Our Needle-Punched Nonwoven Long-Fiber Geotextile is a premium geosynthetic fabric engineered for applications demanding exceptional tensile strength, long-term stability, and resistance to mechanical stress. Made from continuous polyester (PET) or polypropylene (PP) filaments bonded through advanced needle-punching technology, this geotextile outperforms traditional short-fiber variants in heavy-duty scenarios such as road construction, embankment reinforcement, and landfill engineering. Its interlocked filament structure ensures uniform load distribution, superior puncture resistance, and extended service life—making it the ultimate choice for infrastructure projects requiring reliability and durability.
High Tensile Strength
Filament Structure: Continuous fibers provide multidirectional strength (15–40 kN/m), ideal for load-bearing applications.
Elongation Control: Low elongation under stress (<50%) maintains structural integrity during ground movement.
Enhanced Durability
Puncture & Tear Resistance: Withstands sharp aggregates, roots, and construction stresses.
UV & Chemical Stability: Resists degradation from sunlight, acids, alkalis, and biological agents (pH 2–13).
Balanced Permeability
Optimal Flow Rate: Hydraulic conductivity of 0.1–1.5 cm/s (ASTM D4491) ensures efficient drainage without soil loss.
Clogging Resistance: Open yet stable structure retains fine particles while allowing water passage.
Cost-Effective Longevity
50+ Year Lifespan: Minimal maintenance required compared to short-fiber geotextiles in high-stress environments.
| Feature | Long-Fiber Geotextile | Short-Fiber Geotextile |
|---|---|---|
| Fiber Structure | Continuous filaments (interlocked) | Staple fibers (randomly oriented) |
| Tensile Strength | Higher (15–40 kN/m) | Lower (5–25 kN/m) |
| Puncture Resistance | Superior (ideal for rocky substrates) | Moderate |
| Permeability | Moderate (balanced drainage) | High (rapid water flow) |
| Applications | Road bases, landfills, slopes >30° | Drainage, erosion control, landscaping |
| Cost Efficiency | Higher upfront cost, lower lifecycle | Lower upfront cost, moderate lifecycle |
