Concrete Repair in Davenport, IA
Challenge
The Chapman family of Davenport, IA, noticed their concrete driveway was becoming increasingly dangerous. Over time, several slabs had settled unevenly, creating "sneaky hills" and significant trip hazards.
In the Quad Cities region, this is a common issue caused by expansive clay-rich soils. When these soils saturate during heavy Iowa rains, they soften and expand; during dry spells, they shrink, leaving behind hollow voids. These voids, coupled with the weight of vehicles, cause concrete slabs to crack and sink, leading to:
Safety Risks: High-profile trip hazards for family and guests.
Liability Concerns: Potential for injury on the property.
Solution
The crew drilled small, penny-sized holes into the sunken slabs. Justin then injected PolyLevel®, a high-density polyurethane foam.How it works: The foam expands into the underground voids, compacting the loose soil and exerting enough pressure to lift the slabs back to their original level.
Within 15 minutes of injection, the foam reached 90% of its full strength, allowing the driveway to be ready for vehicle traffic almost immediately.
Environmental Protection with NexusPro®To prevent the cycle of soil washout from starting again, the team cleaned out the joints and applied NexusPro® sealant.
This UV-resistant silicone sealant is designed to withstand Iowa's extreme "freeze-thaw" cycles without cracking or bubbling.Result: By sealing the cracks, the team "buttoned up" the driveway, preventing water from reaching the soil and ensuring the new lift stays permanent.
