Concrete Repair in Dubuque, IA
Challenge
The homeowners of this Dubuque property noticed their front walkway was no longer level. Over time, soil erosion and settling had caused the heavy concrete slabs to sink, creating uneven "lips" between the sections. What began as a minor aesthetic issue had evolved into a significant tripping hazard for guests and delivery drivers.
The owners needed a solution that was faster and more cost-effective than tearing out the existing concrete and pouring a new path.
Sales Consultant Rob Chismark arrived to evaluate the site. He determined that while the concrete itself was in good structural shape, the subgrade beneath it had washed away, leaving voids that offered no support.
Rob proposed a two-step "Lift and Seal" strategy:
PolyLevel® to fill the voids and lift the slabs back to their original height.
NexusPro® to protect the work from future water damage.
Solution
Foreman Justin Maddox and his installation crew took over the site to bring Rob’s plan to life. The process was minimally invasive and remarkably efficient:
Slab Stabilization: Justin drilled small, penny-sized holes into the sunken slabs. He then injected PolyLevel®, a high-density polyurethane foam. As the foam expanded, it filled the empty pockets under the walkway and provided the precise upward pressure needed to level the surfaces.
Joint Protection: Once the walkway was perfectly aligned, the team addressed the gaps. Justin applied NexusPro® Joint Sealant, a professional-grade silicone-based sealer. Unlike traditional caulk, NexusPro® remains flexible and won't crack under extreme Iowa temperature swings, ensuring the joints remain watertight for years to come.
The transformation was immediate. By the time Justin and his team finished, the walkway was once again a smooth, seamless transition from the driveway to the front door.
The homeowners were thrilled to avoid the mess of a construction zone. Thanks to the expertise of Rob Chismark and the technical skill of Justin Maddox, this Dubuque home didn't just get a repair—it got a permanent upgrade in both safety and curb appeal.
