Anyone! Nurajacks for timber decks are not considered restricted work. Any DIY-er or tradesman should be able to install.

The calculations produced by the Quantity Calculator are based on averages and should be viewed as an estimation only.

Nurajacks are designed and manufactured in Italy.

The Nuraspike is designed in New Zealand and manufactured in Vietnam.

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.

The Nuraspike and Nurajack system is designed for low-profile decks less that one metre off the ground, which typically do not need a building consent.

However, the structure of the deck should be constructed as per local regulated requirements.

If a low-profile deck is constructed 'stand alone' away from a building, it is considered a landscape feature and is usually outside the Building Code.

Please consult with your local governmental authority for more information.

Nurajacks are part of the Nuralite Membrane Deck Branz and Codemark Appraisal.

As yet the Nuraspikes do not have an appraisal.

This depends on the dimensions of the deck area - please use the QUANTITY CALCULATOR.

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

Nurajacks can be installed over any stable, non-eroding surface.

Nuraspikes are used when installing over grass or dirt, where stability or erosion could be a factor.

Nuraspikes should not be used if there is a layer of rock within 500mm of the topsoil.

If there is a layer of rock, remove the soil and place the Nurajacks on top of the rock base.

Nurajacks have been load tested up to 1000kg.

A laser level is the easiest way.

Another technique would be to use a straight edge, making it level and measuring the distance under the straight edge where you expect your Nurajack to be (remembering to deduct the buildup of the deck).

NO!!! Nurajacks simply rest on the membrane. Gravity and the surrounding walls/parapets/balustrades hold the deck in place.

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.

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

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.

An offcut of the membrane used on the project can often act as a slip layer.

Most membrane suppliers provide a Materials Defects Warranty so 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 or adhesion to the membrane.

No, the 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.

This is dependent on the design of your deck.

Nuraspikes are a decking pile replacement - so wherever a pile should go is typically where a Nuraspike should go.

Please see the Quantity Calculator to help design your deck and the placement of the Nuraspikes/Nurajacks.

Much depends on the ground that the Nuraspike is installed into. We have tested the Nuraspike in grass and dirt to 500kgs each and observed zero movement over a 3-month period.

This is dependant on the design of your deck.

Nuraspikes and Nurajacks can be placed directly under a joist or bearer.

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.

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-levelling head and can be placed anywhere on top of the Nuraspike.

This means the Nuraspike can generally be 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.

Yes, however, the Nuraspike is made from Galvanised Steel which has been powder coated and will continue to give adequate support of the Nurajack deck for more than 20 years.

In very acidic soils - such as in volcanic locations - traditional pile construction should be considered.

No, Nurajacks cannot be cross braced, limiting decks to less than 1000mm in height.

Where bracing is required, use either brace or anchor piles.

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 1000mm off the ground at its highest point.

Consider the cost of the products, the time costs required for a traditional piles, 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.

Each Nurajack can withstand a load up to 1000kg.

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 wind loading.
