This process … WebMar 1, 2024 · What is frost heave? Frost heave is a phenomenon whereby frozen soil adheres to a foundation element, like a pile, and imparts upward pressure on the foundation when it expands. If the foundation element is unable to resist the upward pressure, it displaces with the soil. When the soil thaws, it may return to its original position.
