Round Rock sits right on the line between Hill Country limestone and Blackland Prairie clay, so two homes a few miles apart can have very different foundation problems.
Round Rock grew up along the Balcones Escarpment in Williamson County, where Brushy Creek crosses I-35. Much of the city west of I-35 sits on shallow soil over limestone. To the east, neighborhoods sit on deeper, dark Blackland Prairie clay that swells after rain and shrinks in summer. Many subdivisions on both sides were built quickly as the area grew, often with cut-and-fill grading.

Many hillside lots include fill soil that can compress over time. If part of the slab is on rock and part is on fill, the fill side can settle and crack the house.
Yes. Runoff that collects on the uphill side, or soaks under one part of the slab, can keep the soil uneven. Grading and gutters are often part of the conversation. See drainage and moisture control.
