Slab lifting with mudjacking, where a cement slurry is pumped beneath an intact panel, has a typical national range of $3 to $6 per square foot lifted. That is a national figure, not a San Antonio rate, and it applies only when an intact concrete slab is compatible with the method; it does not price polyurethane foam lifting, the removal and replacement of fractured panels, drainage construction or broad soil remediation.
Scope and planning guidance
The $3 to $6 per square foot range covers eligible mudjacking work, not arbitrary subgrade reinforcement or replacement. Published figures for polyurethane foam lifting vary too widely to give a dependable range, so foam work is priced from site conditions: the size of the void, the volume of foam needed, the slab area and access for the equipment. Foam usually costs more than mudjacking. Keep the area and method separate from other work items.
A liftable slab is different from a broken slab
The critical price distinction is whether the existing concrete can be reused. An intact slab that has settled as a unit may be a candidate for lifting. A panel broken into unstable pieces cannot simply be made whole by adding material beneath it. The evaluation should check slab thickness, damage, adjoining joints, available injection locations, desired height change and whether there is a meaningful void below the pavement. If the concrete is unsuitable, a leveling price is the wrong benchmark. A replacement estimate should explain demolition, base rebuilding and new concrete instead.
Polyurethane foam and slurry have different inputs
Foam lifting and slurry-based mudjacking differ in injection material, density, hole pattern, equipment, control and return-to-use requirements. One method is not universally better at every property. An estimate should identify which is proposed and why it fits the slab and support conditions. The amount of injected material cannot always be calculated from the visible depression alone, particularly where soil has washed away beneath a large panel. Access to the slab and the risk of disturbing the garage threshold also affect work planning.
Drainage can be the larger cost problem
A driveway panel may drop because bedding has washed out or soil movement has reduced support. Lifting changes elevation but does not automatically change where rainwater travels. If water still runs beneath the panel from a gutter, driveway edge or failed drain outlet, the cause may remain active. A cost comparison should distinguish the lift from any grading, drain or base correction. Combining them may be appropriate when the work is related, but drainage cannot be assumed included in a per-square-foot leveling figure.
Ask what is actually measured
Before accepting the proposal, ask for a description of the low area, intended final elevations, crack limitations, affected joints and how the contractor will verify the new transition is safe for a vehicle. The quote should identify whether injection holes are patched, whether surface cracks are treated separately and whether the slab will regain a workable slope. These questions also reveal why two small lift projects may not cost the same even when their measured square footage is similar.
How public prices fit into a real estimate
A published occupational wage provides context, not a contractor hourly charge. A billed project can also contain supervision, equipment, insurance, disposal, access restrictions and material costs. The BLS-based local wage source describes an occupation, not a universally applicable driveway crew. Never multiply a worker wage by an invented number of labor hours to create a concrete or paving quote. Permit charges also depend on the jurisdiction and should not be mixed into a contractor rate for projects to which they do not apply.
Request a comparable written scope
Share the affected area, surface type, photographs and location through Elm's estimate form. Ask each proposal to state what is included, what is excluded, and how additional work would be approved if concealed conditions are found. An understandable scope is more valuable than a precise-looking number built on missing assumptions.

Questions specific to this cost decision
Can foam injection be quoted without seeing the slab?
A budget discussion is possible, but material quantities and method suitability depend on the slab integrity, amount of settlement, access and the void below. A photograph cannot confirm the hidden support.
If the slab cracked after sinking, is lifting included?
A broken slab may not be eligible for lifting. The estimate should explain whether the intended repair includes lifting, crack treatment, partial replacement or a different solution.
