GURU Waterproofing Membranes for Tile & Wet Areas

GURU Waterproofing Systems provide membranes, uncoupling products, banding, preformed accessories, penetration seals, and sealants for creating compatible waterproof tile assemblies. Available products include waterproofing membrane, uncoupling membrane, waterproof banding, corners, drain flashing, pipe seals, mixing valve seals, and related accessories for showers, bathrooms, and other wet-area installations. Product functions, substrate compatibility, and installation requirements vary by component.

Types of GURU Waterproofing Membranes

Waterproofing Membrane

GURU waterproofing membranes provide a waterproof layer beneath compatible tile installations on walls, floors, and other approved wet-area surfaces. Banding, corners, and related accessories maintain waterproofing continuity at seams, transitions, changes in plane, and other installation details.

Uncoupling Membrane

GURU uncoupling membranes provide a separation layer between compatible substrates and tile coverings to help manage stresses caused by differential movement within the assembly. Waterproofing capabilities and installation requirements depend on the specific membrane and system configuration.

Waterproofing Accessories

Drain flashing, pipe seals, mixing valve seals, sealants, and other accessories address penetrations and transitions within compatible waterproofing assemblies. Components should be selected according to the specific membrane, substrate, fixture, and installation detail.

Choosing GURU Tile Waterproofing Products

Choose GURU waterproofing components according to the installation area, substrate, waterproofing or uncoupling requirements, seams, transitions, drains, and plumbing penetrations. Verify compatibility between membranes, banding, preformed accessories, sealants, and other required components before selection.
