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 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
