Water permeable anti-root barrier

DuPont™ Plantex® RootProtector, the most effectively water permeable anti-root barrier. A unique structure of exceptionally thin fibres joined through thermal binding. Perfect for use in horizontal installations, such as construction of cycle tracks, forest lanes or green roofs.


  • The water permeability of the membrane ensures a free flow of water and prevents problems related to hydrostatic pressure as well as low load capacity in high humidity areas
  • The proper water drainage enables a long term maintenance of the ground’s bearing capacity, which ensures high durability of the road construction
  • Tear resistant
  • Guarantees a uniform content of water in the soil, which increases stability of the embankments as well as any other forms
