Pad foundations can be selected as they do not require much excavation, and are generally suitable where the bearing capacity of ground is sufficient at relatively low depths. However, they can be large in plan shape and may not be effective against differential settlement, uplift forces or wind forces.

How deep should pad foundations be?

1 mFor low-rise buildings, it is generally recommended to limit the overall depth of a pad foundation to 1 m from ground level. When designing the pad, care should be taken to ensure that it is large enough to prevent tension within the concrete, which could result in cracking and failure.
