The Balcones fault line runs across the top of San Antonio, and it more or less divides the foundation problems in this city. North and west of it the ground turns to Edwards limestone and caliche, often close to the surface, with clay filling the low pockets between. South and east of it there is deep expansive clay that swells after a wet week and shrinks back through a dry August.
Housing age matters just as much. The 1920s to 1960s homes in the older inner neighborhoods are frequently pier and beam, sometimes with a slab addition attached later. Almost everything built from the 1970s onward is slab-on-grade, and the newest subdivisions north of the city sit on engineered pads cut into hillsides. Each of those responds differently to the same weather.
