Waterproofing with MAPEI’s Mapelastic

May 22, 2020

A product that has always been innovative and ideal for all waterproofing applications from large sites to smaller restorations.

Mapelastic is a two-component, flexible cementitious waterproofer for protection against water ingress on terraces, balconies, bathrooms, bridges, viaducts, dams, underground structures, storage tanks, basins, swimming pools and external coatings. Thanks to its high synthetic resin content, Mapelastic guarantees protection that maintains its flexibility and impermeability to water.

When the two components of Mapelastic are mixed together, they form a flexible mix which is easy to apply in layers up to 2mm thick, including on vertical surfaces. Mapelastic may be applied on both new screeds and existing flooring without removing old tiles.

Mapelastic also forms a barrier against the engress of aggressive agents and has the capacity to protect concrete structures from the aggressive action of carbon dioxide and sodium chloride which are criticalm in the formation of carbonation and chlorides attackes; and calcium chlorides which makes it ideal for use in coastal areas. It is also resistant to UV rays and maintains its flexibility at very low temperatures (-20degC).

New wall and floor coverings may be overlaid directly on the waterproofing membrane, which means that both the structure and the screed are protected and, over the years, efflorescence cannot form between the flooring and subfloor system.

Mapelastic is one of the many waterproofing solutions that Mapei South Africa offers. MAPEI has developed a comprehensive range of different waterproofing systems to cover most of the requirements which are commonly found on local construction projects, combined with the knowledge and international expertise to specify the correct solution needed.
