Uneven concrete is more than just a cosmetic issue. It’s a safety concern and a sign that your property may be experiencing soil movement, poor compaction, or long-term water damage. If you’ve noticed sinking driveways, sidewalks, patios, or warehouse floors, you’re not alone. These issues are common in the Pacific Northwest, where freeze-thaw cycles and shifting soil can take a toll on outdoor surfaces.
That’s where concrete lifting services come in. Also known as slabjacking, this repair method is a smart, cost-effective alternative to full concrete replacement. At Slabjack Geotechnical, we specialize in advanced concrete lifting techniques throughout Washington State and North Idaho, helping homeowners and commercial property owners restore safety, function, and curb appeal—without the mess or cost of ripping out and repouring slabs.
What is Concrete Lifting?
Concrete lifting, also known as slabjacking, is a repair method used to raise sunken or uneven concrete slabs back to their original position. Over time, soil beneath a concrete surface can shift, settle, or wash away, causing the slab above to sink or tilt. This is especially common with driveways, sidewalks, patios, garage floors, and even warehouse surfaces.
Instead of tearing out and replacing the entire slab, concrete lifting works by injecting material underneath the concrete, which fills empty spaces and gently lifts the slab from below. The result? A safer, level surface that looks and functions like new, without the high cost or long downtime of full replacement.
Methods of Slabjacking
There are two primary techniques used in concrete lifting services: mudjacking and poly-leveling. Both methods aim to restore uneven concrete surfaces by lifting them back into place from underneath, but the materials, technology, and results vary.
-
Mudjacking
Mudjacking is one of the oldest and most widely used forms of slabjacking. It involves drilling small holes in the concrete and pumping in a thick slurry made of water, sand, and cement. As the mixture fills the voids beneath the slab, it creates enough pressure to lift the sunken concrete back to its original position.
Benefits of Mudjacking:
- Cost-Effective – Generally more affordable than full slab replacement
- Quick Turnaround – Most jobs are completed in just a few hours
- Environmentally Friendly – Made from natural materials like soil and cement
- Tried and True – A reliable method used for decades across residential and commercial projects
However, because the slurry is heavy, there’s a slight risk that it could cause further settlement in weaker soils over time.
-
Poly-Leveling
Poly-leveling, or polyurethane foam injection, is a more advanced alternative to mudjacking. Instead of using a heavy slurry, this method injects a lightweight, expanding polyurethane foam beneath the slab. As the foam expands, it lifts the concrete evenly and solidifies within minutes, creating a strong, stable base.
Benefits of Poly-Leveling:
- Lightweight and Durable – Reduces stress on weak soils and holds up under heavy loads
- Fast Curing – The foam sets in minutes, allowing for same-day surface use
- Highly Precise – The expanding foam fills gaps and lifts slabs smoothly, without overcorrection
- Minimal Disruption – Requires fewer and smaller injection holes compared to mudjacking
This method is especially popular for concrete lifting in Washington and across the Pacific Northwest, where rapid results and long-term performance are essential for homes, businesses, and industrial spaces.
Mudjacking vs. Poly-Leveling: Which Method is Right for You?
Both mudjacking and poly-leveling are effective techniques, but the best choice depends on your specific needs, location, and how the concrete is being used. At Slabjack Geotechnical, we help property owners across the Pacific Northwest choose the right concrete lifting service based on durability, budget, and timeline.
Here’s a quick guide to help you decide:
Choose Mudjacking if:
- You’re looking for a cost-effective solution for residential walkways, patios, or driveways
- Your concrete is not under heavy structural loads (like garages or industrial floors)
- You’re fine with a slightly longer cure time and a more traditional approach
Choose Poly-Leveling if:
- You need a lightweight, long-lasting solution for warehouse floors, commercial spaces, or driveways
- You want a fast return to service, within minutes of the repair
- Precision, minimal mess, and long-term performance are top priorities
- You’re lifting concrete in areas with unstable or moisture-prone soils, common in Washington and the Pacific Northwest
Still unsure? Our team can inspect your site and recommend the best concrete lifting solution based on your slab’s condition and your goals. Whether it’s mudjacking or poly-leveling, we’ll make sure your concrete is safe, level, and built to last.

FAQs
What causes concrete to sink or become uneven?
Concrete slabs can settle due to soil erosion, poor compaction during installation, drainage issues, or freeze-thaw cycles, especially common in the Pacific Northwest. When the ground shifts or voids form beneath a slab, the concrete above loses support and sinks or cracks.
Is concrete lifting better than replacing the slab?
In many cases, yes. Concrete lifting services are typically faster, more affordable, and less disruptive than full replacement. Lifting also preserves the existing slab and reduces waste.
Can you lift cracked concrete?
Yes, we can lift cracked concrete. If the slab is uneven, we use polyurethane lifting with geopolymer injection to level and stabilize it before sealing the crack for long-term durability.
How long does it take for lifted concrete to be usable?
With poly-leveling, most surfaces are ready for light use within 15–30 minutes. Mudjacking may take longer to cure, up to 24–48 hours, depending on the materials and weather conditions.
