Slab Foundation Repair in Keller, TX for Settled and Cracked Slabs
We repair slab foundations on Keller homes. A slab is concrete poured at ground level, so when the soil under one edge drops or swells, the floor above it slopes, doors stop closing and cracks open at the corners of windows and doors.

Most slab repairs begin with a measurement, not a lift. We map the floor, find where the slab moved and by how much, and repair that part. A section that settled gets piers. A void under the slab gets filled. A leak or a drainage fault that moved the soil gets fixed first, or the repair fails again.
What We Do to a Slab Foundation in Keller
We lift and stabilize settled slabs with piers
When the soil under a slab edge has dropped, we set piers under the slab to carry the load on firmer ground, then raise the slab toward level. The Texas Section of the American Society of Civil Engineers says underpinning plans should show the locations, sizes and depths of the underpinning elements, so we mark every pier on the plan before work starts. Foundation leveling and settlement repair
We fill voids and level with slab jacking
Where the slab sits on a void but has not dropped far, we pump grout under it to restore support. The ASCE guidelines state that grouting provides continuous slab support without lifting appreciably, and that mudjacking adjusts elevations hydraulically with continuous uniform support. We say which one fits your slab on the estimate.
We repair the cracks the movement opened
Slab and wall cracks are sealed or injected once the movement is stopped. Foundation crack repair
We fix the water that moved the slab
A broken drain line under the slab and a downspout that empties at the wall both move soil. We test the lines and correct the grading as part of the repair. Foundation leak repair
Work is performed by independent professionals. Every project starts with an inspection and a written price before any work begins.
How We Repair a Slab Foundation
First, we measure floor elevations across the house and mark every crack, sticking door and gap. Second, we check drainage, gutters and downspouts, and test the water supply and drain lines for leaks, which the ASCE guidelines call for when a repair includes jacking or lifting. Third, we write the plan with the pier locations, sizes and depths, and the price. Finally, we do the work, measure the floor again and walk the result with you.
A slab does not come back to perfectly level. The ASCE guidelines state that it is unlikely elevation adjustments will result in a level foundation, so the target is a floor that performs, with doors that close and cracks that stop growing.
Why Keller Slabs Move
The Texas Section of ASCE states that Texas has large areas with clayey soils that shrink and swell with changes in soil moisture. The USDA soil survey for Tarrant County maps mostly fine sandy loams around Keller, with clay soils in patches. USDA describes the Sanger series as 40 to 60 percent clay with high shrink-swell, and describes Crosstell, also mapped around Keller, as a fine sandy loam over a clay subsoil that cracks when dry.
Census Bureau figures (American Community Survey, 2020-2024) show about 89% of Keller's occupied homes are single-family detached houses and about 90% were built in 1980 or later. A slab that has been through decades of wet and dry seasons shows its movement as a crack, a slope or a sticking door. Why Keller soil moves foundations
When a Slab Needs Repair
- A floor slope over 1 percent, about 1 inch across 8 feet, which the ASCE guidelines call usually noticeable
- Diagonal cracks running from the corners of doors and windows
- Doors and windows that stick or will not latch
- A gap between the slab and the wall, or tile that has cracked
- A slab crack that is growing
One hairline crack in concrete is common. The ASCE guidelines state that the majority of cracks do not compromise structural integrity. A crack with a sloping floor beside it is a different case, and we measure to tell them apart.
What Slab Foundation Repair Costs in Keller
A 2026 HomeGuide national guide (published February 6, 2026) puts steel piers at $1,000 to $1,600 per pier, slab jacking at $4,500 to $9,000 or $4 to $9 per square foot, and settling or sinking repair at $4,500 to $20,000. It puts a pier job for a whole foundation at $10,000 to $20,000.
Those are national averages, not Keller quotes. The number of piers, how far the slab dropped, access around the house and any leak or drainage repair set the price for a specific house. What foundation repair costs in Keller
Frequently Asked Questions
What causes a slab foundation to settle in Keller?
Soil movement under the slab. Clay that shrinks in dry weather and swells when it rains, a leaking drain line under the slab, and a downspout that dumps beside the wall all move the soil. The USDA maps mostly sandy loams around Keller with clay patches, so the cause differs from lot to lot. We trace the cause on the inspection and fix it with the slab.
Do I need piers, or is slab jacking enough?
Piers carry the slab on firmer ground and raise it. Slab jacking fills a void and restores support without lifting far. Piers fit a slab that dropped, and jacking fits a slab sitting on a void. The ASCE guidelines state grouting provides support without lifting appreciably. We measure the slab and the settlement, then say which one the house needs.
How much does slab foundation repair cost in Keller?
HomeGuide's 2026 national guide puts steel piers at $1,000 to $1,600 each and settling or sinking repair at $4,500 to $20,000. Those are national averages, not Keller quotes. The number of piers, the depth of the movement and what is found under the slab set the price, and an on-site inspection gives the real number.
Will repair make my slab perfectly level?
No. The ASCE guidelines state that it is unlikely elevation adjustments will result in a level foundation. The goal is a slab that performs, with floors that stop sloping, doors that close and cracks that stop growing. We measure the floor before and after the repair and show you both sets of numbers.
Do I need an engineer before slab repair?
For a small repair, an inspection can be enough. For a large or disputed repair, an engineer's report gives an independent measurement and a repair plan. In HomeGuide's national guide, a structural engineer's report costs $500 to $3,000. Foundation engineer's reports in Keller
