Auckland Council Requires Floating Tile Systems for Decks – What This Means

Why Councils Require It

Floating systems are now the go-to method for raised decks in Auckland, and there’s good reason behind it.

• It complies with the New Zealand Building Code for waterproofed areas.

• It prevents trapped moisture and membrane damage — a common issue with traditional tiling methods.

• It allows individual tiles to be lifted for inspection or repairs.

• It holds up well outdoors, especially in Auckland’s weather conditions.

For any deck that sits over a waterproofed area — like a first-floor balcony or rooftop terrace — this system isn’t just smart, it’s mandatory.

What Kind of Tiles Can Be Used

Not all tiles are suitable for floating systems. Nurajack and other pedestal manufacturers specify that only structural-grade tiles or pavers should be used.

For porcelain tiles, that usually means options in the 14 mm, 20 mm or 30 mm range.
If you’re working with stone, it needs to be a dense, homogeneous type — typically 35–40 mm thick to handle the load.

At Ray Tiling, we can help you choose suitable tile products that meet system specs and perform well in Auckland’s conditions.

How We Do It Right

We’ve installed floating tile systems across decks, balconies, and rooftop areas. Our approach is council-compliant, weatherproof, and focused on long-term durability. We use reliable systems like Nurajack and we always work in line with local waterproofing standards.

If you’re investing in a tiled outdoor area, especially one that involves waterproofing or council consent, we’ll make sure it’s done the right way — from the first layer up. Check out the video below of a jack tile project in progress!
