Containing water within the shower assembly is critical, and inconsistent waterproofing can lead to failures at seams, corners, and transitions. DMX Waterproof Mat is a flexible, sheet-applied membrane designed to create a continuous waterproof barrier behind tile. It can be installed directly over drywall in standard residential shower applications, offering a streamlined alternative to backer boards that reduces material, weight, and installation time while maintaining reliable waterproof performance. It integrates with the full DMX Shower System, helping ensure consistent, long-term protection when properly installed.
