Southern Michigan is no stranger to severe weather that can change daily. That weather can cause multiple freeze thaw cycles causing water in cracks to continuously freeze and then thaw. Expansion of those hairline fractures can grow into much larger problems like weakening the structural integrity of your foundation.
As mentioned above severe weather in Southern Michigan during the winter can sometimes mean extreme swings in temperature. This really wreaks havoc on the soil causing multiple freezing and thawing cycles. When the soil gets wet and is above freezing, water will penetrate deep into the soil and start to expand. Then the temperature begins to dip causing the water in the soil to freeze and expand even more, pushing it's way to the surface causing all sorts of issues for your home and it's foundation.
