Sunken and uneven concrete is one of the most common problems Everett homeowners face, especially on driveways, patios, and walkways built over the region's dense glacial till and soft river-delta soils. When concrete settles unevenly, it creates trip hazards, water pooling, and structural stress that only gets worse through our long wet winters. Concrete leveling and slab lifting is a fast, cost-effective alternative to full replacement that raises settled slabs back to grade without tearing out the old concrete. We use proven mudjacking and polyurethane foam injection methods to stabilize your concrete and restore safe, level surfaces. Whether your driveway has dropped near the garage in Rucker Hill, your patio has settled on the Riverside flats, or your walkway steps are uneven in Cascade View, we can diagnose the cause and lift it right.

Why Concrete Settlement and Slab Lifting Matter in Everett
Everett's unique geology drives concrete failure in ways that flat, well-drained regions never see. The uplands sit on dense glacial hardpan that sheds water instead of absorbing it, while the Snohomish River flats and Bayside areas hold soft silt and peat that compress and shift under the weight of concrete. Add 37 inches of annual rain, occasional hard freezes, and tree root heave from Douglas firs, cedars, and bigleaf maples, and settled concrete becomes inevitable. A driveway that was level five years ago can drop two to four inches on one side, creating a tripping hazard and allowing water to pool and accelerate deterioration.
- We identify the root cause of settlement, whether poor soil compaction, subsurface erosion, or tree root lift.
- We raise sunken driveways, patios, and walkways back to original grade without demolition or replacement.
- We stabilize the underlying soil and inject support material to prevent future settlement.
- We restore safe, level surfaces and eliminate pooling water that damages concrete and attracts moss and algae.
Addressing settled concrete quickly prevents bigger repairs down the road and keeps your property safe and compliant with ADA standards for commercial walkways and public-facing surfaces.
Local reality: A Rucker Hill homeowner's driveway dropped 3 inches where it meets the garage slab, creating a trip hazard and allowing water to back up under the foundation. Mudjacking raised it back to grade in one afternoon, saving a costly foundation repair.

How We Lift and Level Concrete in Everett: Our Process
Concrete leveling is not a one-size-fits-all job. We start with a detailed site inspection to understand the soil type, drainage patterns, and reason for settlement. On the uplands, we often find hardpan and poor drainage; in the flats, we find soft silt and water saturation. We then choose the best lifting method, prepare the site, drill strategic injection ports, and pump material under the slab to raise it incrementally and safely. The entire process takes hours, not days, and you can use the surface again within 24 to 48 hours depending on method and weather.
- We perform a free on-site inspection and identify the cause of settlement and the best lifting approach.
- We mark injection points and prepare the surface to protect landscaping and adjacent structures.
- We drill small diameter holes through the concrete slab at calculated intervals.
- We pump mudjacking slurry or expanding polyurethane foam under the slab, raising it gradually to the target grade.
- We monitor the lift in real-time to avoid over-correction and ensure even, level results.
- We fill the injection holes with concrete and clean the site.
The result is a safe, level surface that drains properly and prevents future water damage and settling.
Example: A Riverside homeowner's patio had settled 2 inches on the downhill side, pooling water and creating a muddy, slippery hazard. We injected polyurethane foam under the slab, raised it back to level, and sealed the surface. The patio now sheds water and is safe and attractive again.

Concrete Leveling and Slab Lifting Methods
| Method | Description | Best For |
|---|---|---|
| Mudjacking | Inject a slurry of soil, cement, and water under the slab to lift it gradually and fill voids. | Large driveways, patios, and commercial slabs; areas with stable subsoils. |
| Polyurethane Foam Injection | Inject expanding closed-cell polyurethane foam under the slab; foam expands and hardens, lifting the concrete and sealing voids. | Residential driveways, walkways, and patios; areas with poor or soft soil; precise lift requirements. |
| Slab Jacking with Polymer | Inject a lightweight polyurethane-based material that cures quickly and provides long-term support. | Residential and light commercial; areas where minimal weight and fast curing are important. |
| Full Replacement | Remove and replace the settled concrete with new, properly graded and compacted slab. | Severely cracked or deteriorated slabs; situations where leveling alone cannot achieve safe, lasting results. |
Each method has strengths; we recommend the best fit after inspecting your soil, slab condition, and lift requirements. Mudjacking works well on Everett's upland hardpan, while foam injection excels in softer delta soils and residential settings where precision and speed matter.
Concrete Leveling and Slab Lifting Cost in Everett: What to Expect
Concrete leveling costs in Everett typically start at $4 per square foot for straightforward mudjacking jobs on stable soils. A 500-square-foot driveway might run $2,000 to $3,000, while a 1,000-square-foot patio could range $4,000 to $6,000 or more depending on the method, soil conditions, and degree of lift required. Polyurethane foam injection tends to cost more than mudjacking because of material and precision, but it offers faster curing and works better in soft, saturated soils like those in the Snohomish River flats. The size of the slab, the amount of lift needed, soil type, access for equipment, and proximity to structures all affect the final price.
We always recommend getting 2 to 3 estimates from insured contractors so you can compare methods, pricing, and warranty terms. A reputable contractor will explain why they recommend a specific method and what factors drive the cost. Always ask whether the price includes site cleanup, small hole filling, and any surface sealing. Some jobs are straightforward and fit the starting rate; others require extra drilling, material, or time and will cost more.

What to Look for When Hiring a Concrete Contractor Near Me in Everett
Choosing the right contractor for concrete leveling is critical. You want someone who understands Everett's soil and climate, carries proper insurance, listens to your concerns, and delivers transparent pricing. Many homeowners make the mistake of choosing based on price alone; that often leads to poor workmanship, delayed timelines, and disputes over warranty. Instead, focus on experience, communication, and insurance coverage.
Start by asking for references from recent Everett projects, especially homes in your neighborhood or on similar soil types. Call those references and ask whether the work was completed on time, whether the surface has remained level, and whether the contractor was professional and clean. Request proof of general liability insurance and workers compensation coverage on every job; this protects you if someone is injured or property is damaged during the work. Get detailed written estimates from at least two contractors so you can compare methods, timelines, and pricing. Understand what is included in the estimate and what is not, such as site cleanup, sealing, or permit costs. Ask about warranty terms; reputable contractors stand behind their work for 1 to 3 years depending on method and conditions.
- Verify that the contractor carries current general liability and workers compensation insurance before work begins.
- Request and check references from at least three recent Everett-area jobs on similar concrete types.
- Get written estimates from 2 to 3 contractors so you can compare method, timeline, and price.
- Ask whether HOA approval or municipal permits are required for your project and who handles them.
- Clarify whether the price includes site cleanup, hole filling, and any surface sealing or protection.
- Confirm the warranty period and what it covers, such as re-settlement or material failure.
A professional contractor will answer your questions patiently, provide a clear timeline, and explain why they recommend a specific method. Avoid contractors who pressure you to sign immediately, offer prices far below market, or refuse to provide insurance documentation. Ready to move forward?
