- Use Hardwood timbers that are Durability class 1 and 2 above ground. All Deck-Max™ hardwood decking meets this criteria.
- Bamboo and Composite decking materials are in a different class however the materials made by Deck-Max™ meet all standards.
- Decking boards should be seasoned to the requirements of the applicable Australian Standard (i.e. Hardwood 10% to 18%, ) Note: TQL recommends a maximum MC of 15% for residential decking.
- Refer to your local ambient city guide – this will provide you with the ambient (the local city moisture content recommended) moisture content recommended in the timber before laying, preferably before delivery. Your decking supplier can provide you with:
- Local ambient moisture content for your city / town / region
- Moisture content of the material at store level. Note: it will change in transit and when it arrives on site at which time it will achieve the ambient moisture content for your area.
- Grading of Wood is based on Australian standards of AS 2796, that will provide you with what is referred to as Standard and Better in reference to outdoor decking. This will provide you with some inconsistencies of colour, knots, holes and all the natural attributes of hardwood.
