How do prairie clay soils affect foundations around Glencoe?

The clay-rich prairie soils common across McLeod County expand when wet and shrink when dry, and that seasonal movement puts real stress on Glencoe foundations. Combined with deep winter frost that can heave footings, these soils are a leading reason we pay close attention to basement walls, slabs, and grading. During an inspection we look for stair-step cracking in block foundations, horizontal cracks or bowing that suggest soil pressure, settlement around additions and porches, and signs of past water intrusion. We also evaluate the grading and downspouts, because keeping water away from the foundation is the single best defense against clay-soil movement. Older homes with stone or early block foundations and rural farmhouses get extra scrutiny here. Not every crack is structural, and part of our job is telling you the difference between normal settling and a problem worth a structural engineer's opinion.
