Our nonwoven staple fiber geotextile delivers unmatched performance in soil separation, filtration, and subsurface drainage. Manufactured from high-tenacity polypropylene or polyester fibers through advanced needle-punching technology, it provides superior puncture resistance, elongation, and hydraulic properties for demanding civil and environmental projects.

Key Benefits & Features

✅ Exceptional Filtration Efficiency

• Optimal pore size distribution (O90: [e.g., 100–300 μm]) retains soil particles while allowing free water passage

• Prevents soil migration in drainage systems, retaining walls, and erosion control applications

✅ Robust Physical Durability

• High puncture resistance ([e.g., ≥ 800 N] per ASTM D4833) withstands installation stresses

• Excellent elongation (50–80%) conforms to irregular subgrades

• UV-stabilized for extended exposure (≥ [e.g., 6 months] retention strength)

✅ Superior Hydraulic Performance

• Permittivity: [e.g., 0.5–2.0 sec⁻¹] (ASTM D4491)

• High flow rates for drainage layers beneath roads, ponds, and landfills

✅ Cost-Effective Soil Separation

• Prevents intermixing of soil layers under roads, railways, and embankments

• Reduces aggregate thickness by up to 30%

✅ Environmentally Resilient

• Resists rot, chemicals, and biological degradation

• Operating temperature: -60°C to +100°C
