PolyLevel® Injection Foam Concrete Leveling

PolyLevel® is an expanding, high-density polyurethane foam injected beneath sunken concrete to fill the voids left by soil erosion, raise the slab back to its original position, and stabilize the soil so settlement does not recur. It is the modern replacement for mudjacking and full slab replacement in Minnesota and Wisconsin.

Expanding Polymer Foam That Lifts, Levels, and Stabilizes

The stability of any concrete surface depends on the soil beneath it. The weight of concrete, combined with natural soil erosion, leads to sunken and uneven surfaces. PolyLevel® addresses the cause: a two-part polyurethane foam is injected through penny-sized holes in the slab, where it expands to fill voids, lift the concrete, and strengthen the soil’s load-bearing characteristics.

Despite weighing only about 4 lbs per cubic foot, compared with roughly 120 lbs per cubic foot for traditional fill material, PolyLevel® supports substantial loads and typically delivers greater lifting power than mudjacking, without adding weight to already weak soils.

Lifts settled slabs, slab foundations, and sunken sidewalks
Strengthens and stabilizes loose soil beneath the slab
Fills sinkholes and other voids
Lifts and stabilizes roadways, rail beds, and airport runways
Preconstruction soil treatment to improve load bearing
Waterproof once cured; will not wash away or leach chemicals

PolyLevel® vs Mudjacking and Slab Replacement

Traditional repairs either pump a heavy slurry under the slab or tear it out entirely. The comparison below shows why PolyLevel® outperforms both.

Traditional methods

Mudjacking / Replacement

Heavy water, soil, sand, and cement slurry pumped through large drilled holes. Messy on-site mixing. Adds load to weak soil. Hours to days of cure time. Mudjacking holes leave a visible, unfinished look. Replacement damages landscaping and keeps concrete off-limits while it cures.

Recommended Solutions

PolyLevel® Injection

Lightweight foam with greater lifting power. Metered, spaced injections give precise, controlled lift, and the chemical mix can be adjusted for further precision. Penny-sized injection holes preserve appearance. Cures in minutes, so driveways can be used the same day. Strengthens the underlying soil so settlement does not recur.

PolyLevel® Installation: What to Expect

1.

Free on-site inspection and estimate

A DBS design specialist inspects your concrete, explains what caused the settlement, how it can be fixed, and exactly what it will cost in a written proposal.

2.

Injection ports drilled

Penny-sized holes are drilled in the settled sections of the slab at engineered injection points.

3.

Foam injection and lift

Two-part PolyLevel® polyurethane is injected beneath the slab, expanding to fill voids and raise the concrete. Trained installers control the injection so just enough foam is used to reach level.

4.

Holes patched, cracks sealed

Injection holes are patched and cracks or joints can be sealed for a uniform, finished appearance.

5.

Back in service within minutes

PolyLevel® cures very quickly. You can drive over a lifted driveway slab in as little as 15 minutes after installation.

Why Level Interior Slabs with PolyLevel®

Strong but Light

About 4 lbs per cubic foot vs 120 lbs for standard fill, ideal where denser material would overload weak soils, yet it supports substantial loads.

Fast Cure

Cures in minutes, not days. Driveways, patios, sidewalks, and pool decks return to service almost immediately.

Precise, Controlled Lift

Metered, spaced-out injections carefully control lifting power. The chemical composition can be adjusted for even greater precision.

Waterproof & Inert

Once cured, PolyLevel® will not wash away, does not react with soil or moisture, and will not leach harmful chemicals.

Discreet Repair

Injections need less than an inch per port, keeping the finished look of your driveway, garage floor, or pool deck intact.

Network Exclusive

PolyLevel® is a proprietary product developed by Supportworks, available exclusively from DBS and other contractors in the Supportworks network.

DBS was very professional, punctual and went above and beyond to fix our concrete needs. I would highly recommend them. We made a post on Facebook suggesting them to our friends and family. Thanks!

The crew that did our concrete leveling arrived on time and got right to work. Both Pierce and Ruben worked steadily on the job for three hours straight. When I periodically reviewed their progress, they were very cordial and patient with me explaining how the work was going and the cautions they were taking to not cause any cracks to our pool coping. They showed a high level of skill, and I am very pleased with their work. I recommend this company highly.

The service technician arrived on time and was well-prepared. Before starting, he took the time to discuss my concerns and incorporated them directly into his work. He spent the entire day working on the concrete until it was perfect, and he thoroughly cleaned all debris from the pool area before leaving. DBS provided exceptional service and quality work at the best price, especially compared to the higher bids I received from other companies. I would not hesitate to recommend DBS to my friends and family.

Every part of our project was handled exceptionally. Our estimate from Travis was courteous, professional and knowledgeable. He was able to provide us with reasonable options for our project. We were given a reminder and courtesy call when someone was on their way to our home. All our appointments were on time. The project foreman, Shane was at our home working throughout the project. His knowledge and expertise was critical in accurately in lifting our concrete apron and crack repair in the garage floor. Shane and Cameron worked very well together. We are very happy that we chose DBS to complete our project and have already recommended DBS to others.

Griffin and his colleague were very helpful and explained everything that they were going to do in August 2026 regarding some concrete sealing on a repaired sidewalk piece. They even finished a little earlier than he had initially expected to.

We had a great experience using DBS for a small concrete lifting project. Joe Bong and crew were very knowledgeable and shared the complete process with me while doing the work. They showed up as planned and did professional work! I would definitely recommend their polyjacking service to others!

The team showed up and were very conscientious about protecting our property while completing their work. The communication was great, they kept us informed all the way through the process. The employees that did the concrete leveling did a great job and were very professional. We would use your services again!
The communication with this company was excellent. They contacted me promptly, followed through with the appointment and were on time and super efficient. The presentation was professional and the cost was what we expected. But best of all, we can afford the solution to our concrete problem! A win for us! 7/20/26 Update: Well, the concrete driveway project is complete! And It turned out great. Joe was the foreman on the job and he was so professional and nice. He called before they came, updated me several times during the day, and sent me a series of pictures of the finished job. The entire experience deserves an A+. This company is top notch!

Myke came by to give me a quote for a garage concrete lift and leveling project. I appreciated the extra time he spent answering my questions and making sure I understood the work that would be completed. I’ve had a few quotes from other companies in the area and he was very helpful in understanding my options and what would make sense for me (both in terms of cost and long term impact).
