Before & After Photos

In Green Bay, WI, a homeowner faced sinking and cracking front steps and sidewalk near their entrance, raising safety concerns. As you can see in the before photo, the uneven surfaces created tripping hazards and detract from the home’s curb appeal. Sure-Dry's trained specialists expertly applied our PolyLevel system to lift and stabilize the concrete with high-strength polyurethane foam, restoring a level surface. We also sealed cracks and joints with our durable NexusPro Joint Sealant for lasting protection against water and freezing temperatures. Notice in the after photo the transformation and enhanced safety and appearance.

Before: Sinking Concrete and Failing Joints

This homeowner in Green Bay had noticed their sidewalk and driveway beginning to settle. Slabs had started to dip and pull apart from each other, causing uneven edges, widening joints, and minor trip hazards. Water was beginning to pool in low areas and seep into the cracks—raising concerns about erosion and future damage.

After: Lifted, Sealed, and Structurally Sound

To restore the concrete, Sure-Dry used PolyLevel® to lift and level the sunken slabs. This expanding foam fills voids and raises the concrete without the need for demolition. Then, we applied NexusPro® joint sealant, a durable and flexible solution that helps prevent future washout and keeps water from penetrating beneath the surface.

Now, the surface is level, sealed, and ready for long-term use—without the cost or disruption of a full replacement.

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.
