Filtration - DuPont™ Typar®

Filtration = Rrestraining of soil or other particles subjected to hydrodynamic forces while allowing the passage of fluids into or across a geosynthetic.

DuPont™ Typar® SF provides long term filtration conditions

DuPont™ Typar® SF allows to build up a natural soil filter that provides long-term filtration conditions (reducing blocking / blinding ). It also:

  • Prevents clogging of drainage system
  • Guarantees permeability, thanks to its precompressed structure and its very high number of pores of different shape, size
  • Is predicted to be durable for a minimum of 100 years in all natural soils
  • Is high damage resistant thanks to its high energy absorption potential
  • Lowers material cost since cheaper, coarser filtration aggregates can be used
  • Allows faster and cheaper installation
