Question 1

How much are Nurajacks?

Accepted Answer

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.

Question 2

How much weight can a Nurajack take?

Accepted Answer

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

Question 3

How many Nurajacks will I need?

Accepted Answer

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.

Question 4

Do I need to put a slip layer between the membrane and the Nurajack?

Accepted Answer

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.

Question 5

Will the Nurajack void the membrane warranty?

Accepted Answer

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.

Question 6

Are Nurajacks affixed to the membrane by screws or glue?

Accepted Answer

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

Question 7

What are holes in the bottom of the Nurajack base for?

Accepted Answer

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

Question 8

What type of paver or tile can I put on a Nurajack?

Accepted Answer

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.

Question 9

What type of joist or bearer can I put on the Nurajack?

Accepted Answer

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.

Question 11

Do Nurajacks have to go over a membrane?

Accepted Answer

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

Question 12

How do I use the Nurajack around the perimeter of a tiled deck?

Accepted Answer

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.

Question 13

Is the Nurajack System BRANZ or CodeMark appraised?

Accepted Answer

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