How to achieve Min & Max Top/Bottom of Joist heights PDF
The Patio Deck Kit and Optional Patio Deck Kit Height Adjuster have now been released into the Australian market around. It will take time for the Timber Merchants and Hardware stores to become aware of the product and to receive stocks. If they don't have stock, they can order the product in from our distributors and have stock within a few days.

The Patio Deck Kit Height Adjuster is an optional add-on, and only works in conjunction with the Patio Deck Kit which just clips onto the underside of the Nylon Base Plate.
Patio Deck Kit -contains 9 x Aluminium Joists @ 1,000mm (39.6 inches) long, 36 Nylon Base Clips and 9 end-caps to provide the finishing touch.
Optional Patio Deck Kit Height Adjuster- contains 36 Base Pieces and 36 Top Pieces.
Note: For every box of the Optional Patio Deck Kit Height Adjuster you will need one box of the Patio Deck Kit.
Australia/NZ: approx. 3.8 sq metres with joists @ 450 mm centres
USA: approx. 35 sq feet with joists @ 16 inch centres
These are approximate coverage only and depends on your exact deck area dimensions. If you require exact coverage work out the number of aluminium joists required, then you need to work out the number of "joists spacings" along your deck and remember to add one for the initial joist.
IF IN DOUBT - DRAW A SMALL DIAGRAM AS SHOWN BELOW WITH THE DIMENSIONS OF YOUR DECK.
IN THIS EXAMPLE YOU HAVE 12 ALUMINIUM JOISTS @ 4.5 metres long = 54 metres. EVERY BOX OF PATIO DECK KIT CONTAINS 9 x 1 meter Length ALUMINIUM JOISTS
SO YOU WILL REQUIRE 6 X BOXES PATIO DECK KIT and 6 X BOXES OPTIONAL PATIO DECK KIT HEIGHT ADJUSTER (if adjustment is required)
35mm fixed ( 1.4 inches) Snap-Loc clip adds 4mm = total 39 mm
Gives a minimum height increase of 12mm (approx. equal to a 1:100 “fall” over a 1 metre length), resulting in a “top of joist” height of 46mm, and allows the Patio Deck Kit aluminium joist to be adjusted in small increments to a maximum top of joist height of 65mm. This is perfect for either raising your whole deck, or for taking the “fall” out of your concrete slab.

1000 mm Long x 30 mm Height x 40 mm Width x 2 mm in thickness
Approximately every 330mm (13 inches)
Nylon Base clips provide 4mm clearance over your concrete /tiled area.
Maximum Australia/NZ 450mm or 16 inches for USA
Provided you don't have a membrane to contend with, for all end joists or end of section joists (eg where breaker boards are used), its good practise to secure the base clips with 8mm masonry anchors at both joist ends. For the remaining Base clips between both joist ends, these can be fixed to the concrete using approved adhesives..
Soudal T-Rex Power Flexi or Fast Grab SMX adhesive.
When building decks low over concrete, it is important to use the most stable decking products – the new generation “capped” composite decking boards are ideal for use in this type of situation as the capping greatly increases moisture resistance.
Of the conventional timber types – merbau is an extremely stable decking and is suitable for most situations, however its “bleeding” characteristics can be problematical. Many of the Australian hardwoods are great timbers, however it is advisable to get an opinion from the “manufacturer” regarding their suitability in your specific situation, especially if you were considering using wider (eg 140mm) decking boards.
Fixing to aluminium joists is substantially the same as fixing to steel joists.
For composite boards, install as per manufacturer regulations for installation with steel joists.
Note – a great way to fasten (ModWood and Trex) boards down is to use the KlevaKlip Snap-Loc concealed fixing system. The clips can be adhered to the Aluminium joists using Soudal “T-Rex” adhesives, so no screws or nails at all are needed for your deck – then just walk the boards in. The easiest way you will ever lay a deck!

Should you decide to use timber decking, pre-drill and countersink the timber before fixing with galvanised steel “tek screws” (use Stainless steel in high corrosion areas). It's a good idea to discuss suitability and installation with your decking supplier.
Soudal T-Rex Power Flexi or Fast Grab SMX adhesive. Please note it is essential to prime the top of the aluminium joists with Soudal Surface Activator. Wait 10 minutes before applying approximately 6mm bead of Soudal adhesive to the middle of the aluminium joists.
Pre-drill before using Galvanised "tek" screws 10 G 30-40 mm. (use stainless steel in high corrosion areas)
For both Timber and Composite Decking a minimum gap of 5-6 mm is required to assist ventilation.
In these areas, as a minimum you need to secure every second base clip to your concrete with an 8 mm (5/16 inch) masonry bolt, plus all aluminium joists should be secured to the base clips via 8 gauge self-drilling tek screw on each side of the joist
8mm (5/16) masonry bolt or screw anchor
