False, there are soils that are none frost susceptible (NFS) like dry gravel that don't heave.
In some soils a footing to the frost line isnt sufficient to prevent frost jacking. Where the freezing soil heaving lifts the footer out of the ground with friction along the sides instead of from heaving underneath.
