Concrete Leveling & Slab Lifting in Portland is a fast, cost-effective solution for sunken driveways, patios, walkways, and foundation slabs that have settled over time. Portland's expansive clay soils and seismic activity create ideal conditions for concrete to shift and crack, leaving homeowners with trip hazards, water pooling, and accelerated surface damage. Rather than tear out and replace an entire slab, leveling lifts settled concrete back to grade using proven techniques that restore safety and appearance in a single day. We've been serving Portland and the surrounding Willamette Valley since 2016, helping homeowners across Beaverton, Tigard, Lake Oswego, and beyond fix uneven concrete without the cost or hassle of full replacement. If your driveway is sinking or your patio has become a tripping hazard, we can schedule a free estimate and show you exactly what's possible.
Why Concrete Leveling & Slab Lifting Matters in Portland
Sunken concrete is more than an eyesore. It creates safety risks for family and guests, accelerates water damage to foundations and basements, and can lower property value if left unchecked. Portland's clay-rich soils expand and contract seasonally, and seismic movement compounds the problem. Most driveways and patios settle within 5 to 10 years of installation, especially in areas with poor initial drainage or on sloped lots common throughout the Portland metro area.
- We lift settled concrete back to original grade without demolition, saving time and money compared to full replacement.
- Leveling eliminates trip hazards and improves water drainage away from your home and foundation.
- The process is fast, typically completed in one day, so your driveway or patio is ready to use immediately.
- Lifting is permanent when done correctly, addressing the root cause of settlement rather than patching symptoms.
Early action prevents expensive foundation damage and extends the life of your concrete investment by years.
Key info: Portland homeowners often wait too long to address sunken concrete. A 2-inch drop on a driveway in Lake Oswego or Tigard can lead to water intrusion under the slab, causing soil erosion and further settlement. The sooner you lift, the sooner you stop the cycle.

How Concrete Leveling & Slab Lifting Works in Portland
Our process begins with a site visit and assessment of soil conditions, slab thickness, and the extent of settlement. We identify the cause, whether it's soil compaction, poor drainage, or foundation shift common in Portland's variable terrain. Once we understand what we're working with, we inject a specialized polyurethane or cement-based lifting foam beneath the slab through small holes. The foam expands, filling voids and gradually raising the concrete back to level. We monitor pressure and density in real time to ensure even lifting and prevent over-correction.
- We drill small access holes (typically 1 to 1.5 inches) in patterns across the settled slab to reach the void space below.
- Our crew injects expanding foam or self-leveling cement under controlled pressure, filling voids and lifting the slab incrementally.
- We monitor lift progress continuously using laser levels and reference points to achieve precise, even leveling.
- Once the slab reaches target height, we seal all injection holes with concrete epoxy, leaving a clean, seamless finish.
- The concrete is ready to use immediately, with no curing time required before traffic or furniture can return.
The entire job typically takes 4 to 6 hours, depending on slab size and complexity.
Real example: A homeowner in Gresham had a 600-square-foot driveway that had settled 3 inches over eight years, creating a visible lip at the garage entry. We lifted it back to grade in one day using polyurethane foam injection. The driveway is now level, water drains properly, and the entry is safe for family and visitors.

Concrete Leveling & Slab Lifting Methods Compared
| Method | Description | Best For |
|---|---|---|
| Polyurethane Foam Injection | Lightweight expanding foam injected under pressure to fill voids and lift slab. Cures in minutes, adds minimal weight, and provides excellent long-term stability. | Most residential driveways, patios, and walkways. Fast, clean, and minimal disruption. |
| Self-Leveling Cement Slurry | Dense cement-based material injected to fill voids and stabilize the slab. Heavier than foam, excellent for high-traffic areas and poor soil conditions. | Commercial slabs, garage floors, and areas with weak subgrade requiring extra weight and stability. |
| Mud Jacking (Slab Jacking) | Traditional method using a slurry of soil, sand, and cement pumped beneath the slab. Larger holes, slower cure, but proven for deep voids and large areas. | Large patios, extensive settlement, and situations where material cost is primary concern over speed. |
| Helical Piers and Piering | Mechanical lifting using adjustable steel piers installed beneath the slab. Allows for future fine-tuning and is reversible if needed. | Foundation slabs with ongoing settlement issues or where future adjustment capability is desired. |
We recommend polyurethane foam for most Portland residential jobs because it's fast, clean, and ideal for our local soil and climate conditions.
Concrete Leveling & Slab Lifting Cost in Portland: What to Expect
Pricing for concrete leveling and slab lifting typically starts at $4 per square foot for straightforward residential jobs. A 600-square-foot driveway might run $2,400 to $3,600, depending on how much the slab has settled, soil conditions, and access for equipment. Larger patios or multiple slabs, or jobs in areas with difficult access like steep driveways in West Linn or Hillsboro, cost more. Factors that increase price include deep settlement (more foam or material needed), poor soil conditions requiring stabilization, and proximity to structures or utilities that require careful drilling.
We recommend getting 2 to 3 estimates before committing. Pricing can vary based on method choice, material type, and local soil assessment. Visit our pricing page for detailed breakdowns by service type and area, or request a free estimate and we'll assess your specific situation and provide an exact quote.
Most jobs are completed in one day, so labor costs are predictable and there's no extended timeline eating into your budget. We handle travel throughout Portland and surrounding areas at no extra charge.
Concrete Leveling & Slab Lifting Near Me: What Portland Homeowners Should Know
Choosing the right contractor for concrete leveling is critical because the work is permanent and affects your home's safety and value. Look for a company that is licensed and insured for concrete work in Oregon, carries liability coverage, and can provide proof of workers compensation insurance. Ask for references from recent jobs in your neighborhood, whether Tigard, Lake Oswego, Gresham, or Portland proper. Check online reviews and verify they are in good standing with the Better Business Bureau and local licensing authorities.
Understand what permits may be required. In Portland, sidewalk and driveway work sometimes requires municipal permits, especially if your slab is in the right-of-way or involves curb cuts. A reputable contractor will clarify permit requirements upfront and handle them if necessary. If you live in a homeowners association, check your CC&Rs for restrictions on concrete work or appearance changes. Some HOAs require approval before leveling work begins.
Ask about the specific method the contractor recommends and why. Not all lifting techniques are equal, and the best choice depends on your soil type, slab condition, and long-term goals. A contractor who takes time to explain the process and answer questions is more likely to deliver quality work. Request a written estimate that includes the method, material type, expected timeline, and warranty or guarantee on the work.
