Long-fiber geotextile is a new type of construction material specified for civil engineering projects by national regulations. It is woven into a mesh by long fiber filaments through various equipment and processes, and then interlaced and bonded together using techniques like needle-punching, resulting in a standardized fabric that is soft, full, thick, and firm. This allows the fabric to achieve different thicknesses to meet usage requirements. Long-fiber geotextile boasts excellent mechanical properties, good permeability, and resistance to corrosion and aging. It provides functions such as isolation, anti-filtration, drainage, protection, stabilization, and reinforcement, and can adapt to uneven bases, withstand external construction forces, exhibit low creepage, and maintain its original functionality under long-term loads.
I. Product Performance
This production line utilizes advanced technology from the international industry sector, including the first-time application of advanced twin-screw extrusion technology, double-row yarn system, pipeline airflow stretching technology, flat-style yarn placement system, and high-speed needle-punching fabric production process, among 18 international and domestic patented technologies. The product boasts high strength, resistance to aging, acid and alkali resistance, wear resistance, good flexibility, and ease of installation.
1. Free of chemical additives, an environmentally friendly building material

3. Highly resistant to burial and corrosion, with a fluffy structure and excellent drainage properties.
4. Excellent coefficient of friction and tensile strength, with geosynthetic reinforcement properties
5. Features include isolation, anti-filtration, drainage, protection, stabilization, and reinforcement.
6. Adaptable to uneven subgrades, resistant to constructional external forces, and with minimal creep.
7. Good overall continuity, lightweight, and easy to install
8. Designed for permeable materials, it boasts excellent anti-filtering and isolation properties, strong puncture resistance, and thus provides excellent protective performance.
Utilize the good air and water permeability of the long-fiber geotextile to allow water flow through, effectively intercepting soil erosion.
◆ The long-fiber geotextile has excellent water-permeability, which can form drainage channels within the soil mass, expelling excess liquids and gases from the soil structure.
◆ Utilize geotextiles to enhance the tensile strength and deformation resistance of soil, thereby improving the stability of the building structure and the quality of the soil.
◆ Effectively dissipate, transfer, or decompose concentrated stress, preventing soil from being damaged by external forces.
Prevent mixing of aggregates, soil, and concrete between the upper and lower layers.
◆ The mesh is not prone to clogging; the reticular structure formed by the amorphous fiber tissue has elasticity and mobility.
◆ High Water Permeability – Maintains good permeability under soil and water pressure.
◆ Corrosion-resistant - Made from materials like polypropylene or polyester, it is resistant to acids and alkalis, non-corrosive, non-rodent, and anti-oxidation.
◆ Advantages: Lightweight, easy installation, convenient use, shortened construction period, improved economic benefits, and extended service life of the project.
Section II: Product Applications
1. Reinforcement for soil-retaining wall backfill or for anchoring retaining wall panels. Construct encasement-type retaining walls or bridge abutments.
2. Reinforce flexible road surfaces, repair cracks in the roads, and prevent reflective cracking on the pavement.
3. Enhance the stability of crushed rock slopes and reinforced earth, preventing soil erosion and frost damage to the soil mass during cold temperatures.
4. The separation layer between the roadbed and the subgrade, or between the subgrade and the soft foundation.
5. Soil, stone, or material filling, and separation layers between foundations; isolation between different frozen soil layers. Anti-filtering and reinforcement functions.
6. Filter layer in the upstream face of the embankment for ash storage or tailings dam, and in the backfill soil of the retaining wall drainage system.
7. Filter layer around the drainage pipe or around the gravel drainage trench.
8. Filter layers for water wells, pressure-reducing wells, or inclined pressure pipes in hydraulic engineering.
9. Road, airport, railway ballast, and artificial stone embankment separation layers between subgrade and geotextiles
10. Internal vertical or horizontal drainage of earthen dams, embedded in soil to dissipate the pressure of void water.
Drainage behind or beneath the concrete facing in embankments or dams with impermeable geomembranes.
12. Eliminate seepage around the tunnel, reduce the external water pressure on the lining, and mitigate seepage around each building.
13. Drainage for manual-filled land foundation athletic field foundation.
14. Highway (including temporary roads), railway, embankments, earthen dams, airports, sports fields, etc., for reinforcing weak foundations
