Bathroom Waterproofing Membranes
Protection That Lasts
Water damage doesn't announce itself until it's too late. The right waterproofing membrane for your bathroom is your first line of defense against costly callbacks, failed inspections, tiling and structural issues that can haunt a job for years.
Gripset 38FC
A flexible cementitious membrane that's become an industry standard for good reason. Bonds directly to concrete, cement sheet, and masonry without primers in most applications. Handles substrate movement without cracking, making it ideal for timber-framed wet areas. Simple trowel or brush application means your team can work efficiently without specialised equipment.
Ardex WPM 155 Rapid Plus
When the schedule's tight, Rapid Plus delivers. Fast-curing formulation gets you to tiling sooner without compromising waterproof integrity. Excellent adhesion to a wide range of substrates, plus the flexibility to accommodate normal building movement. Suitable for internal wet areas including showers, bathrooms, and laundries.
Siegel Pro25
Professional-grade protection engineered for demanding applications. Superior crack-bridging capability handles substrate stress without membrane failure. Applies smoothly for consistent coverage and bonds aggressively to prepared surfaces. Meets Australian waterproofing standards with proven performance in thousands of installations.
Get It Right From the Start
Every bathroom waterproofing job needs proper surface preparation, correct application techniques, and membrane selection that matches your substrate and conditions. These aren't products where "close enough" cuts it—waterproofing either works or it doesn't.
Our team can walk you through technical specifications, coverage rates, and application requirements for your specific project. Because the best time to prevent water damage is before the tiles go down.
