Get to Know Your Frost

There is a big difference between foundations in areas with significant frosts and those without. The deeper the frost penetration, the more substantial the foundation must be.

When the ground freezes,water retained in the ground also freezes. The expansion of frozen water will exert a force of 150 tons per square inch as it increases in volume by nine percent! This is enough to lift or heave your building, causing damaging strain to many structural elements. You need to build a foundation that will prevent frost from penetrating the soil directly under your building. You will have to design with a specific regard for the soil conditions at your site and for the frost penetration depth in your region — in our part of Ontario, for instance, it's four feet.
