Foundation Frost Heave

8/4/2009

Foundation system frost heave is a problem that contractors and homeowners encounter in the cold Northern climate on a regular basis. Some of the most common issues usually affect concrete piers supporting decks and/or patios attached  to a residence. These isolated foundations react differently to frost than the conventional shallow foundation systems near the exterior walls of heated residences.

Most contractors will provide the appropriate diameter pier and depth of footing that is necessary to adequately support the vertical loading required by the Code. There are numerous concrete piers in use right now that have performed adequately without any issues. So if a contractor has provided a standard of construction that meets the Code, why are there numerous call-backs, warranty claims, and unhappy homeowners because of heaving pier foundations?
