Geotextile for erosion control

DuPont™ Typar® SF is an ideal filter for erosion control and is used to replace multi-phased aggregate filters because it:

  • Eliminates long term hydrostatic pressure
  • Ensures longer service resistance thanks to its homogeneous and uniform composition
  • Prevents piping and scouring of soils around them

A geotextile replaces a conventional well-graded filter between soil to be retained and gabions, rip-rap or concrete slabs revetments, which protect the filter geotextile.The geotextile's particular opening size retains the soil and so avoids erosion of the slope.

Principally used for :

  • Roads
  • Roofing systems
  • Landscaping
  • Building foundation
  • Footpaths

DuPont™ Typar®

Specifically developed to respond to the installation challenges of geotextile the DuPont™ Typar® products are an important breakthrough compared to other traditional construction techniques.
