Frost Line Map for the United States. The type of soil plays a significant role in the likelihood and severity of frost heave. Soils with high clay and silt content retain more water and are more susceptible to heaving. Sandy and gravelly soils, on the other hand, drain water more effectively and are less prone to frost heave.Frost Line. The frost line is how deep the ground freezes on average each year in a geographic area. In severe winters the frost depth will go deeper than in warmer winters, so the frost line is typically an average. If a deck footing isn’t below the frost line, the freeze-thaw action can cause it to lift, tip, drop, or move laterally.Sep 25. Sep 27. Sep 30. Oct 2. Oct 4. Oct 7. Oct 11.
