How many inch wider the bottom frost free fill than the footing?
(OP)
Hi, everybody'
I have a simple question to ask:
To prevent frost heave, the contractor is digging a wide trench to back fill frost free material, my question is how many inches (feet) wider do you usually specify for the frost free fill (or the trench) than the supported footing?
Thanks.

Our frost penetrates about five feet next to a heated building, six to eight feet in open terrain.
