MAPEI MEMBRANES & UNDERLAYMENTS
Create a solid foundation for any flooring or tile installation with Mapei underlayment membranes, trusted by professionals worldwide for their durability, performance, and advanced protection. At Sapphirus Stone & Tile Inc., we proudly supply a wide range of Mapei membranes designed to enhance tile and flooring longevity by providing essential functions such as crack isolation, waterproofing, vapor control, and sound reduction.
Whether you're working on a residential bathroom remodel, a large-scale commercial space, or a heated floor system, Mapei’s industry-leading membrane technology ensures your finished surface performs at its best for years to come.
Mapei’s membranes like Mapeguard UM and Mapeguard CI are engineered to protect tile and stone installations from in-plane substrate movement. These crack-isolation membranes absorb stress and movement from subfloors, helping to prevent cracks from transferring through to your tile surface. They also serve as excellent uncoupling layers over challenging substrates such as plywood, concrete, or radiant-heated floors.
For areas exposed to moisture—such as bathrooms, kitchens, and basements—Mapelastic AquaDefense and Mapeguard WP deliver premium waterproofing protection. These membranes are easy to apply and compatible with a wide range of adhesives and mortars. They meet ANSI A118.10 standards and are perfect for shower systems, wet rooms, and exterior balconies.
Additionally, membranes such as Mapeguard 2 offer moisture vapor emission control, making them suitable for use over concrete slabs with high moisture content, which is especially important in below-grade installations.
Need noise control for multi-family or high-rise installations? Mapei offers membranes that provide effective impact sound reduction without compromising performance. These are ideal for condo flooring and commercial applications where acoustic comfort is a priority.
All Mapei membranes are designed with the installer in mind. They are lightweight, easy to cut and handle, and compatible with most Mapei mortars and adhesives. Whether you're using sheet membranes, roll-out mats, or liquid-applied waterproofing, the system integrates seamlessly into Mapei’s comprehensive floor and tile installation solutions.
