Concrete Leveling Before & After Photos

In the Fond Du Lac project, unlevel and cracked concrete was making this home's exterior both unsightly and unsafe. As you can see in the before photo, the damage was extensive. We employed the PolyLevel system to expertly stabilize, lift, and level the concrete slabs, restoring them to a stable and secure position next to surroundings sentenced structure. To prevent future issues, we used NexusPro to seal the cracks and joints, protecting the concrete from water infiltration. In the after photo, the revitalized and durable surface reinforces why homeowners trust Sure-Dry for dependable concrete repair solutions.

Before: Uneven Walkways and Patio Hazards

Across this 20+ unit condo community in Fond du Lac, years of settling had left sidewalks and patios cracked, uneven, and unsafe. Slabs had shifted, created trip hazards, and water was beginning to drain toward the buildings in some areas. It was time for a permanent fix that wouldn’t disrupt residents for weeks on end.

After: Lifted, Sealed, and Safe Again

Using our fast-curing PolyLevel® lifting system, we raised and leveled over 20 individual areas across the property. From sunken sidewalks to dipping patio slabs, we restored everything to a safe, even grade. Then we sealed cracks and joints with NexusPro®, a waterproof sealant designed to protect against future erosion and freeze-thaw damage.

Now the walkways and patios are safer, smoother, and ready for everyday use—with minimal disruption to residents and no demolition required.

Before

The concrete area between the garage and the building at this Fond du Lac, WI property had settled over time, creating uneven slabs that made walking between the structures less safe and more inconvenient. The sunken concrete also allowed water to collect in low spots, increasing the potential for erosion beneath the slab and additional settlement. Like many properties in Wisconsin, seasonal freeze-thaw cycles and changing soil moisture had contributed to the problem. The property owner wanted a cost-effective concrete leveling solution that would restore the existing concrete instead of replacing it.

After

Our crew inspected the affected slab, identified the underlying voids, and injected PolyLevel High-Density Concrete Lifting Foam beneath the concrete to precisely lift and stabilize the settled sections. Unlike traditional mudjacking (slab jacking), which uses a heavy cement slurry that can place additional weight on unstable soils, PolyLevel is lightweight, expands to fill hidden voids, cures in minutes, and delivers long-lasting support with minimal disruption. The completed project provided a smooth, safe walkway between the garage and building while extending the life of the existing concrete.

Before:
A Bryant homeowner had several settled concrete slabs (driveway/walkway areas) that created uneven transitions and trip hazards. Low spots collected water after rain, and open joints and cracks allowed more moisture to reach the base—worsening settlement through freeze–thaw cycles.

After:
We lifted and stabilized the affected slabs with PolyLevel®, injecting lightweight polyurethane beneath the concrete to fill voids and restore proper elevation and pitch. After leveling, we routed and cleaned all cracks and control joints and sealed them with NexusPro® to block water intrusion and accommodate seasonal movement.

The surfaces are now even, safer to use, and protected for the long term—without the cost and disruption of tear-out and replacement.

Before: Sunken Concrete and Cracked Joints Threaten Safety and Appearance

A homeowner in Hortonville, WI reached out to Sure-Dry with concerns about their uneven driveway and front walkway. Over time, soil settlement had caused concrete slabs to sink, creating tripping hazards and unsightly gaps between joints. In addition to structural concerns, water was infiltrating through open joints, further eroding the base soil and threatening long-term damage.

The homeowner wanted a clean, lasting fix—but without the cost and disruption of full concrete replacement.

After: Lifted, Sealed, and Protected

Sure-Dry provided a complete three-part concrete solution:

• PolyLevel® foam injection was used to lift and stabilize the sunken slabs quickly and precisely.

• NexusPro® joint and crack sealant filled and protected the control joints and cracks, preventing further water intrusion.

• SealantPro® concrete sealant was applied to preserve and protect the surface from moisture, oil, and seasonal wear.

The result was a smooth, level, and visually refreshed concrete surface—safe, sealed, and protected for years to come.
