Frost heaving (or a frost heave) results from ice forming beneath the surface of soil during freezing conditions in the atmosphere.

The ice grows in the direction of heat loss (vertically toward the surface) starting at the freezing front or boundary in the soil, it requires a water supply to keep feeding the ice crystal growth, and the growing ice is restrained by overlying soil, which applies a load that limits its vertical growth and promotes the formation of a lens-shaped area of ice within the soil.
