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.
