About Waterproofing Membrane
A waterproofing membrane is applied beneath tile installations to create a continuous moisture barrier that protects substrates from water intrusion. Shower waterproofing membranes and tile waterproofing membranes are used in wet areas such as showers, tub surrounds, bathrooms, and floors where regular exposure to moisture occurs.
This collection includes liquid waterproofing membrane and sheet waterproofing membrane options designed to integrate into complete tile installation systems for residential and commercial applications.
Types of Waterproofing Membrane
- Liquid Waterproofing Membrane: Applied by roller, brush, or trowel to form a seamless waterproof barrier.
- Crack Isolation & Waterproofing Membrane: Products that combine moisture protection with movement accommodation.
- Reinforcement Fabric: Used at corners, seams, and transitions to strengthen waterproofing assemblies.
How to Choose
- Application Area: Confirm the membrane is rated for showers, floors, walls, or other wet areas.
- Installation Method: Liquid-applied membranes provide seamless coverage.
- Substrate Compatibility: Verify compatibility with cement board, drywall, concrete, or other substrates.
- System Integration: Choose products that work with your thinset, tile, and drainage components.
Common Applications
Waterproofing membranes are used in showers, tub surrounds, steam rooms, bathroom floors, laundry rooms, and other moisture-prone areas where tile is installed. Shower waterproofing membranes and tile waterproofing membranes are commonly specified for residential and commercial wet-area installations.
Why Use Waterproofing Membrane
Using a waterproofing membrane helps prevent water migration into wall cavities and subfloors, reducing the risk of mold growth, structural damage, and installation failure. A waterproofing membrane supports long-term tile performance and helps extend the life of the installation.
