Nurajacks have been load tested up to 1,000 kg.

Any timber, aluminium or composite bearer can be installed on a Nurajack. Make sure the bearer is suitable for the loads to be applied. Aluminium joists can span greater distances than timber or composite joists. Nurajack recommends Outdure for aluminium joists.

The Tiles and Pavers must be designed for pedestal systems. Typically they are called Structural tiles or pavers. In Tiles, they can range in thickness from 14 mm, 20 mm and 30 mm thick. Stone typically needs to be a homogeneous variety and 35-40 mm thick and Concrete typically needs to be 50 mm thick (often requiring a reinforcing layer and rectifying so is square). Check with your paving/tile supplier as to suitability for a pedestal system.

Nurajacks are available from most Timber Merchants and Tiles Stores around NZ. Ask for them by name. Nurajack pricing varies depending on the size of the Nurajack required.

Check the specification to see if a slip or separation layer is required for your particular project. The self-levelling head of the Nurajack ensures the Nurajack is fully supported over the membrane. Also, Nurajacks have been fully tested over Nuralite membranes proving that there is no need for a slip layer. HOWEVER, many other membrane suppliers specify a slip layer under a pedestal on their membrane. If a slip/separation layer is required, use the Nurajack Acoustic Separation pad under each Nurajack.

The tabs on the top of a Nurajack Tile Head are removable. If opposing tabs are removed, tiles can sit side by side to dully support the edge of the tile. The Base of the Nurajack is designed to be cut down so the head can sit as close to the wall as possible. See the installation video on tile and paver instillation in our Video Resources.

No. Most membrane suppliers provide a Materials Defects Warranty. Their warranty does not cover any damage caused by other products or items impacting on their membrane. Nurajacks are compatible with all sheet membranes (e.g. Butyl, TPO, Bitumen etc.) and are installed without penetration of the membrane and will not damage the membrane.

They are a legacy from an older system and serve no other purpose.

No! Nurajacks simply rest on the membrane, gravity and the surrounding walls/parapets/balustrades hold the deck in place.

No. Nurajacks can be installed over any stable, non eroding surface. If installing over grass or dirt, use a Nuraspike.

This depends on the dimensions of the deck area - please use the Quantity Calculator. If you are struggling with estimating the quantity of Nurajacks required, please contact one of the Nurajack team.

Yes. Nurajacks are part of the Nuralite membrane appraisal framework.

Expect to pay around $45 Inc GST. Nuraspikes are available from Timber Merchants such as PlaceMakers, Bunnings, ITM, Carters, Build Link.

We have tested the Nuraspike in grass and dirt up to 500 kg each and observed zero movement over a 3-month period.

Nurajacks are part of the Nuralite Membrane Deck BRANZ and CodeMark Appraisal. As yet the Nuraspikes do not have an appraisal.

Each Nurajack can withstand a load up to 1000 kg. Check that the soil is stable enough for the loading of the spa pool or shed. Consider the need to restrain the shed in the event of a seismic event or in high wind.

This is dependant on the design of your deck. Nuraspikes are a decking pile replacement - so wherever a pile should go is where a Nuraspike should go. Please see the Quantity Calculator for more information.

Some gradient of slope is acceptable. You may have to remove the grass so the top of the Nuraspike is flush to the dirt. However, the deck will not be able to extend more than 1000 mm off the ground at its highest point.

Consider the cost of the products, the time costs required for a traditional pile, the delay of the project while the concrete cures and the clearing away of removed soil. The Nuraspike is considerably cheaper, cleaner and more efficient than a traditional pile.

No. Nuraspike will not work in waterlogged or excessively rocky soils. We recommend that you test the soil by driving a Nuraspike in first before committing to purchase all the Nuraspikes needed for a project.

No. Nurajacks cannot be braced, so we limit Nurajack decks to less than 1000 mm tall. Where Bracing is required use either brace or anchor piles.

No. The Nurajack just sits on the Nuraspike. This allows for any movement (expansion or contraction) of the deck. If the deck will be subjected to lateral forces, affix the deck to the house foundation or utilise a locating pile.

Nurajacks are the secret to the Nuraspike. The Nurajacks have a self-leveling head and can be placed anywhere on top of the Nuraspike. This means the Nuraspike can be generally lined up with the other Nuraspikes along a joist or bearer line - the Nurajack will affix to the joist or bearer and sit on the Nuraspike.

The Nuraspike and Nurajack system is designed for low-profile decks less that 1 meter off the ground, which typically do not need a building consent. However, the structure of the deck should be constructed as per NZS3604 or to local regulated requirements. If a low-profile deck is constructed 'stand alone' away from a building, it is considered a landscape feature and is outside the building code.
