Nonwoven Geotextile is a textile with irregular pattern which is not woven. Usually Nonwoven Geotextile filments is being put together through chemical, heat and also needle punching methods. Nonwoven Geotextile usually produced using Polypropylene (PP) materials or Polyester (PET).
Nonwoven Geotextile Application
- Road construction
- Soft soil stabilization
- Filtration layer
- Railway construction
- Land reclamation
- Drainage system
- Protection layer for geomembrane
Advantages of Nonwoven Geotextile
- Cost effective
- Good filtration layer
- High UV resistance
- High puncture resistance
- High performance
- Increase soil stability
- Resistance to heat
