Lifting Sidewalk with PolyLevel in Oshkosh, WI

After numerous stumbles and falls, homeowners in Oshkosh, WI called Sure-Dry for a solution to their sunken concrete slabs.

Our PolyLevel system is the best solution for fixing sunken concrete slabs. Our foremen drill small penny sized holes into the concrete and insert polyurethane foam under the concrete slabs. The foam, unlike soil, will not wash out and is durable enough to hold the slab in the correct location for many, many years to come!

These homeowners couldn't be happier being able to walk and drive on the concrete just 15 minutes later. They were very happy knowing their concrete won't be an inconvenience ever again!

This driveway had sunk down a few inches below the garage doors, making it hard for the homeowners to drive into it, causing a trip hazard, and pooling with water every time it rains. To fix these issues, we permanently lifted and leveled the driveway back up to the correct height with our PolyLevel Injection Foam, making for a smooth entry into the garage.

These sunken driveway slabs were causing a tripping hazard and causing an issue for the homeowners.

Before: Sinking Concrete & Widening Cracks

This Oshkosh homeowner was seeing the effects of time and erosion on their large concrete driveway and garage apron. Slabs had started to sink and settle unevenly, creating trip hazards and pooling water near the foundation. Cracks were spreading and starting to let more moisture in—setting the stage for even more settling down the road.

After: Lifted, Leveled & Sealed Tight

Our crew lifted the sunken slabs using PolyLevel®, an expanding foam that fills voids and restores stability without heavy equipment or mess. Once the surface was back to level, we sealed all the joints and cracks with NexusPro®, a durable, waterproof sealant that moves with the concrete and stands up to the weather.

The result? A smooth, safe, and protected driveway and apron—with proper drainage restored and no more eyesores or hazards.

Concrete Sidewalk Repair & Leveling in Oshkosh, WI

After

Before:
This homeowner in Oshkosh, WI had a sidewalk that had sunk several inches over time, creating a serious trip hazard leading up to the home. The uneven concrete wasn’t just unsafe — it was also sloping back toward the house, allowing water to collect near the foundation instead of draining away properly.

Like many homes in Wisconsin, years of freeze/thaw cycles, shifting soils, and water washout underneath the slabs had caused the concrete to settle and crack.

After:
Instead of tearing out and replacing the sidewalk, our team repaired and restored it using PolyLevel® concrete lifting foam and NexusPro® joint sealant.

We carefully lifted and leveled the sunken sidewalk using PolyLevel, an expanding polyurethane foam designed to fill voids beneath the concrete and stabilize the supporting soil. Once the slabs were properly positioned again, we sealed all joints and cracks with NexusPro to help prevent water from getting underneath and causing future settlement.

This concrete leveling and repair solution provided the homeowner with:

A safer, level sidewalk with trip hazards eliminated
Proper drainage away from the foundation
Long-term protection against water intrusion and soil washout
A faster and more affordable alternative to concrete replacement

Now the sidewalk is:
✔️ Level
✔️ Safe to walk on
✔️ Draining water away from the home properly

For homeowners in Oshkosh dealing with sinking sidewalks, uneven concrete, cracked driveways, or trip hazards, concrete lifting with PolyLevel offers a long-lasting repair solution without the cost and disruption of tearing out and replacing concrete.
