Foundation repair Georgetown, TX.

A door that suddenly drags on its jamb, a hairline crack walking up from the corner of a window, one room that feels like it tips toward the hallway, in Georgetown these are rarely random. They are the surface signature of ground that does not behave uniformly under a single house, let alone across a neighborhood.

This corner of Williamson County sits where high-plasticity clays drape over fractured Edwards limestone, and the rock beneath does not sit flat. It dips, it fractures, and in places carbonic groundwater has dissolved it into voids. The result is the patch-pattern settlement homeowners here describe as one corner dropping while the rest of the house holds, and the reason a lasting fix has to reach below the clay, not just inside it.

Signs the Georgetown ground is moving your slab

Because bearing is so localized here, the early tells usually show up at one corner or one opening long before the whole house looks off:

• Stair-step cracking in brick veneer near corners or above a door, often the seam between a deep clay pocket and an adjacent zone resting on shallow rock.
• An interior door that latched fine in spring and drags by late summer, after the clay has shrunk through a dry spell.
• Diagonal drywall cracks fanning out from the upper corners of windows and doorframes.
• Gaps opening where the crown molding meets the ceiling, or where trim pulls away from the wall.
• Floors that feel like they slope toward one room, or a slab that simply feels 'off' underfoot.
• Cracks in the slab itself or where the garage floor meets the foundation.

What's actually under your house

The clays sitting on Georgetown's limestone come mostly from the weathering of the carbonate rock itself, with material washed down off the higher terrain to the west. In the deeper pockets their plasticity index commonly runs from PI 30 into the 50s, which means they swell hard when they take on water and pull back sharply through the long Central Texas dry months.

The depth that matters is the active zone, the band of soil where seasonal moisture swing actually drives volume change. In this part of Williamson County that runs roughly six to ten feet below grade. Any pier that stops inside that band is still riding the same shrink-swell forces that racked the foundation to begin with, so reaching below it isn't a preference; it's the whole point.

We drive galvanized steel hydraulic piers through that active clay and on down until the driving resistance confirms a stable, load-bearing horizon, rock, dense limestone rubble, or a consolidated stratum that can actually carry the load. The galvanizing matters here specifically: Georgetown's clays sit saturated for stretches of the year, and an uncoated pier would face corrosion that the coating is designed to outlast. You can see how the method compares on our foundation repair page.
