About South Austin
Funky South Austin, where Barton Springs limestone gives way to clay toward Onion Creek.
Why foundations move here
Like the rest of Austin, South Austin sits on ground that shifts with the seasons. Notorious 'Austin clay' east of MoPac; thin soils over limestone to the west. Steel piers bypass that movement by reaching load-bearing strata below.
Common signs in South Austin homes
- Doors and windows that stick, drag, or won’t latch
- Stair-step cracks in exterior brick or block
- Sloping or bouncy floors and a slab that feels “off”
- Drywall cracks fanning from door and window corners
- Gaps opening between walls, trim, and the ceiling
- Cracks in the slab or at the garage floor
