Geotextile fiber:

  • Geotextile is a kind of penetrable polymer material with woven, nonwoven, or knitted structure, used in Geo-technic or civil engineering, and often made of polypropylene fibers which have specific gravity less than one unit and are sturdy and durable. Polypropylene in form of staple fibers and continuous filaments, is used to make woven and non-woven Geotextiles.

 

Advantages:

  • High tensile strength
  • Light weight
  • Flexibility
  • Simple installation and easy transportation
  • Highly durable insulation
  • Low cost and long lifetime

 

Applications:

  • Separating layer of the road
  • Road pavement
  • Railway’s substructure
  • Dams
  • Geo membrane
  • Erosion controlling
  • Protective walls
  • Protective and drainage systems for artificial grass
  • Retrofitting the earth against earthquake
  • Filter in irrigation channels
  • Filter in embankment dams
