Undertile Waterproofing Solutions

When you’re building a new bathroom, shower, laundry, kitchen or other wet area, or renovating, it’s vital to ensure that the floor under bathroom and shower tiles is effectively waterproofed from the outset to stop moisture getting between tiling and substrate. Any seepage can result in structural damage that is expensive to fix.


We work with architects, building contractors, homeowners, and landlords to provide undertile waterproofing solutions matched to the particular requirements of each project. 


We are licensed building practitioners and have a team of sub trades available, so talk to us about taking care of your entire bathroom installation or renovation, including project management and council consents.
