Before & After Photos

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.

Notice in the before photo the uneven and sunken concrete creating trip hazards and preventing outdoor project progress in Cleveland, WI. Our expert technicians stepped in with trusted solutions, deploying our PolyLevel system to lift and stabilize the slabs efficiently. We followed this by applying NexusPro Joint Sealant to ensure lasting stability by sealing joints and preventing water erosion. Finally, with the application of SealantPro, we extended the concrete’s life, protecting it against future wear. The after photo highlights the rejuvenated and safeguarded surface, primed for any upcoming projects. Our proven techniques offer solid assurances and peace of mind.

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.
