Preprufe 300R ja 160R

Pre-applied waterproofing membranes for slab foundations and sub-constructions water barrier

Advantages

• Bond completely to poured concrete; that is why water ingress tracking between a membrane and concrete is avoided and soils flash does not effect membrane.
• Forms a barrier against water, moisture and gas between stucture and the surrounding ground.
• BBA sertified for hydroinsulation in basements of grades 2, 3 and 4 according to British Standard BS 8192:1990.
• Solar reflective – reduces temperature forces.
• Simple and quick to install, no primers or fillets required.
• Complete adhesive bond to finishers and units.
• Can be applied to permanent formwork, allows to build under restricted conditions.
• Protection is not required – a membrane can be trafficked immediately after application.
• Falls do not activate adhesive bond prematurely.
• Waterproof system: non-reliant to hydro pressure.
• Unaffected by freeze/thaw and wet/dry cycling.
• Chemical resistant in all types of soils and waters – protects structure against salt or sulphate attacks.
• For ensuring water stops both in movement and working joints, a range of Grace product include active and passive joint strips.

• Preprufe® 300R for use below large weight load foundation slabs. Allows heavy reinforcement.
• Preprufe® 160R is the thinner grade membrane for applications at places with minor load capacity or in case of permanent formwork.
• Preprufe® LT tape for cut edges, roll ends, penetrations and detailing (in temperatures from -40 °C to +300 °C)
• Preprufe® HC tape is similar to the previous one, for use in hot climate (over +100 °C)
• Bituthene® LM liquid membrane is used for sealing around penetrations, etc
