Top-to-the-line Mapelastic AquaDefense joins Mapei’s Waterproofing arsenal

Mapei’s MapelasticTM family of waterproofing and crack-isolation membranes has a reputation for accommodating a wide range of installer preferences, from residential to industrial applications.  As a proud innovator of ecologically sustainable solutions, Mapei produces waterproofing membranes that are all KEED compliant, which helps contribute valuable points toward today’s growing number of LEED-Certified projects.

The latest addition to the Mapelastic family is new Mapelastic AquaDefense.  This premixed, ready-to-use, flexible, thin, liquid-applied, fast drying waterproofing and crack-isolation membrane has been designed to take on the construction industry’s most challenging applications.

What sets Mapelastic AquaDefense apart?

Renowned for its commitment to technologically advanced products and systems that are faster, easier and smarter, Mapei now offers Mapelastic AquaDefense premium waterproofing and crack-isolation membrane.  This product is Mapei’s fastest drying, easiest waterproofing membrane solution for interior / exterior uses including residential, commercial and industrial (interior only) applications.

Mapelastic AquaDefense performs double duty by first providing a continuous barrier that protects adjacent rooms or floors below from potential water migration through grout joints or porous stone.  Secondly, industrial-strength Mapelastic AquaDefense prevents in-plane cracks upto 1/8” (3mm) thick from transmitting through tile or stone.

This user-friendly, ultra-versatile membrane is easily applied to flat, curved and irregular floors, walls and ceilings with a roller or brush.  Mapelastic AquaDefense offers tenacious bond to the variety of substrates including fully cured concrete, cement block and brick, masonry walls, cured cement mortar beds, cement backer units, exterior-grade plywood and gypsum wallboard, as well as spot bonding to common plumbing materials like stainless steel, copper and brass.
