Webb30 apr. 2024 · The soil frost depth was estimated using a soil frost model. Results showed that due to a large variability in the timing of annual maximum wind speed, differences in the 10-year return levels of maximum wind speeds between the frozen and unfrozen soil seasons are generally rather small. Webbfrost will not penetrate below the slab, all footings, including independent column footings, must extend below frost depth, which for footings is 42 inches. Simply thickening the slab in the vicinity of the column in an unheated garage that can go below 32 degrees F will not ensure that frost heave will not occur below the thickened portion.
