Preprufe® 300R & 160R Plus

Preprufe® 300R & 160R Plus membranes are unique composite sheets comprising, a thick HDPE film, an aggressive pressure sensitive adhesive a weather resistant protective coating and an adhesive to adhesive seam overlap.

Unlike conventional non-adhering membranes, which are vulnerable to water ingress tracking between the unbonded membrane and structure, the unique Preprufe bond to concrete prevents ingress or migration of water around the structure.


  • Forms a unique continuous adhesive bond to concrete poured against it — prevents water migration and makes it unaffected by ground settlement beneath slabs
  • Fully-adhered adhesive to adhesive watertight laps and detailing
  • Provides a barrier to water, moisture and gas — physically isolates the structure from the surrounding ground
  • Easy roll/kick out installation — reduces installation time and cost
  • Release Liner free — expedites installation and reduces construction site waste
  • Solar reflective — reduced temperature gain
  • Simple and quick to install — requiring no priming or fillets
  • Can be applied to permanent formwork — allows maximum use of confined sites
  • Self protecting — can be trafficked immediately after application and ready for immediate placing of reinforcement
  • Unaffected by wet conditions — cannot activate prematurely
  • Inherently waterproof, non-reactive system:
    • not reliant on confining pressures or hydration
    • unaffected by freeze/thaw, wet/dry cycling
  • Chemical resistant — effective in most types of soils and waters, protects structure from salt or sulphate attack
