A footing is what the exterior walls of the building sits on. The footing disperses the weight of the building over a wider area and helps prevent settling. There are two main types of footings; spot footings, which the posts of a building or a pier would sit on, and continuous spread footing, which the frame of the building would sit on. This allows the footings to step up or down in 8-inch increments, which work with 8 inch high concrete blocks. You can see how this works in the pictures above. You may have a situation where an 8-inch footing step is too much. Concrete blocks are also made 4 inches high, and are commonly called "half-highs." These work well with 4-inch footing ...
