Before & After Photos

In the before photo, it is clear to see the concrete has sunken into the Earth. To raise it up, the crew drilled 4 pence sized holes into the concrete and injected polyurethane foam. This foam is waterproof and will not ever be washed out. 

Before:
A homeowner in Suamico, WI had two settling sidewalk sections leading up to their home, creating uneven surfaces and visible trip hazards. Seasonal freeze–thaw cycles and moisture-sensitive soils had caused the slabs to sink at different rates, leaving gaps, tilted panels, and poor drainage along the walkway. The settlement worsened each year as voids formed beneath the concrete.
After:
Sure-Dry lifted and restored both sidewalks using PolyLevel®, injecting the high-density structural foam beneath the settled slabs to raise them back to their original elevation. The material expanded to fill voids and stabilize the soil, creating a smooth, level surface with long-term support that holds up through Wisconsin’s seasonal ground movement.
The walkways are now safer, properly aligned, and visually improved for the homeowner.

The stability of any concrete surface is dependent on the soils beneath it. The weight of concrete and what it supports, combined with natural soil erosion, can lead to sunken and uneven concrete surfaces, like this long concrete patio in Abrams, WI.  

Sure-Dry Basement Systems provides expert concrete repair solutions using the PolyLevel® system. PolyLevel® is an expanding polyurethane foam that is injected beneath the concrete to fill the gaps caused by soil erosion and raise and stabilize the concrete surface.

Before:
A homeowner in Abrams, WI discovered that sections of their garage floor had begun to sink and crack, creating uneven surfaces and visible gaps at the foundation wall. Years of soil settlement and moisture washout beneath the slab had left portions of the concrete unsupported, causing vehicles to roll unevenly and small cracks to widen each season.

After:
To restore stability and level the surface, our team used PolyLevel® expanding foam to lift and support the sunken concrete. Injection ports were drilled at key points across the affected areas, and the lightweight polyurethane foam was introduced beneath the slab to fill voids and raise it back to its original elevation.

Now, the Abrams garage floor is level, solid, and ready for daily use—with the voids permanently filled and the structure protected against future settlement.

In Lena, WI, a homeowner faced the hazard of unlevel stairs, posing a risk to safety and the home's appearance. As you can see in the before photo, the difference was quite noticeable. Our team at Sure-Dry stepped in, employing PolyLevel and NexusPro to seamlessly elevate and stabilize the stairs. The after photo showcases the transformation – now, they're not just level but also safer and more visually appealing. This outcome exemplifies our commitment to delivering long-lasting solutions and a homeowner experience that stands out.
