Middle Tennessee has a thin layer of clay on top of limestone, and that depth can change quickly across a single lot. Clay moves with moisture, and rock doesn't, so one corner of a house may shift while another stays put. Limestone here can also dissolve and form voids, which is called karst.
Hills matter just as much. Rain runs downhill toward uphill basement walls and builds pressure in the soil. Heavy spring rains are when many block walls show their first crack, and long humid summers keep crawl spaces damp.
Basements and crawl spaces are both common, sometimes in the same house. Our crews stabilize walls, replace crawl space supports and drive piers to rock, which is one thing limestone country does well.
