Produced with a firm interlocking bond and exhibit high abrasion resistance.
It is a needle-punched nonwovens which have a high elongation characteristics due to the "flexible", non-brittle fibre junctions created by the manufacturing process.
Application :
- Protection layer in tunnel application.
- Soil separator.
- Off-shore protection (sand container)
- Protection layer in landfill application.
- River bank revetment system.
Advantage :
- Excellent puncture and penetration resistance
- Flexible product
- High interface friction angles
- Long term filter stability
- High water permeability
- High abrasion resistance.
