Foundation repair in Cedar Park, on the metro's western transition zone.

Most of the city's stock is 1990s–2010s slab construction now deep enough into its clay cycles for patterns to emerge. We measure both sides of the seam on the same free terms.

AREAS WE SERVE IN CEDAR PARK: BUTTERCUP CREEK AND WESTSIDE PRESERVE, TWIN CREEKS, RANCH AT BRUSHY CREEK, CYPRESS MILL, BELLA VISTA, AND ANDERSON MILL TOWARD THE BRUSHY CREEK LINE — THE NORTHWEST ANCHOR OF OUR AUSTIN RUN.

The ground under Williamson County

Cedar Park sits right on the Balcones Escarpment — where limestone hands off to clay.

Cedar Park straddles the Williamson–Travis county line about twenty miles northwest of downtown Austin, and it sits directly on the Balcones Escarpment: the long fault-line arc where the Edwards Plateau's limestone hills to the west drop away to the Blackland Prairie's clay flats to the east. Along that break, Lower Cretaceous limestones are literally juxtaposed against younger claystones and marls — so a city can carry two soils at once. The USDA maps the Georgetown series as the dominant ground here, a clayey soil with real shrink-swell potential, and that's exactly what shows up on the east side toward U.S. 183 and Bell Boulevard: houses that cycle with the rain gauge the way Round Rock's do.

But push west toward the lake side and Buttercup Creek and the soil thins over rock fast. There the story flips: minimal shrink-swell, but cut-and-fill pads on gentle grades that settle where placed fill meets native limestone, and drainage that has to be managed on sloping lots. The lots that give us the sharpest readings are the straddle lots caught in between — one end anchored on rock, the other on a clay seam — because every seasonal swing concentrates at the clay end while the far side stays put. That single fact is why the elevation survey matters so much here: a glance at a crack tells you nothing about which of Cedar Park's two grounds your house is actually living on.

The housing stock

1990s–2010s slab subdivisions now deep enough into their clay cycles to talk.

Cedar Park's population roughly quadrupled between the mid-1990s and today, and its housing waves track that boom: dense 1990s and 2000s slab-on-grade subdivisions filling in first, then the 2010s master-planned communities. That timing matters — the earliest of those slabs are now fifteen to thirty years into their wet-dry cycles, squarely in the window when first-time perimeter movement shows up on the clay side. Buttercup Creek, Carriage Hills, and the Anderson Mill edge carry much of that older stock; Ranch at Brushy Creek and Twin Creeks brought the larger, later footprints.

The repair mix follows the ground, not a slogan. East-side clay homes get the corridor's classic scope — perimeter piers carried to steadier ground when doors rack and brick steps after a hard summer. Lake-side and west-side homes on fill get the Hill Country scope — drainage correction, gutters, and targeted fill-side support far more often than long pier runs. On a Cedar Park straddle lot we frequently do a little of both, guided entirely by where the elevation map says the fill, the rock, and the clay seam actually sit.
