Cast stone with freeze-thaw damage
Freeze-thaw damage in cast stone occurs when absorbed water fills its pores, freezes, and expands by roughly 9%, causing internal pressure, cracking, and surface spalling. This cyclical, slow-acting deterioration is worsened by high porosity, moisture saturation, and deicing salts.
