Separation and Stabilisation

Separation = 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 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

• Increases 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
