Mapei Foundation Waterproofing Mortar, Component A, 22Kg, Suitable for Below-Ground Concrete Structures

Mapei Mapelastic Foundation is a polymer-modified cementitious waterproofing mortar designed to waterproof and protect concrete and screed. It helps resist crack propagation, offers high flexibility, and provides durable protection against water ingress on areas prone to cracking.

A 22 kg bag covers up to 16 m2 at a thickness of 1 mm.

No mixing is required. The product is ready-to-use and is applied by adhering it with a suitable adhesive to the prepared substrate.

It is designed for waterproofing and protecting concrete and screed surfaces, including areas with potential cracking, such as balconies, terraces, flat roofs, and insulated substrates.

Key features include waterproofing performance suitable for permanent water exposure, high flexibility to accommodate movement, UV resistance with color retention, and durability for long-term protection.

Ideal applications include balconies, terraces, flat roofs, insulated surfaces, and other areas prone to cracking or water exposure where a durable waterproofing layer is needed.

Prepare a clean, sound substrate. Use a suitable adhesive to bond the Mapelastic Foundation in place, ensuring full contact and embedding. Apply to achieve the recommended thickness (1 mm for the stated coverage) and allow appropriate curing time based on site conditions.
