Since 2005, gluing tiles to membrane decks has been prohibited according to page 54 of the E2/AS1 compliance document of the New Zealand Building Code. 

Featuring a large base and the ability to self-level up to five percent, Nurajacks are guaranteed not to damage any sheet-based membrane (load limits apply).  Tiles directly on pedestals are the most cost-effective solution for tiled decks.


Nurajacks allow the tiles to be raised up to the level of the interior living space creating a level threshold with optimum indoor/outdoor flow. The Nurajack system does not use adhesives and grout and as the tiles are "floating", a tile can be removed at any time for the substrate or drainage outlet to be inspected.

Nurajack SE

Available in sizes from 28mm to 550mm, the adjustable Nurajacks incorporate a self-levelling head to protect membranes, making installation quick and easy. The bi-component head minimises reflective echo and improves foot feel. The large 220mm diameter base distributes the load over any waterproofing protecting the membrane from the load applied.

Nurajack Star.T

Starting at a height of 8mm, the Nurajack Star.T can be adjusted up to 15mm.


The Nurajack Star.T is150mm in diameter and is  levelled using a Star.T Slope Corrector.  Additional Star.B bases extend the height in 5mm increments - to a maximum of 30mm.


A wide variety of accessories are available to simplify installation and overcome most onsite challenges.

In some extreme situations, tiles may need to be affixed to the Nurajack. The Nurajack SE Windproof is a pedestal especially designed for areas in direct exposure to high winds. When parapets and balustrades do not provide enough protection, the Nurajack SE Windproof pedestal provides the solution.

See pages 8 and 9 of the Nurajack brochure for more information.

Nurajack Tile & Paver Installation





Tiles, pavers and timber decking all expand and contract depending on the exterior temperature. If a tile or paver is direct glued to a substrate, expansion joints are required. Nurajacks remove this requirement as the individual pavers are able to expand and contract without affecting the surrounding structure. However, the New Zealand Building Code requires a gap at the perimeter of a tile/paver or timber deck. Nurajack Tile Cladding Spacers can be used to interface between the edge of the deck and the building structure.



Tiles and pavers on Nurajacks do not have grout between them. This allows rainwater to flow between the tiles/pavers letting the waterproofing membrane to do its work, shedding water to the drainage. Another advantage is that the membrane is then able to breathe. Any excess moisture will quickly evaporate, ensuring that there is no long-term dampness around the membrane.



The unique self-levelling head of the Nurajack provides a level deck every time. With other deck jacks, tilers must resort to placing ad-hoc shims under the base of the jacks - a time-consuming practice that has the potential to damage the waterproofing membrane through point loading. With Nurajacks, the deck load is evenly spread on their wide base, ensuring stability and that the integrity of the membrane is maintained while the self-levelling head facilitates a level trafficable surface. Nurajacks can self-level up to five percent. 



Nurajacks feature a large 330 sq cm base to evenly distribute the full weight of the tile/paver or timber decking and whatever may be on top. This minimises any indentation that is evident with smaller based jacks. Nurajacks can withstand weights up to 1,000 kg, however, consideration must be given to the structure and the membrane before excessive loads (such as spa pools) are placed on the Nurajacks.



Nurajacks have a unique bi-component head. The heads feature an integrated rubber component that is designed to minimise tile vibration which reduces the reflective echo of the system when it is walked on. The rubber component also aids the installation as the tiles will not slide off the head or move around during installation.



As the Nurajack system is totally floated, there is no adhesive or fixing involved. All the tiles/pavers are removable for inspection purposes - as required by E2/AS1. An added advantage is that additional services can be run under the suspended tiles/pavers. When timber decking is fastened using stainless steel screws, the decking can also be removed for inspection of the membrane deck as required.


When tiles/pavers are installed over Nurajacks, the Nurajack Adjustment Key enables the tiler to complete the installation with perfect accuracy.  The Adjustment Key adjusts the height of the tiles from above, without the need to remove the tiles.  As a result, installation time is accelerated, and the laborious task of repeatedly lifting the tiles to adjust the pedestals is minimized.
