How foam lifting works
Small injection ports are drilled through the settled slab. Structural polyurethane is injected beneath it, where it expands, fills the voids that let the slab drop, and lifts the concrete back toward level. The foam cures in minutes, is engineered to bear load, and does not wash out the way soil does. Compared with tearing out and repouring, foam lifting is faster, cleaner, far less disruptive, and preserves the concrete you already have.
What we lift and level at homes
If the settlement traces to a drainage problem or foundation movement rather than simple soil failure, the evaluation says so, because lifting a slab over an active washout only rents the result.
Foam or mudjacking?
Both lift settled concrete. Foam is lighter, faster-curing, and injects through smaller ports; mudjacking uses a traditional slurry and can be the economical fit for certain slabs. We install both, and the recommendation follows the slab, the soil, and your budget rather than a house preference. See the mudjacking page for the comparison.
Residential work is backed by a transferable workmanship warranty, terms vary by service, with financing available and a written quote within one business day of your evaluation.
Cardinal performs this work across the Dallas-Fort Worth Metroplex and the Houston area.
Frequently asked questions
Typically the same day. Polyurethane reaches working strength in minutes, and most driveways return to vehicle traffic within hours.
Lifting realigns the slab sections and closes many separation gaps, and existing cracks remain part of the slab. Crack repair can be paired with lifting where appearance matters.
The foam itself is stable and does not degrade in soil. Longevity in service depends on the ground beneath it, which is why we identify and address the cause of the settlement, not just the symptom.
Yes, applied correctly, and it is also used beneath foundations themselves as void fill. Injection plans are set by trained crews based on the slab and soil conditions.
