Waterproofing Accessories for Tile & Shower Systems

Waterproofing accessories are used to seal seams, corners, penetrations, and transitions within tile waterproofing systems. These components help maintain continuous moisture protection around plumbing fixtures, drains, wall-to-floor transitions, shower curbs, and other areas where waterproofing membranes require supplemental sealing.

This collection includes waterproofing bands, sealing tape, inside and outside corners, pipe seals, pipe collars, mixing valve seals, waterproofing patches, curb covers, and sealants used in residential and commercial shower waterproofing and wet-area tile installations.

Types of Waterproofing Accessories

  • Waterproofing Bands & Sealing Tape:Ā Used to reinforce seams, membrane overlaps, and change-of-plane transitions.
  • Inside & Outside Corners:Ā Preformed waterproofing corners designed to simplify corner detailing and improve waterproof coverage.
  • Pipe Seals & Pipe Collars:Ā Used to waterproof plumbing penetrations for shower heads, supply lines, and other fixtures.
  • Mixing Valve Seals:Ā Designed to waterproof valve openings behind shower trim assemblies.
  • Sealants & Waterproofing Patches:Ā Used to reinforce waterproofing details, repair membrane damage, and seal critical transitions.

Waterproofing Details Around Plumbing Penetrations

Pipe seals, pipe collars, and mixing valve seals are commonly used around plumbing penetrations where moisture intrusion can occur if waterproofing continuity is not maintained.

Selecting Waterproofing Accessories

Selecting the correct waterproofing accessories depends on the membrane system being used, the location being sealed, and the specific waterproofing detail required within the installation.
