How deep do the footings have to be?
Footings need to be minimum 1m deep by 600mm wide.
How deep should footings be for a 6 foot wall?
All footings should be a minimum of 150mm (6″) in depth, with the bottom 350 – 400mm (14-16″) below ground level on most soils. For clay soil however, thicker and deeper footings should be used.
How long do footings take to set?
If you use a concrete that has a quick setting additive you need to wait a minimum of one sunny day, if you are using a standard concrete footing mix I would recommend waiting for a minimum of seven days and a maximum of 28 days, of course, that is if the conditions are right for the concrete to cure and set hard .
Are houses on stilts safe?

Admittedly, much of the damage to stilts or pilings we see is because of repeated water exposure, but there are other causes. The two primary types of stilts found in our area are pressure treated wood or concrete.
