How does Minnesota's freeze-thaw cycle affect a home's foundation?

Minnesota's brutal freeze-thaw swings put real stress on foundations, and Coon Rapids homes are no exception. Water that gets into soil and small concrete cracks expands as it freezes, then contracts as it thaws, and after enough winters this works cracks wider, heaves slabs and stoops, and can shift foundation walls. Our sandy Anoka Sand Plain soils drain well, which helps, but poor grading, disconnected downspouts, or a failing sump can still concentrate water against the foundation and accelerate damage. During an inspection we look for the signs: stair-step cracks in block walls, horizontal cracks that suggest lateral pressure, bowing or leaning walls, heaved garage and entry slabs, separating stoops, and moisture or efflorescence indicating water is getting in. Most foundation cracks are minor and cosmetic, but some signal movement that needs a structural engineer's eye, and we'll tell you which is which rather than alarm you unnecessarily. The best defense for any homeowner is keeping water away from the foundation.
