Deck Jacks & Council requirements

Recently councils have insisted that floating deck surfaces should be removable to allow access to the waterproofing membrane below.

When constructing a floating deck or patio paving, it is now necessary to allow the paving tiles or floating timber decking to be easily removed in future if necessary, and, being height adjustable, they allow the tiles or decking to be raised up to the level of the living space to create the desired indoor/outdoor flow. The range to use is our Pro-Jack system.

The unique feature of our Pro-jack is its self-levelling head. No deck is built level - the underlying slope and membrane lap-joints challenge the best tiler. With other deck-jacks they must resort to placing ad hoc shims under the base of the jacks. This has the potential to damage the membrane through point loading. With Pro-jacks, clients get a level deck every time. The deck load is evenly spread on the Pro-jack’s wide base, ensuring that the integrity of the membrane is maintained, and that the unit remains stable under loading.

Pro-jacks are made from high density polypropylene injection moulding. They are age and weather resistant and fully compatible with all roofing materials.

Laying a patio paving floor with Pro-jack supports is straight forward. The jacks simply rest on top of the waterproofing membrane or any other surface due to be paved, and the paving tiles sit into the corners of the Nurajacks. Following an initial rough adjustment, laying the chosen paving is made easier by the self-levelling head. The adjustment key is then used to complete the installation with millimetric accuracy.

The void between the paving and the waterproofing membrane underneath can be used to accommodate pipes and other systems, which are thus concealed and yet can be easily accessed if necessary.

Adding an acoustic shim is a cost effective way to enhance the acoustic reduction properties of the system.

Tile Warehouse’s 20mm thick tiles are a full-bodied porcelain. They are suitable for heavy commercial use such as squares, balconies, subways, airports, parking lots, gardens, walkways and parks. We have an extensive range which can be viewed here >>>

Tile Warehouse’s 20mm tile ranges comply with the recent Auckland City Council’s Amended Practice Note for external and internal membranes (Document number: AC2234, version 3). This document states that when tiles are to be laid outdoors, they must be laid over a floating deck, which must provide adequate clearance for ventilation purposes and not be permanently fixed to the membrane.
