain the stability of water and soil engineering.
3: Drainage
Polyester short fiber needle-punched geotextiles have good drainage properties, forming drainage channels within the soil structure to expel excess liquids and gases from the soil structure.
4: Reinforcement
Using polyester short fiber needle-punched geotextiles to enhance the tensile strength and deformation resistance of the soil, improving the stability of the construction structure and the quality of the soil.
5: Protection
When water flows erodes the soil, it effectively diffuses, transmits, or decomposes concentrated stress, preventing damage to the soil from external forces, thus protecting the soil.
6: Puncture Resistance
Combined with geomembranes to form composite waterproof and anti-seepage materials, providing puncture resistance.
High tensile strength, good permeability, breathable, high-temperature resistance, freeze resistance, aging resistance, corrosion resistance, and pest resistance.
Polyester short fiber needle-punched geotextiles are widely used geosynthetic materials. They are extensively used in railway subgrade reinforcement, highway pavement maintenance, sports venues, dam protection, isolation in hydraulic structures, drainage tunnels, coastal reclamation, environmental protection, and other projects.
