Filament Geotextile

Filament Geotextile, also named "continuous filament nonwoven drainage fabric", is a high-performance geosynthetic material manufactured from continuous synthetic filaments through warp-knitting or thermal-bonding processes.

Our filament geotextile delivers outstanding separation, filtration, reinforcement and protection capabilities, with superior mechanical strength and durability for critical infrastructure applications.

Raw Materials: PET

Packing Method: Bagged Rolls

Characteristics of Filament Geotextile

1. Excellent heat and light resistance：
  
  Even if filament geotextile is exposed to an environment close to 20℃ for a short time, the performance remains almost unchanged.
2. Long-term corrosion resistance：
  
  After a large number of experiments and practical verification, filament geotextile has long-lasting corrosion resistance.
3. Excellent drainage performance：
  
  Filament geotextile demonstrates effective drainage, keeping the soil dry and improving stability.
  
  Comprehensive soil protection：
4. Filament geotextile provides effective protection and reinforcement for various natural soils, moisture and microorganisms.
5. A variety of specifications are available：
  
  The width of filament geotextile is generally 3-6 meters, the length is 5-200 meters, and the weight range is between 100g and 800g to meet different needs. (Support customizable)
