Product Details
Our Polyester Filament Nonwoven Geotextile is an environmentally friendly construction material made through needle-punching process without chemical additives or heat treatment. This innovative solution replaces traditional engineering materials with safer installation and better environmental protection, offering more economical, efficient and durable answers to engineering challenges.
Key Features & Benefits
✔ Excellent Mechanical Properties - Superior tensile strength in all directions compared to other needle-punched nonwovens of same weight
✔ Outstanding UV Resistance - Exceptional ability to withstand sunlight exposure
✔ High Temperature Tolerance - Maintains structural integrity at temperatures up to 230°C
✔ Superior Permeability - Excellent planar drainage and vertical water permeability that lasts for years
✔ Remarkable Creep Resistance - Better long-term performance than other geotextiles
✔ Chemical Resistance - Withstands common soil chemicals, gasoline, and diesel
✔ Great Elongation - Adapts well to irregular surfaces with proper stress distribution

Primary Functions
1. Separation
Prevents intermixing of different materials (soil/aggregate, soil/concrete) while maintaining structural integrity and improving load-bearing capacity.
2. Filtration (Reverse Filtration)
Allows water flow while effectively retaining soil particles, sand and small aggregates to maintain engineering stability.
3. Drainage
Creates drainage channels within soil structures to remove excess liquids and gases.
4. Reinforcement
Enhances soil tensile strength and deformation resistance, improving structural stability.
5. Protection
Dissipates concentrated stresses from water erosion to prevent soil damage.
6. Puncture Protection
When combined with geomembranes, forms composite waterproofing systems with excellent puncture resistance.
