Waterproofing Membranes

Waterproofing membranes form the primary barrier that protects building substrates and occupied spaces from water ingress. Adheseal’s Waterproofing Membranes collection is the main hub for liquid, cementitious and sheet systems used across bathrooms, showers, balconies, decks, roofs, basements, retaining walls and structural waterproofing.

Shop waterproofing membranes by type

• Liquid waterproofing membranes: brush-, roller-, spray- or trowel-applied systems that cure into a continuous seamless barrier.
• Cementitious waterproofing membranes: polymer-modified cement systems for concrete, masonry, wet areas, tanks, pools and below-ground work where specified.
• Sheet waterproofing membranes: prefabricated PVC, butyl and WeldTec systems for roofing, wet areas, tanking and structural waterproofing.
• Self-adhesive sheet membranes: cold-applied butyl systems for protected structural and under-finish applications.
• Trafficable waterproofing membranes: systems selected for exposed balconies, decks, roofs and podiums where foot traffic forms part of the specification.

For an exposed deck, podium or roof needing a specified walking surface, start with the Trafficable Membranes collection. It distinguishes primary waterproofing membranes from protective and wear coats, including Gripset and SILCOR system components.

Choose by application, exposure and complete system

Internal wet areas require compatibility between the substrate, primer, membrane, joint detailing, tile adhesive and finish. Exposed roofs and balconies may require UV stability, early ponding resistance or a specified protective trafficable coating. Below-ground waterproofing can introduce hydrostatic pressure, soil contact, root resistance, protection and backfilling requirements.

Do not select by chemistry alone. Check the current manufacturer technical data for approved substrates, coverage and film thickness, cure times, reinforcement, UV exposure, immersion, traffic classification, primers and compatible finishes.
