Waterproofing is the foundation of any successful wet-area installation. Done correctly, it prevents costly water damage, mould, and structural deterioration for the lifetime of the building. Done incorrectly, the results can be catastrophic.
JSR Tiling takes waterproofing seriously. We use BRANZ-appraised membrane systems, apply them correctly to manufacturer specifications, and inspect every installation before proceeding with tiling. Our waterproofing track record — zero callbacks in 15 years — speaks for itself.

Waterproofing Questions
Is waterproofing required under tiles in NZ?
Yes. Under the NZ Building Code (E3), waterproofing is required in all wet areas including showers, baths, and adjacent floor areas. For commercial projects, this is a compliance requirement.
What waterproofing systems do you use?
We use BRANZ-appraised liquid-applied membrane systems from reputable manufacturers. The specific product is chosen based on the substrate and application — we will specify the appropriate system during quoting.
Do you provide a guarantee on waterproofing?
Yes. Our waterproofing installations come with a workmanship guarantee. Many of the membrane products we use also carry manufacturer product warranties.
Can you waterproof balconies and decks?
Yes — balcony and deck waterproofing is a significant part of our work. We use trafficable membrane systems suitable for tiled balcony applications with correct falls to drains.
