What would be a consequence of frost heave on a construction site?

Frost heave occurs when moisture in the ground freezes and expands due to low temperatures. This process can push the soil upward, leading to movement of the ground surface. As a consequence, this ground movement can create significant issues on a construction site, potentially damaging foundations, pavements, and other structures. The movement disrupts the stability of the built environment and can lead to uneven settling, cracking of walls, and failure of structural elements.

In contrast, improved foundation stability, increased structural integrity, and enhanced drainage capabilities are not outcomes associated with frost heave. These options imply a strengthening or beneficial effect on the construction, which does not align with the detrimental impact that frost heave has on soil consistency and built structures. The phenomenon primarily poses risks rather than advantages in construction settings.
