Frost Action

Frost action refers to the phenomenon that occurs when water within soil or porous materials freezes and expands. During cold weather, liquid water seeps into tiny spaces or cracks. As temperatures drop, this water freezes, causing it to expand. This expansion can exert pressure, leading to cracking or weakening of the material, such as roads, buildings, or stone structures. When the ice thaws, the material may not fully recover, leading to further damage over time. This process is particularly significant in construction and road maintenance, where understanding it can help prevent structural failures.
