Long-Filament Nonwoven Geotextile High-Strength Separation • Superior Filtration • Engineered Durability

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.

Key Advantages Over Staple Fiber Geotextiles

✅ 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
