Several concrete slabs around Lawrence University in Appleton had settled and shifted, creating noticeable trip hazards along walkways and building entry points. The uneven joints weren’t just unsightly—they posed safety concerns for students, staff, and visitors.
Sure-Dry used PolyLevel® expanding foam to gently and precisely lift the sunken slabs, restoring an even walking surface across the problem areas. Once lifted, we applied NexusPro® joint and crack sealant to permanently seal gaps and prevent water from getting underneath the concrete—helping prevent future settling.
The result? A safer, cleaner, and more professional-looking campus surface—completed quickly and with minimal disruption.
Before: A homeowner in Appleton, WI was dealing with an aging concrete driveway and front walkway that had developed significant settling and numerous cracks. Over time, the uneven concrete created noticeable height differences between slabs, resulting in potential tripping hazards and an unattractive entrance to the home. The homeowner wanted to restore the concrete without the expense and disruption of complete replacement.
After: Sure-Dry used the PolyLevel Concrete Leveling System to lift and stabilize the settled driveway and walkway slabs. Unlike traditional mudjacking, PolyLevel uses lightweight polyurethane foam to raise concrete without adding significant weight to the underlying soil. The team then applied NexusPro Joint and Crack Sealant to seal existing cracks and joints, helping prevent water from reaching the soil beneath. The result is a more even, attractive driveway and walkway with improved safety and long-term protection.

After decades of Wisconsin weather, the concrete around this Black Creek home—including the garage apron, sidewalk, and driveway—had settled and cracked. Slabs were uneven, joints were deteriorating, and the surface was beginning to show signs of water infiltration and erosion. The homeowner wanted to fix it before the damage got worse—and avoid a full replacement.
Our team at Sure-Dry lifted the sunken sections using PolyLevel®, a high-density polyurethane foam that fills voids and raises concrete back to its original position with minimal disruption. We then sealed the cracks and joints using NexusPro®, a flexible, UV-resistant sealant that keeps water and debris out to help prevent future shifting and cracking.
The result? A safer, cleaner-looking, and longer-lasting concrete surface—without the cost and hassle of tearing it all out.

Before: A homeowner in Black Creek, WI, had a sinking concrete slab in their backyard and an uneven walkway leading to the side entrance of their garage. Settlement had created uneven surfaces and potential tripping hazards, making both areas less convenient and safe to use.
After: Sure-Dry used PolyLevel polyurethane foam injection to lift and stabilize the settled concrete without the expense of replacement or the larger injection holes associated with traditional mudjacking. Our crew then applied NexusPro joint and crack sealant to help prevent water from reaching the soil beneath the slabs. The completed repairs improved the appearance and functionality of the backyard slab and garage walkway.
