Engineered from continuous polypropylene or polyester filaments, our needle-punched long-filament geotextile delivers exceptional tensile strength, puncture resistance, and hydraulic efficiency. Designed for critical infrastructure projects where reliability and longevity are non-negotiable.
✅ Higher Strength-to-Weight Ratio
30–50% greater tensile strength at equivalent weights
Reduced material usage without compromising performance
✅ Enhanced Hydraulic Consistency
Uniform filament structure ensures stable flow rates (perm: 0.8–3.0 sec⁻¹)
Controlled pore size distribution (O₉₀: 70–200 μm) prevents soil piping
✅ Superior Durability
Continuous filaments resist fiber shedding during installation
Excellent creep resistance under sustained loads
UV-stabilized for 6–12+ months exposure
✅ Critical Project Savings
Thinner installations save excavation/backfill costs
Faster deployment with reduced seam overlaps
