Why Puget Sound Driveways Settle Faster Than You'd Expect
The rainfall common in the Puget Sound area creates challenges to our driveway concrete slabs and results in driveway cracking. Often we find settling near the corner connection points or where the driveway meets the structure. Sometimes water moves under the slabs causing erosion over time until a crack occurs and results in significant settling. Our process quickly rectifies this, bringing up any sunken pieces, large and small, restoring your driveway to its orginal look! We are experts in raising, leveling any sunken slabs or re-leveling a driveway without the need to replace any concrete! You save hundreds of dollars and the entire driveway will match in age and color at the end of the process.
How Lifting a Sunken Driveway Works
Assessment. Our technician walks your driveway, identifies settled panels, probes for voids, and determines whether any sections are beyond repair. We'll be upfront if that's the case — but in most situations, what looks severe is fully correctable.
Drilling. Small holes — typically 5/8 to 3/4 of an inch — are drilled through the slab at carefully planned injection points. This takes only minutes per panel.
Foam injection. High-density polyurethane foam is pumped beneath the slab, expanding to fill voids and lift the concrete back into place. Our technicians monitor the lift in real time for a precise, even result. The foam cures within minutes.
Patching and finish. Injection holes are patched with a cement mix, the work area is cleaned, and your driveway is ready to use — all on the same day.
Most residential driveway projects are complete in two to four hours.
Driveway Lifting vs. Replacement: A Simple Comparison
Full driveway replacement means demolishing and hauling away the existing slab, re-grading and compacting the subbase, forming and pouring new concrete, and waiting up to a week before you can drive on it again. In the Seattle area, that typically runs $8,000–$15,000 or more — and a new slab can settle again if the underlying soil isn't properly addressed.
Slabjacking lifts and stabilizes your existing slab in a single visit, at typically 25–50% of replacement cost, with no waiting period. It also directly addresses the void and soil instability that caused the problem in the first place.
The honest caveat: if a slab is extensively shattered or has heaved from tree roots, replacement may genuinely be the right call. Our estimators will tell you plainly if that's the case. But for the vast majority of settled or cracked driveways, lifting is the smarter solution.

Driveway Slabjacking FAQ
How long do results last? Polyurethane foam doesn't degrade, compress, or wash out. When the underlying soil is properly stabilized, lifted driveway slabs can remain level for many years.
Will the injection holes be noticeable? Patched holes are small and blend with the surrounding surface. They're visible on close inspection but not prominent, and weathering makes them increasingly difficult to spot over time.
What if my driveway has been repaired before? In most cases, yes — polyurethane foam can still be injected in new locations to address additional settling, even if a prior repair used traditional mudjacking material.
Is this a permanent fix? It's a long-lasting one. The foam is rated for decades of service and is specifically chosen for the moisture and soil conditions common throughout the Pacific Northwest.
