Footing Requirements. At the same time as your slab is poured, you will also need to pour perimeter footings, as illustrated below. This is called a monolithic pour or monolithic slab. Perimeter footings should be 12â³ wide, and 12â deep.or example, if you have purchased a 20â² wide by 40â² long building, your slab should be 20â² wide by 40â² 2â³ long. Your floor should be a minimum of 4â thick. The concreteâs strength should be a minimum of 2500 psi, with fiber mesh reinforcement added at the batch plant OR #3 rebar on 24â centers.
