What can be lifted rather than replaced
- Driveway and garage apron sections that have dropped at the joint.
- Sidewalks and walkways that have become trip hazards - often a liability issue as much as a cosmetic one.
- Patio slabs, porch slabs and pool decking.
- Steps that have separated from the house or settled unevenly.
- Concrete that has sunk but is otherwise sound. Badly spalled or crumbling concrete is a replacement, not a lift.
Foam versus mudjacking
- Polyurethane foam is injected through small holes, expands, and lifts. It is light, cures in minutes, and the holes are small.
- Mudjacking pumps a cement slurry underneath. It costs less per job in many cases but is heavier and uses larger holes.
- Foam's low weight matters on soft or previously washed-out soil, where adding weight can restart the settling.
- Neither fixes the reason it sank. If water is washing soil out from beneath the slab, that has to be dealt with or it will settle again.

Why we won't quote you a number
Leveling is priced by how much slab has to move, how far it has to move, and what is underneath it. The wildcard is the void - nobody knows exactly how much material a slab will take until they start filling it.
What a contractor is actually pricing
| Factor | Why it moves the number |
|---|---|
| Area to be lifted | Square footage of affected slab is the starting point. |
| How far it has dropped | A greater lift means more material and more time. |
| Void size beneath | If soil has washed out, the cavity can take far more material than the surface suggests. Ask how this is handled in the price. |
| Method | Polyurethane foam is light, fast and uses small holes. Mudjacking uses a cement slurry, larger holes, and adds weight - which matters on soil that has already washed out. |
| Access | A back patio reached through a narrow gate is slower than a driveway the rig can park beside. |
| Slab condition | Sound concrete lifts well. Concrete cracked into many pieces or crumbling is a replacement conversation. |
| Cause of the settling | If water is washing soil out, that has to be addressed or it settles again - and that is drainage scope, not leveling scope. |
| Finish expectations | Joints, edges and visible patching all take extra care on a prominent front walk. |
How to compare bids fairly
- Be clear this is flatwork - driveway, patio, walkway, garage slab - and not your house foundation. Different work, different warranty, and sometimes a different contractor entirely.
- Compare the method. Polyurethane foam injection is light, cures in minutes and uses small holes; traditional mudjacking uses a heavier slurry and larger holes. They suit different slabs and soils.
- Confirm the void underneath is being filled, not just the slab lifted. Lifting over an unfilled void settles again.
- Ask why it settled. Washout from a downspout, poor compaction over a backfilled trench, erosion or a plumbing leak - if the cause is not addressed, it repeats.
- Compare hole count, hole diameter and how the patches are finished. They stay visible, and how visible varies by method.
- Ask whether any section is too broken to lift and would be better replaced. Lifting a failed slab is money spent twice.
Questions to ask every contractor
- Foam or slurry, and why is that the right choice for this slab?
- Are you filling the void underneath, or only lifting the slab?
- Why did this settle in the first place, and is that cause being addressed?
- How many holes, what diameter, and what will the patches look like when you are finished?
- Is any section too broken to lift? Would replacing it be better value?
- Could lifting this slab affect the house foundation or anything plumbed underneath?
- Does the warranty cover re-settlement, or only workmanship?
- Is the downspout or irrigation that caused this part of the fix?

Concrete Leveling — Questions Round Rock Homeowners Ask
Is leveling cheaper than replacing the concrete?
Usually meaningfully cheaper, and much faster - most jobs are done in a day and usable almost immediately. The exception is concrete that is cracked into many pieces or crumbling, where lifting a failing slab just buys a little time.
How long does concrete leveling last?
If the cause of the settling is addressed, a long time. If water is still washing soil out from under the slab, it will settle again - which is why a good contractor asks where the water is going before quoting the lift.
Does a sunken driveway mean my house foundation is moving?
Not necessarily. Flatwork like driveways and walkways sits on shallow soil with far less support than a house foundation, so it moves much more readily. It is worth having someone look at the house, but a sunken sidewalk on its own is not evidence of a structural problem.
Will you see the holes afterward?
Foam injection holes are small and are patched, though on a visible surface you may still make them out on close inspection. Mudjacking holes are larger. Ask to see photographs of finished work before you choose a method.
Can concrete leveling fix my pool deck?
Often yes, and it is a common application. Settled pool decking is usually a drainage story, so expect a good contractor to look at where the water goes before quoting.
Is leveling cheaper than replacing?
Usually meaningfully cheaper and much faster - most jobs finish in a day and are usable almost immediately. Badly broken concrete is the exception.
Foam or mudjacking - which should I choose?
Foam for speed, small holes and light weight on soft soil. Mudjacking is often less expensive where weight is not a concern. A contractor who explains the trade-off rather than only selling one is a good sign.
Will it sink again?
Not if the cause is dealt with. If water is still washing soil from beneath the slab, any lift is temporary - which is why a good contractor asks about drainage before quoting.
Does a sunken driveway mean my house is moving?
Not necessarily. Flatwork sits on far shallower support than a house foundation and moves much more readily. Worth having the house looked at, but not evidence on its own.
Can settled pool decking be lifted?
Often yes, and it is a common job. It is usually a drainage story underneath, so expect that to come up.
