TL;DR
A frost depth footing is a foundation element deliberately carried below the local frost line so the bearing soil beneath it never freezes, immunizing the structure against seasonal heave. Concrete contractors form them for stoops, slab thickened edges, and attached structures whose movement would crack the connection to the house.
What it means
A frost depth footing is a foundation element deliberately carried below the local frost line so the bearing soil beneath it never freezes, immunizing the structure against seasonal heave. Concrete contractors form them for stoops, slab thickened edges, and attached structures whose movement would crack the connection to the house. The IRC mandates frost protection for most permanent foundations, achieved by depth, by insulated shallow-footing designs, or by bearing on rock — depth being the default that inspectors verify in the open trench.
