What Is a Footing in Construction?

A footing is a part of the foundation that helps support the foundation so that the structure does not settle. It is typically made of concrete with rebar reinforcement. The depth and width of the footing depends on the type of soil and the size and type of the foundation.

Footings may also be required for retaining walls or decks. Footers spread the building's weight to a larger surface. They are usually 8 to 10 inches thick, whereas the average foundation is about 8 inches thick. It also makes the surface flat so it is easier to work on the structure.
