Foundation Repair in Georgetown, TX Built for Clay, Limestone and Drought

When the soil under a slab gains or loses moisture unevenly, the edges rise or drop relative to the center. Clay at the perimeter dries out and shrinks in drought, then swells after heavy rain. That cycle bends the slab and cracks everything built on top of it.

The Houston Black and Branyon clays east of I-35 rank among the most expansive soils in Texas. During the 2011 and 2022–2023 droughts, perimeter soil dried several feet deep. Then spring storms re-wetted it unevenly. Water restrictions cut yard watering just when slab edges needed moisture most. Big live oaks and cedar elms pull even more water out in summer. Repeat that for a few years and the perimeter beams either sink or ride up while the interior stays put.

• Stair-step cracks in brick or stone veneer
• Doors that stick or won't latch
• Gaps between window frames and brick
• Floors sloping toward one side of the house
• Diagonal drywall cracks at door and window corners
• Cracked floor tile running across a room

We see this most in Weir, Hutto, Taylor and east Round Rock on Blackland clay. It also shows up in Wolf Ranch and Georgetown Village homes that are going through their first big drought-and-rain cycle. Corners near mature trees usually move first.

Our fix: Pressed pilings or drilled concrete piers set below the active clay zone, careful lifting, then drainage and moisture control so the problem doesn't come back.

Part of the foundation rests on or near rock, and the rest sits on clay or fill dirt. The rock end stays put and the clay end moves. That pulls the house in two directions and concentrates cracking along a line across the structure.

West of I-35, karst limestone can sit only a few feet down on one side of a lot and drop away on the other. Many hillside subdivisions were built on cut-and-fill pads, so the uphill half of a slab sits on cut rock and the downhill half sits on compacted fill. Between the two zones, shallow clay over chalk is common. Fill can consolidate, and clay keeps swelling and shrinking while the rock end stays still. Piers have to be planned around where rock actually is.

• One crack line running across the whole house
• Cracks in the garage slab continuing into the house
• Floors that dip toward the downhill side
• Separation where the patio or porch meets the house
• Interior doors out of square on only one end of the house

Common in Berry Creek, Serenada, Cimarron Hills, the Lake Georgetown area, Leander and Liberty Hill. On these lots, piers may hit refusal on shelf rock at shallow depth, so the equipment has to handle rock.

Our fix: Pier placement planned from soil and rock conditions, with drilled piers where pressed piling would stall early, plus leveling across the transition zone.

Water or sewage leaking under the slab soaks the soil in one area. That clay swells and lifts the slab, or the soil washes out and leaves a void. In both cases one section of the house moves and the rest doesn't.

The 1970s–80s homes in Round Rock, Brushy Creek, Wells Branch and Jollyville have cast-iron drains that are now 40–50 years old and corroding. Winter Storm Uri in February 2021 burst pipes all over the area, and some of those leaks went unnoticed under slabs. Leaks can also mask heaving, because the wet spot rises while the dry perimeter sinks, and that misleads anyone who only takes floor elevations. That's why we recommend a plumbing test alongside the foundation evaluation whenever the pattern points to a leak.

• Unexplained jump in the water bill
• Warm or damp spots on the floor
• Mildew smell or lifting flooring
• Slow drains or recurring sewer backups
• A hump or crack concentrated in one room
• Sound of running water with fixtures off

Most common in 40–50-year-old slabs in Brushy Creek, Wells Branch, Forest Creek and Jollyville. We also find it in newer homes after freeze events. Kitchens, baths and laundry areas are the usual locations.

Our fix: Coordinated plumbing leak testing, repair of the leak by a licensed plumber, then slab leveling or void correction once the soil stabilizes.

Older raised homes sit on wood, stone or concrete piers that support beams and floor joists. Over a century, wood piers rot, masonry piers settle or tilt, shims crush, and sills and girders sag. You end up with bouncy, wavy floors.

Old Town Georgetown and the streets around the Downtown Square are full of homes built before slabs were the norm. Many crawl spaces are poorly vented and stay damp after Flash Flood Alley storms, which speeds up wood rot. The clay under them still swells and shrinks, so individual piers move at different rates. Any visible exterior change in the historic overlay can also trigger design review, so repairs need to preserve original materials where possible.

• Soft, bouncy or sagging floors
• Floors sloping toward the center of the house
• Gaps under baseboards
• Damp, musty crawl space
• Cracked plaster at ceilings
• Doors swinging open or closed on their own

Typical in Old Town Georgetown, near Southwestern University, in Downtown Taylor and in older homes in Granger, Florence and Round Rock's original town. Most are Victorian, Queen Anne and early-1900s cottages.

Our fix: Replace failed piers with concrete, sister or replace damaged sills and girders, re-shim to level, and improve crawl space ventilation while keeping historic finishes intact.

Water that collects against the foundation saturates the perimeter clay, so it swells, softens or washes out. Flat or reversed grading, short downspouts and clogged gutters are the usual culprits. Drainage problems often cause foundation damage in the first place.

Storms here often drop several inches in a few hours after weeks of dry weather, and the bad grading shows up all at once. Hilly subdivisions send runoff from uphill lots into downhill yards. Homes near the San Gabriel River forks and Brushy Creek deal with high runoff. Builder grading on cut-and-fill pads often settles flat within a few years. Landscaping beds and flatwork added later frequently trap water against the slab.

• Standing water near the foundation after rain
• Downspouts dumping right at the slab
• Soil eroded away from the slab edge
• Mulch beds sitting higher than the slab
• Water stains on interior baseboards along one wall

Very common in hillside lots in Berry Creek, Teravista and Cimarron Hills and in Sun City homes with heavy landscaping. Flat Blackland lots in Hutto and Pflugerville often pond water too.

Our fix: Regrading, French drains, downspout extensions or underground lines, and surface drains, with HOA architectural approval handled where required.

Post-tensioned slabs use steel cables under very high tension to hold the concrete in compression. They resist cracking well but can still deflect on moving clay. Drilling into a cable carelessly is dangerous and can weaken the slab.

Most homes built here since the mid-1990s, including Sun City Texas, Wolf Ranch, Teravista and the newer subdivisions in Leander, Liberty Hill, Hutto and Jarrell, sit on post-tensioned slabs. Many 2000s–2010s homes are now outlasting their builder warranties just as the soil goes through its first serious drought-and-rain cycles. Veneer, tile and drywall show the movement quickly. Repairs have to follow Post-Tensioning Institute practices and stay clear of tendons.

• Hairline-to-wide cracks in stone or stucco veneer
• Tile cracks in long straight lines
• Garage door that no longer seals evenly
• Cracks above interior doorways
• Exposed cable ends or rust staining at the slab edge

We see this mostly in Sun City Texas, Wolf Ranch, Teravista and Georgetown Village, and in builder homes in Hutto and Leander that are 8–20 years old.

Our fix: Cable-aware pier placement and leveling, repair of any exposed or damaged tendon ends, and drainage improvements to limit future movement.

Thin shrinkage cracks in slabs, garage floors and driveways are common and often cosmetic. They still let moisture and soil gases in, and they can be early signs of bigger movement, so they're worth recording and watching.

Concrete shrinks as it cures, and Central Texas heat speeds that up. Cracks often open during drought and close after rain, so many homeowners wait. A crack that's under about 1/8 inch and isn't moving is usually just a sealing job. A crack that widens, offsets or keeps coming back is a different story.

• Hairline cracks in garage or driveway concrete
• Cracks under 1/8 inch with no offset
• Cracks that open in summer and close in winter
• Minor spalling at slab edges

Found in nearly every neighborhood, especially garage slabs and driveways in newer subdivisions. Expect them in Jarrell and Liberty Hill builder homes poured in summer heat.

Our fix: Measure and photograph the crack, seal or patch it with epoxy or polyurethane, and check it again after the next season to confirm it's stable.
