Top or Bottom of Footing? - Foundation engineering | Eng-Tips Frost depth always has been and should be to the bottom of the footing You are trying to avoid a condition where frost occurs in the soil directly under a footing and in which case the soil expands (or rather the moisture freezes and expands within the soil matrix) and dislocates the footing
Frost box? - Foundation engineering | Eng-Tips A "Frost box" is probably a term for a variation (enhancement) of the sheet insulation over the pipe, where vertical insulation is placed along the pipe to better protect the pipe contain the heat
Frost Penetration and Movement - Geotechnical engineering general . . . 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
Sources for Frost Depth Values - Structural engineering general . . . Hello all, this is my first post here so please bear with me Where do you go to find accurate frost depth line values? At my job, we often have to design footers foundations rapidly so as to get them to a costumer for the purposes of an estimate Because everything needs done ASAP, contacting
Exterior Large Equipment Pad with deep frost depths - Eng-Tips Frost heave isn't really caused by just the moisture in the soil freezing (and the subsequent small volume increase) It becomes an issue when ice lensing happens This is when a horizontal layer of ice forms and continues to grow in thickness as water is drawn into the freezing layer through capillary action in the soil If you have non-frost susceptible soil (large granular fill), capillary
Frost Heave Calculation - Foundation engineering | Eng-Tips Frost heave can easily be several inches in northern states with frost-susceptible (silty) soils and a shallow water table or just poor drainage On the other hand, dry, clean, sand or gravel may freeze without heaving Heave can vary a lot from year to year depending on moisture conditions and weather

Frost Protection for Interior Footings - Civil Environmental . . . It's the same concept as using horizontally projected insulation as a building apron for shallow frost protected footings That said, you may give consideration to adding insulation or other frost protective measures at the perimeter, where there is a greater chance for frost penetration
How is frost depth determined calculated? - Eng-Tips If frost depth is determined for a county, how many tests do they perform before the county is satisfied with their estimate of frost depth? Is climate change taken into account in frost depth calculations? It seems to me that there are a ton of variables that could affect frost depth, so am just curious how these numbers are typically determined
