Do you need footings for a garden wall? In many cases low walls are installed with a sand or gravel foundation that helps level stones and provide needed drainage around the base. However, in some cases a shallow concrete footing is needed, especially if you want to cement the base in place to ensure stability.
How deep should footings be for a garden wall? For a wall that will be higher than 750mm make the footing three times the thickness.
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.
