Separation & Stabilisation

The preventing from intermixing of adjacent dissimilar soils and/or fill materials by the use of geosynthetics. As defined by European standards, the separation function is always used in conjunction with another function.

DuPont™ Typar® SF Products: the leading solution

DuPont™ Typar® SF is an isotropic material, meaning that its physical properties are present in all directions. This mirrors the stresses and strains of a typical separation application.

DuPont™ Typar® SF

  • Improves the load bearing capacity by separating fine-grained subgrade from the aggregate base Increase of the bearing capacity by preventing the loss of aggregate into soft subgrade
  • Increases the compaction degree
  • Reduces the deterioration of roads through frost heave effects
  • Eradicates the need to remove weak subgrade
  • Maintains the drainage capacity of the aggregate base
  • Prevents migration of fine particles
  • Reduces deformations (rutting)
  • Ensures longer lifetime of construction
