Grace Preprufe

The PREPRUFE^® Plus system safeguards foundations against water and moisture infiltration, corrosive and contaminated soil, as well as hazardous gases. With this highly durable membrane, you can:

• Gain protection for the life of the structure
• Speed project completion
• Improve job site safety

Product Advantages

• The unique continuous adhesive bond to concrete poured against it is designed to prevent water migration and make it unaffected by ground settlement beneath slabs.
• Designed with fully adhered adhesive to adhesive watertight ZIPLAP™ seams and easy to execute detailing.
• Designed to provide a barrier to water, moisture and gas and to physically isolate the structure from the surrounding substrate.
• Easy roll/kick out installation reduces installation time and cost.
• Release liner free design expedites installation and reduces construction site waste. Solar reflective surface results in reduced temperature gain.
• Simple and quick to install requiring no priming or fillets.
• Designed to be easily applied to permanent formwork – allows maximum use of confined sites.
• Can be traficked immediately after application and is ready for immediate placing of reinforcement.
• Installed membrane is unaffected by wet jobsite conditions – cannot activate prematurely.
• Inherently waterproof as supplied. Passive non-reactive waterproofing system does not require water activation.
• Waterproofing is not reliant on confining pressures or hydration. Membrane unaffected by freeze/thaw, wet/dry cycling.
• Chemical resistance – designed to protect structures from salt or sulphate attack and is effective in most types of soils and waters. Resistant to methane and radon gasses. Specific independent laboratory test data available on request.
  • Independent Assessments and International Certifications
  • Methane, carbon dioxide and radon gas protection in excess of the standard Membrane requirements in BRE Reports 211 (Radon) and 212 (Methane and Carbon Dioxide)
  • BBA Certificate No. 97/3325.
  • Mott MacDonald Special Services Report May 2001.
