WebOct 25, 2009 · Frost penetration and frost depth effects are really two different animals. As OldestGuy indicated, even in very cold climates, they recognize that footings do not have to go full depth of frost penetration if they are in non-frost susceptible soil. If the soil is non-frost susceptible (meaning that there is no significant change in volume (i.e ... WebNRCC Research Publication RR 96-1. Extreme values of the maximum depth of soil freezing are of interest for engineering design specifications. For instance, building codes must consider the maximum depth of frost penetration to assure that footings and utilities are buried at the appropriate depths. If these specifications are too lax, freezing ...
