Build a deck - planning and footing
A deck can transform your backyard by creating a fantastic outdoor entertaining area that the whole family can enjoy.
In this step by step video series, we take you through the whole process of building a deck from designing the deck to finally laying the boards.
In Part 1, we explain how to plan the deck, starting with the footings.
A deck needs to be supported by a footing, and the size of the footing is regulated by the local council based on the type of soil in your area.
After setting out the shape of the deck, you’ll need to mark the position of the footings on the soil, then excavate the area, digging holes for the footing.
You’ll need to calculate how much concrete you’ll need for the footing. It’s best to order pre-mixed concrete as it’s less effort and not much more expensive than mixing it yourself
There are two types of post supports. One sits in the wet concrete, while the other bolts to the top of the dry footing.
If you’re building a deck off the back of a house, you’ll need to attach the deck to a ledger that’s attached to the wall at the same height as the bearers.
