Avoid rutting of roads

DuPont™ Typar® SF products are especially designed to respond to the needs of road applications.

Rutting is a substantial aspect to consider especially for temporary road structures. The regular passage of transport on the structure causes in-plane tensile stresses and activates related membranes and restrains mechanisms. 


Typar® SF is principally used for:

  • Temporary roads, access roads, forest roads
  • Permanent roads, airport runways and taxiways, highways
  • Parking lots, storage yards

DuPont™ Typar® SF products:

  • Are easy to install
  • Lower rutting formation
  • Avoid contamination by subsoil
  • Ensure longer service life (in the case of permanent roads, parking lots and storage yards)

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.
