Foundation repair · Round Rock, TX
Foundation repair in Round Rock's expansive clay — measured, not guessed.
Round Rock sits squarely on the Taylor and Blackland clay formations — soils that geologists literally classify as 'very high shrink-swell.' Nearly every neighborhood here, from 1980s Round Rock West to the newest sections off University Boulevard, lives on ground that breathes with the weather.
The good news: builders here have engineered for it for decades, and most slabs perform. The pattern we repair is specific — perimeter edges that dry out faster than the protected center, settling a corner after each drought until doors rack and brick stair-steps.

Straight from the soil survey
The USDA maps the dominant soil under Round Rock as Georgetown — high shrink–swell (linear extensibility ≈ 7.4%). It’s clay that moves clearly with the wet–dry cycle, enough to crack brick and rack doors over a few dry summers.

The local patterns, specifically.
Corner settlement after drought summers
The Taylor-clay classic: a southwest or west-facing corner (most sun, most evaporation) drops first. The crack cluster radiates from that corner.
Seasonal door roulette
Doors that stick every August and free up every winter are tracking soil moisture. One-directional worsening year over year is what separates 'monitor' from 'repair.'
1980s–90s slabs aging into movement
Round Rock West and older Brushy Creek sections have 30–40-year-old slabs built to earlier standards — more sensitive to the clay than post-2000 engineered pads.
Flatwork lying to you
Driveways and sidewalks crack readily in this clay and often mean nothing for the house. We measure the slab, not the sidewalk, before concluding anything — though if that cracked flatwork bothers you, we pour and replace driveways, walks and patios as a job of its own.
