What Causes Floor Cracks?

All concrete in Wisconsin cracks. Basement floors are no exception. Concrete is made of materials that shrink and expand. When concrete meets moisture and changing temperatures, cracking occurs. The problem with basement floors is that because they are poured below the frost line and no expansion joints are required, however, this results in cracking. The older a home is, the more likely it is that cracks will occur. Basement floor cracks are of little concern except if the crack begins to heave and separate and/or it meets up with a basement wall step crack. This could also just be an indication of settlement.
