What Are Pad Foundations?

Pad foundations are placed under structures that have one or more columns in order to provide support. Most of the time, they are square or rectangular in shape.

The size and thickness of pad foundations are dependent on the load caused by the columns. The thickness of the pad may vary to help provide additional support. For instance, the pad foundation may be thicker at the center and slope thinner to the outside.

Pad foundations are most often made of concrete. They can be formed into strips to provide support to columns that are placed closely together as well as free-standing walls.
