- Frost Heave Calculation | 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 of fill | Eng-Tips
The depth the frost will penetrate below the insulating layer depends on insulating value (thermal conductivity and thickness), initial ground temperature, and of course the air temperature over the freezing period
