Fields of application
For the external waterproofing of masonry and concrete below ground level for basement walls, concrete floor slabs, lean concrete (i.e. beneath floor concrete slab), foundations, ceiling slabs of car parking decks in cases of ground damp, non-pressure and pressure water. Also convenient for the intermediate waterproofing of wet-duty rooms, not- inhabited balconies and terraces under floor screed. In addition, for spot-bonding or full- surface bonding of extruded polystyrene rigid-foam boards used as protective, drainage or perimeter insulation boards (depending on the specific use) on the pre-said building parts. For outdoors.
- solvent-free, hence environment-friendly
- flexible and crack-bridging
- high dry residue approx. 85%
- a 1.2 mm thick wet layer provides approx. a 1.0 mm thick dry layer
- quickly resistant to rain after 2.5 - 3 hours at 4 mm layer thickness
- suitable for any mineral substrates; no cement render is necessary on masonry
- resistant to ageing, to water attacking concrete up to the level “highly corrosive” in accordance with DIN 4030 (up to 3.000 mg sulphate per liter of water) and also to seawater
- resistant to frost and thawing salts after full drying
- radon gas-tight
- sprayable with peristaltic pump and screw pump technology, e.g. Wagner PC 1030 with air support
