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.

FEATURES AND BENEFITS

Advantages
  • 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
