Waterproofing & Uncoupling Membrane

Moisture Control and Movement Management for Tile Installations

Waterproofing and uncoupling membranes are used to manage moisture, prevent substrate-related movement, and protect tile installations from failure. These products are installed beneath tile assemblies to control water intrusion, isolate cracks, and improve long-term performance on floors, walls, and wet-area applications. This category includes membranes and supporting accessories designed to integrate into professional tile installation systems.
