- Frost box? | 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 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

Hi all, this may be old to someone but i need your input on frost heave design for my foundation I'm designing an unheated structural slab supported on piles Design depth of frost penetration is 2700mm from soil report I'm going to use Dow ethaform void form but i dont know how to calculate

- Which soils are most susceptible to frost heaving? | Eng-Tips
However there is still some potential for frost heave, especially of there are variations in the soil As mentioned in the other thread, would be best to insulate footings having inadequate cover (side of wall below grade and laterally over footing) to maintain soils thawed under footing
