WHERE TO USE Waterproofing concrete and masonry structures subject to positive or negative hydrostatic pressure. It is recommended for foundation walls, car-parks and underground environments, basins, channels and swimming pools.

Some 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.

TECHNICAL CHARACTERISTICS Mapelastic Foundation is a two-component mortar based on cementitious binders, fine-grained selected inert materials, special additives and synthetic polymers in water dispersion, blended according to a formula developed in MAPEI’s own Research & Development laboratories. 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. Thanks to the high content and quality of the synthetic resins, the 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. Mapelastic Foundation is 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. Mapelastic Foundation also has excellent bonding strength on all cementitious substrates if they have been suitably prepared. All these properties keep structures protected and waterproofed with Mapelastic Foundation perfectly dry over the years.
