Building Column and Pad Forms

Column and pad forms are among the simplest concrete projects. They warrant careful planning, however, because these small pieces of concrete provide essential support for decks, wood stairways, and outbuildings.

Any outdoor structure that connects to your house should have footings that extend below the frost line. Otherwise, frost heave will stress the junction between the house and the structure and lead to serious damage. Where frost is not a problem, you usually are safe excavating to a depth of 24 inches.
