A sunken or uneven driveway slab can be raised back to level in place — no jackhammering, no full tear-out, and no days of waiting for a new pour to cure.
Driveway settling is usually gradual, and these are the earliest, clearest signs to watch for:
Where two driveway sections meet, one has dropped relative to the other, creating a trip hazard and a jarring bump for cars.
A settled section creates a low spot that collects rainwater or irrigation runoff instead of shedding it toward the street.
As one side of a slab settles faster than the rest, stress cracks often appear along the transition — a sign the slab is actively moving.
If a car noticeably dips or rocks crossing a specific spot on the driveway, that section has likely settled below its neighbors.
Lifting an existing slab back to level is typically far less expensive than demolition, haul-off, and a full new pour — often for a comparable end result.
Most driveway lifting jobs are completed and drivable again the same day, versus the days of cure time a fresh pour requires before it can bear weight.
Because the existing slab stays in place, surrounding landscaping, sprinkler lines, and edging are left alone — a full replacement often disturbs all three.
Most contractors matched through this network use polyurethane foam injection: a series of small (roughly dime-sized) holes are drilled through the slab at strategic points, and a dense, expanding structural foam is injected beneath the concrete. As the foam expands, it fills the void left by washed-out or compacted soil and gently raises the slab back toward level.
Older mudjacking methods use a heavier cement-based slurry instead of foam — it can work, but the added weight sometimes contributes to future settling on soil that was already struggling to support the slab. Foam is lightweight, cures in minutes rather than days, and the small injection holes are far less visible than the trenches traditional mudjacking can require.
Every job starts with an assessment of what's actually causing the settling — a leaking irrigation line, poor original compaction, or normal expansive-clay movement all call for slightly different approaches, which is exactly why a vetted, experienced contractor matters more than the specific brand of foam used.
Driveway lifting happens right at your curb, often while you're still parking cars around it. Every contractor matched through Phoenix Concrete Lifting is vetted and insured before they're ever connected with a homeowner.

It depends on slab size, how far it needs to rise, and soil conditions underneath — there's no honest single number without a real assessment. Get matched with a contractor for a free, no-obligation quote specific to your driveway.
A properly done job addresses the void or soil issue causing the settling, not just the symptom, which is why choosing a vetted, insured contractor who explains their process matters. No fix is guaranteed forever, but a correctly stabilized slab should hold for years.
Many cracked slabs can still be lifted and stabilized — cracking alone doesn't automatically mean replacement. A contractor can assess whether your specific crack pattern and slab condition are a good candidate for lifting.
Most residential driveway lifting jobs are completed in a matter of hours, and the driveway is typically drivable again shortly after the work is finished — much faster than the cure time a full replacement pour requires.
