It's All in the Detail: E3 Internal Moisture and Mapei Products

Mapei has over 87 years of experience manufacturing and supplying waterproofing products to the international building industry. Mapei products for application in internal wet areas include Mapelastic AquaDefense and Mapegum WPS which are synthetic resin based one-component water dispersion membranes. These types of membranes do not re-emulsify once cured. Mapelastic Smart is a two-component cementitious based membrane that has full tanking capabilities and is the recommended membrane for installation over composite timber substrates, including acoustic underlayment. 

The key to a watertight and long service waterproofing installation is all in the detail. This is why Mapei manufacture and supply waterproof tapes as part of the waterproofing system. These waterproofing tapes are essential system components used in the critical stress areas of the waterproofing installation, such as the wall/floor junctions, expansion joints, and any other change in plane. Mapeband SA is a butyl-based peel and stick tape has an elongation at breaking point of over 480%, while Mapeband Easy is a rubber-based tape with an elongation at breaking point of over 300%. As you can see these waterproof tapes are capable of being put under an enormous amount or stress that will exceed any normal building substrate movement.

With the recent addition of AS/1 AS/2 Alternative Solution to E3 Internal Moisture, Mapei has developed waterproofing systems for other top cover flooring categories such as LVT, hybrid, Laminate and Engineered Timber Flooring.

Mapei also has also developed systems for a second line of defence for waterproofing under sheet vinyl in wet areas that are installed in high use hospital and aged care wet room applications.

Mapei waterproofing systems are backed up with BRANZ Appraisals and can be specified in Masterspec, Smart Spec and through contacting a local Mapei representative for a project specific specification. Mapei can also provide documentation for Living Building Challenge and Green Star projects through our LEED V4.1 Certification.
