Unfortunately, there will never be the perfect construction of a foundation that can withstand all changes brought about by weather conditions and home settling. It is this uneven settling or movement that naturally occurs over time that causes most foundation problems. Clay soils naturally expand and contract in the every changing extreme weather conditions and cause foundations to break and need repair. There are other reasons as well which include having a water line or pipe break underneath the home, major flood damage or a long-term drought. Call a professional if you suspect an issue.
