Mapelastic Foundation is a two-component mortar based on cementitious binders, fine-grained selected inert materials,
inorganic fibres, 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.
Mapelastic Foundation fulfils all the main criteria for the EN 1504-9 Standards (“Products and systems for the protection
and repair of concrete structures: definitions, requirements, quality control and conformity assessment. General
principles for the use of products and systems”) and the requirements for EN 1504-2 Standards according to PI-MC-IR
principles (“Protection systems for concrete surfaces”).
Product certified EC1 Plus by the GEV Institute (Gemeinschaft Emissions-kontrollierte Verlegewerkstoffe, e.V.) as a product
with very low emission of volatile organic compounds.
