Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).

Cold Joints

Cold joints are the result of pouring a foundation at two separate times. If part of the foundation is poured and starts to cure, when the second part is poured the visible joint between the two is a cold joint or cold pour.
