Footing Trenches
The trench must be dug deep enough to reach firm, undisturbed soil. For light buildings in warm climates, this may be as little as 30cm. However, for large, heavy buildings footing trenches may need to be up to 1m deep.
Pockets of soft material should be dug out and filled with concrete, stones or gravel. The trenches should be free of standing water when the concrete is poured for the footing.
