The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 °F). Alternatively, in Arctic and Antarctic locations the freezing depth is so deep that it becomes year-round permafrost , and the term " thaw depth " is used instead.
In construction, the thaw depth is a major factor in ensuring the structural integrity of the objects in question. The primary factor that determines the thaw depth is the maximal air temperature. The soil type is another important factor: coarser textures of the parent material have higher thermal conductivity , and, e.g., sandy soils have ...
