Concrete Repair & Leveling in Seattle
Cracked, sunken, or settling concrete? We repair and re-level driveways, walkways, patios, and slabs — and fix the soil issues underneath so it actually lasts.
Concrete problems, fixed at the source
Seattle's wet ground, freeze-thaw swings, and settling soils are hard on flat concrete. Slabs sink as the soil beneath them washes out or compresses, edges crack, and surfaces spall. Most of it is repairable — and far cheaper than tear-out and replacement.
The key is fixing what's underneath, not just the surface. We lift sunken concrete by filling the voids below it, seal and reinforce cracks, and correct the drainage that caused the problem — so the repair holds instead of resurfacing in a year.
When it's time to repair
Catch these early and leveling is almost always cheaper and faster than replacement.
Sunken or uneven slabs
Sections that have dropped below the rest of the surface.
Trip hazards
Raised lips where slabs meet — a fall and a liability waiting to happen.
Pooling water
Water that sits on the slab or runs back toward the house.
Cracks & spalling
Widening cracks or flaking, pitted surfaces from moisture and wear.
Settling at the garage or steps
Aprons, steps, and approaches that have dropped or separated.
Gaps under the slab edge
Visible voids or soil washout beneath the concrete.
Concrete repair & leveling services
We lift, repair, and refinish — and only recommend replacement when a slab is genuinely past saving.
Slab Leveling (Mudjacking)
Pumping a slurry beneath the slab to raise it back to level — proven and economical.
Foam / Poly Leveling
Lightweight polyurethane foam injected through small holes to lift precisely and stay waterproof.
Driveway & Walkway Repair
Repairing or replacing failed sections of driveways, walks, and patios.
Crack & Spall Repair
Sealing cracks and resurfacing pitted, flaking concrete to stop further damage.
Void Filling
Filling the soil voids that let slabs sink, so the lift actually lasts.
Repair vs. Replace Guidance
An honest call on whether to lift, patch, or pour new — based on your slab, not our margins.
Repair or replace? How we decide
Not every piece of damaged concrete needs to be torn out. The deciding factors are why it failed and whether the slab itself is still sound. If a structurally good slab has simply sunk because the soil beneath it washed out or settled, leveling is almost always the right call — it is faster, far cheaper, and the slab you already have usually outperforms a fresh pour on disturbed soil.
We recommend replacement only when the concrete is genuinely past saving: broken into multiple pieces, severely spalled all the way through, or too thin to carry its load. Even then, we fix the base and drainage first so the new pour does not repeat the failure. The honest version — which one your concrete needs — is exactly what the free estimate is for.
Two ways to lift a sunken slab — compared
Both raise concrete by filling the void underneath. Here is how they stack up, so you know exactly what you are paying for.
| Factor | Polyurethane foam | Mudjacking (slurry) |
|---|---|---|
| Injection holes | Small, about 5/8 inch | Larger, about 1 to 1.5 inches |
| Cure and use time | Sets in minutes — usually same-day use | Needs about a day to cure |
| Added weight | Very light; will not overload weak soil | Heavy slurry adds load to the ground |
| Water resistance | Waterproof; will not wash out | Can erode over time |
| Best for | Most slabs, wet sites, and precise lifts | Heavy slabs and budget-driven jobs |
We use whichever genuinely fits your slab and soil — and we will tell you honestly when mudjacking is the better value.

What does concrete repair cost in Seattle?
Concrete leveling typically runs about $600 to $2,500 per area, depending on the size of the slab and the lifting method. Crack and spall repairs are usually modest. A full tear-out and re-pour costs several times more, which is why leveling and repair are the first option whenever the slab is sound.
Your free estimate gives you a firm, written price, and we will tell you honestly whether leveling, patching, or replacement is the better value for your specific slab.
Concrete Repair, answered
Usually far cheaper — often a fraction of the cost of tear-out and re-pour, with none of the downtime or new-versus-old color mismatch.
When we fill the voids that caused the sinking, a proper lift lasts for years. Foam leveling is waterproof and doesn't break down, so it holds especially well in our wet climate.
Mudjacking is economical and great for heavy slabs; foam is lighter, faster, and waterproof. We'll tell you which fits your slab and budget at the free estimate.
Yes — we seal and reinforce cracks and resurface spalled concrete, and we address the drainage or soil issue behind it so it doesn't simply return.
With foam (polyurethane) leveling you can usually walk and drive on the surface the same day. Mudjacking needs a little longer to cure. We give you the exact timeline for your job.
Leveling lifts your existing slab, so there is no color mismatch at all. For crack and surface repair we work to blend it in, though some difference between old and new concrete is normal.
