Waterproofing is the system behind the finish. A shower can look perfect on day one, but long-term performance depends on how well you tie together seams, corners, curbs, and penetrations before tile ever goes up. This Waterproofing Solutions collection brings together the core building blocks tile installers need to assemble a reliable wet-area system—without hunting for the “one missing piece” mid-job.

What’s in this collection

  • Waterproofing membranes & liquid options: Primary barrier products used on walls, floors, and wet-area details—choose based on your workflow and the surface you’re building over.
  • Seam, corner & penetration accessories: Inside/outside corners, seam tape/banding, and collars/seals that make it easier to waterproof the high-risk areas (changes of plane, mixing valves, pipe penetrations).
  • Curbs, fasteners & install add-ons: Pre-formed curb options and system hardware/accessories that help connect transitions and keep assemblies clean and consistent.

How to choose

  • Sheet membrane vs liquid: Sheet systems can be fast and consistent for broad coverage; liquid systems can be great for odd shapes and tight details. Choose what matches your crew and job conditions, and follow the manufacturer’s install instructions.
  • Plan the “failure points” first: Corners, seams, curbs, and penetrations are where showers fail—make sure you have the right accessories on hand before you start.
  • Match components for compatibility: When possible, keep waterproofing components within the same system (or confirm cross-compatibility) so adhesives, tapes, and accessories work as intended.
  • Don’t skip substrate prep: Waterproofing can’t compensate for loose, dirty, or unstable surfaces—prep and flatness still matter for a clean tile install.
