How deep should footings be in Wisconsin?

Why is it necessary to step footings on a sloping site?

Footings, the concrete pads upon which foundation walls are built, must be located beneath the frost line in order to prevent a building from heaving when the ground freezes. If the site is sloped maintaining a constant elevation for the footings would either cause the footings to be above the frost line or significantly deeper than the frost line at one end of the building. Stepping the footings enables them to follow the slope of the site and remain below the frost line without going too deep under the ground. It allows the foundation wall heights to be minimized because the footings are kept as close to the surface as possible.

How to Construct Proper Footings for Your Deck?

A well-constructed deck must have proper footings in order to be stable and secure. Make sure to dig your footing holes deep enough so that they are on undisturbed soil and sit below the deepest point of frost penetration. Once the holes are dug, line the bottoms with gravel for drainage, then pour concrete into the holes. The footing depth in inches divided by eight will tell you how many bags of concrete mix you need.
