Slab Foundation Repair in Abilene
Many Abilene homes sit on a concrete slab poured straight onto clay. When the clay underneath shrinks in a dry summer and swells after heavy rain, parts of the slab move at different rates. The result is cracks, sloping floors and doors that stop closing. Repair means supporting the low sections from below, then lifting them back toward level.
Signs you may need slab foundation repair
One sign on its own can be normal. Two or more, especially near the same corner of the house, are worth a survey.
What a lift changes
Readings taken in a line across the house, from the low front corner to the back. Switch between the survey before work and the re-measure after.

Three ways to fix it
The survey and the soil decide which one fits your house. A good contractor explains why they picked it.
| Method | How it works | Usually chosen when |
|---|---|---|
| M-1Steel push piers | Steel pipe sections are driven down under the slab edge using the weight of the house until they reach firm bearing, then the slab is lifted on them. | The house is heavy enough to drive the piers and firm soil or rock sits deeper down. |
| M-2Pressed concrete pilings | Short concrete cylinders are pressed down one on top of another with a hydraulic jack, then capped and shimmed to lift the slab. | A common choice for slab homes on Texas clay, where bearing soil is not too deep. |
| M-3Helical piers | Steel shafts with screw-like plates are turned into the ground and torqued to a measured resistance before carrying the load. | Lighter structures, additions or porches, or where push piers would not get enough resistance. |
How the work is done
Nothing is dug or lifted until you have the readings and a written plan in hand.
- 01Elevation survey to map where the slab has movedReadings across every room and around the outside show where the slab sits high and where it sits low.
- 02Repair plan based on the survey and soil conditionsPier locations marked on a floor plan, the method chosen, and a written price before any work starts.
- 03Piers installed under the affected sectionsSmall holes are dug next to the low areas, usually along the outside walls, and piers go down until they reach firm bearing below the active clay.
- 04Slab lifted toward level as far as the structure safely allowsJacks raise the slab gradually while doors, walls and tile are watched for stress.
- 05Final elevation readings and drainage recommendationsA second survey records the result, the holes are backfilled and compacted, and you get advice on keeping the soil around the slab steady.
What does it cost?
National averages for foundation repair from Angi's cost guide, not Abilene prices. Your number comes from the survey and a written quote.
- +Number of piers. Set by how much of the foundation has dropped.
- +Depth to firm soil. Deeper bearing means longer piers.
- +Access. Patios, driveways or landscaping in the way add work.
- +Interior work. Needed when the low area is in the middle of the house.
- +Plumbing tests. Often recommended before and after a lift.

The elevation survey is free, and you keep the readings whatever you decide.
Slab Foundation Repair: questions
Will lifting the slab crack my walls or tile?
Some cosmetic cracks can open or close during a lift. A careful, gradual lift reduces this, and a good plan says what to expect beforehand.
Can my slab go back to perfectly level?
Usually not, and it should not be forced. The goal is to bring it back within a practical tolerance without damaging the structure.
Do I need to leave the house during repair?
Most families stay home. Work happens mainly outside, with some noise and digging near the walls.
How do I keep it from moving again?
Piers stop the supported sections from sinking. Good drainage and steady soil moisture help the rest of the slab stay put.
How long does slab foundation repair take?
It depends on the house. Jobs with piers only along the outside walls are the quickest. Interior piers, deep bearing soil, plumbing tests and permit inspections all add time, so ask for an estimate in the written plan.
What happens inside the house during the work?
If every pier goes along the outside walls, not much. You'll hear the work, and you may see cracks close or doors start to latch again as the slab rises. Interior piers mean opening the floor in a few spots and patching it afterward. Take fragile items off shelves on walls near the lift.
Steel or pressed concrete piers: which is better?
Neither is right for every house. Pressed concrete pilings are a common choice on Texas clay where firm soil isn't too deep, while steel push piers can be driven further down. The survey, the soil and the weight of the house decide, and the contractor should explain the choice.
Do I need a plumbing test before a slab lift?
It's often recommended. A pressure test on the drain lines under the slab shows whether they leak before the lift and again after it. A hidden leak can also be what made the clay move in the first place.
Does slab repair in Abilene need a permit?
Inside city limits, generally yes. The City of Abilene's Building Inspections FAQ says a permit is required to repair, alter or move a building. Ask your contractor who pulls the permit before work starts. Outside the city, check with the town or county.
