Pre-applied waterproofing membranes that bond integrally to poured concrete for use below slabs or behind basement walls on confined sites.

  • Forms a unique continuous adhesive bond to concrete poured against it- prevents water migration & makes it unaffected by ground settlement beneath slabs
  • Fully-adhered adhesive to adhesive watertight ZipLaps & easy to execute detailing
  • Provides a barrier to water, moisture & gas- physically isolates the structure from the surrounding ground
  • Easy roll/kick out installation- reduces installation time & 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 & ready for immediate placing of reinforcement
  • Unaffected by wet conditions- cannot activate prematurely
  • Inherently waterproof, non-reactive system: 1. Not reliant on confining pressures or hydration2. Unaffected by freeze/thaw, wet/dry cycling
  • Chemical resistant- effective in most types of soils & waters, protects structure from salt or sulphate attack

Preprufe® 300R Plus & 160R Plus membranes are unique composite sheets comprised of a thick HDPE film, pressure sensitive adhesive and weather resistant protective coating. Designed with Advanced Bond Technology™ and a dual adhesive ZipLap™, Preprufe Plus membranes form a unique, integral bond to poured concrete, preventing both the ingress and lateral migration of water while providing a robust barrier to water, moisture and gas. Release liner free and designed for efficient, reliable installation, the Preprufe Plus ZipLap allows for an adhesive to adhesive bond at seam overlaps and delivers superior performance in harsh conditions without the need for specialized equipment, heat or power.
