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.

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.
