Freeze-Thaw Cycle Concrete Damage

New Jersey winters subject concrete slabs to repeated freeze-thaw cycles that cause significant movement. Water beneath or within the slab expands when it freezes, pushing sections upward, then contracts during thaw, leaving gaps and uneven panels. Over multiple seasons this produces significant height differentials, joint separation, and surface cracking. Concrete leveling lifts depressed sections and fills the subsurface voids left by frost action, stabilizing the slab against future heave cycles.
