Waterproofing concrete and masonry structures subject to positive or negative hydro-static pressure. It is recommended for foundation walls, car-parks and underground environments, basins, channels and swimming pools Application examples: Waterproofing concrete retaining walls Waterproofing underground car-parks, cellars, sunken swimming pools and basins and lift pits against the counter-pressure of water Waterproofing breeze-block walls pre-treated with a suitable MAPEI mortar ADVANTAGES: A two-component mortar based on cementitious binders, fine-grained selected inert materials, special additives and synthetic polymers in water dispersion When the two components are mixed together, a plastic consistency is obtained It may be applied with a roller or by spray on both horizontal and vertical surfaces, at a thickness of at least 2 mm High content and quality of the synthetic resins Hardened layer of Mapelastic Foundation is highly flexible and remains stable under all environmental conditions When mixed, the product is highly thixotropic, which reduces waste to a minimum during the application phase with a roller Completely waterproof against positive pressure, and is waterproof against negative pressure of up to 1.5 atm (15 m column of water). Once cured, it is resistant to soluble salts which are present in sea water or in the ground, such as chlorides and sulphates Excellent bonding strength on all cementitious substrates if they have been suitably prepared
