Waterproofing Membranes

KERDI Membrane and Aqua Defense are both advanced waterproofing solutions designed for use in various construction and remodeling applications, particularly in wet areas like showers and bathrooms.

KERDI Membrane

Schluter KERDI Membrane is a polyethylene waterproofing membrane that acts as a vapor barrier, preventing moisture penetration and protecting underlying structures from water damage. Its lightweight, flexible design allows for easy installation and integration with Schluter's KERDI system. KERDI Membrane is compatible with thin-set mortar, ensuring a secure bond with tiles and providing a reliable, long-lasting waterproof barrier. It is ideal for use in shower assemblies, on walls, floors, and other areas where water exposure is a concern, effectively preventing mold and mildew growth.

Aqua Defense

Aqua Defense, produced by Mapei, is a liquid-applied waterproofing membrane that provides excellent protection against water infiltration. This polymer-modified membrane can be easily applied with a brush, roller, or spray, forming a seamless, flexible barrier upon curing. Aqua Defense is suitable for a variety of substrates, including concrete, cement board, and drywall, and it is particularly effective for areas subject to high moisture, such as showers, kitchens, and balconies. Its quick-drying properties and outstanding adhesion make it an efficient choice for both professional and DIY installations.
