Concrete lifting
Concrete Lifting and Void Filling in Houston, TX
Gulf Coast clay moves. Polyurethane foam injected under a settled slab lifts it back into place.
Free on-site assessment across Greater Houston. A written scope before anything is ordered.
The work
Lifting a slab back into place
Houston sits on expansive clay that swells when wet and shrinks as it dries. Slabs poured on it move, and when the soil underneath pulls away, the concrete is left bridging a void until it settles into it. It comes up most often out along the SH-288 corridor, where the clay is at its most active.
Concrete lifting corrects that in place. Small holes are drilled through the slab, expanding polyurethane foam is injected underneath, and the expansion fills the void and raises the slab back toward level. The holes are patched and the area is usable the same day.
It is the right answer for a settled slab over a void. Structural foundation work, and slabs cracked clean through, belong to a different trade. If that is what we find, we will tell you and point you at the right trade instead. Where the visit is also about the envelope, the insulation scope is written separately so you can see both numbers.
Is this you?
What we lift
Driveways and approaches
Where the settlement is at the joint and the trip hazard is at the edge.
Patios, walkways and pool decks
Common on fill that was placed loose.
Warehouse and shop floors
Including under racking, where a void becomes a load problem.
On the written scope
How the job works
- Written scope and price Per area, before we drill anything.
- Void assessment We establish what is under it before deciding it can be lifted.
- Injection through small ports Drilled, injected, then patched.
- Lift monitored as it happens Controlled in stages, a lift at a time.
- Usable the same day In most cases, within hours.
- Clean-up and patching Holes filled and the area left tidy.
How it runs
One process, three stages
Most residential slabs are a few hours.
-
1
Inspect
We look at the slab: where it has moved, how much, and what is likely underneath.
-
2
Scope
The scope and the price by area, in writing, before we drill anything.
-
3
Install and verify
Small ports drilled, foam injected in controlled stages, then patched and checked for level, and we walk it with you before we leave.
Questions
Asked about this service
Same idea, different material. Mudjacking pumps a cement slurry; this uses expanding polyurethane, which is far lighter, needs smaller holes and keeps the load off the soil that just failed under the slab.
Usually the same day, often within a couple of hours. The scope will give you the figure for your job.
The foam stays put and holds its volume. Whether the ground moves again depends on the ground — if there is a drainage problem feeding the movement, fixing the drainage is part of the answer and we will tell you if we see one.
This is slab and flatwork lifting. Structural foundation repair is a different trade, and we will point you toward someone who does it.
The visit is free. Someone comes out, looks at the building and gives you a written scope and a price, and the decision stays yours.
We work across 48 cities in the eight-county Houston–Galveston area — Harris, Fort Bend, Montgomery, Brazoria, Galveston, Chambers, Liberty and Waller — plus a set of extended project markets beyond it. If you are near the edge of that, call and ask.
It depends on the size of the slab, how far it has dropped, how much empty space is under it and the number of injection points it needs. We measure all of that on site and put the price in writing before any work starts.
Yes. Where the slab is still where it should be but the soil under it has washed out or pulled away, we fill the void with polyurethane foam so the concrete is supported again.
Yes. Driveways and approaches, patios, walkways and pool decks are all work we do. We lift the slab in place with polyurethane foam rather than tearing it out.
Foam jacking, also called polyjacking, lifts a sunken slab by injecting expanding polyurethane foam under it through small holes. It is how we lift concrete. Mudjacking does the same job with a cement slurry.
