    Frequently Asked Questions

    What types of waterproofing membranes are available for tile installations?
    We offer both sheet and liquid-applied membranes. Sheet membranes like those from GoBoard and wedi provide fast, consistent coverage, while liquid membranes such as USG Durock offer flexible application around corners and irregular surfaces.
    Are these membranes suitable for use behind tile in showers?
    Yes, all the membranes in this collection are ideal for shower walls, pans, and wet room installations. Options from GURU USA and wedi are especially popular for waterproofing under tile.
    Can I use these membranes on floors outside of wet areas?
    Definitely. While designed for wet areas, many waterproofing membranes also protect bathroom, laundry room, and kitchen floors from spills and moisture, making them a smart choice for broader floor prep.
    What surfaces are compatible with liquid waterproofing membranes?
    Liquid-applied membranes, like those from USG, work on concrete, cement board, masonry, and other properly prepared surfaces. They’re a versatile solution for irregular shapes and detailed waterproofing.
    Is it necessary to use a waterproofing membrane with a pre-sloped shower pan?
    Yes. Even with a pre-sloped pan, waterproofing the walls and seams is critical. Pair your shower base with a compatible sheet membrane from wedi or GoBoard for complete protection.
