Q: How deep does a monolithic slab need to be?

• <div><p>The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation&mdash;which are built into a monolithic slab&mdash;sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.</p></div>

Q: How do various elements influence the cost of assembling a unit?
