What is the frost line depth?

Answer

The frost line (also called the freezing depth) is the measurement at which groundwater in soil is expected to freeze. The frost line is dependent on several factors: nearby heat sources, climactic conditions of the area and the heat transfer properties of the soil. It is important to know what the frost line depth is in your area before undertaking certain construction projects, as building codes sometimes take frost line depth into consideration because of frost heaving, which can weaken or shift the foundations of buildings. Pipes are also generally installed below the frost line, or insulated to prevent them from freezing.

Any local building inspection department should be able to tell you the frost line depth of your area, so be sure to contact them for this information before undertaking major building projects that may be impacted by freezing groundwater.
