As winter fades away, its lasting impact can be seen underground, causing potential issues. Frost heave occurs when frozen ground thaws unevenly, leading to soil shifting, expanding, and sometimes rising upward. This occurs due to water in the ground freezing and expanding during cold weather, then contracting as it thaws. Over time, this cycle can damage roads, sidewalks, and building foundations, resulting in cracks in concrete and uneven surfaces.
In late winter and early spring, frost heave becomes more prominent as temperatures rise and thaw the frozen ground from the surface downward. This not only affects pavement but also concerns farmers, as it can harm plant roots and disrupt early spring planting. Frost heave is a natural force that continues to shape the landscape long after winter has passed.
