Concrete Repair in Muscatine, IA
Challenge
When a homeowner in Muscatine, IA, contacted us regarding a severely settled front walkway, the primary concern was the immediate liability posed by a two-inch vertical offset at the primary entrance. This case study examines the restoration of structural integrity and pedestrian safety through the application of advanced geotechnical polymers.
The initial site assessment, conducted by our system design specialist, revealed that the concrete failure was not merely superficial. Sub-slab erosion, likely exacerbated by poor drainage and seasonal soil contraction, had created significant subterranean voids. These gaps left the heavy concrete slabs unsupported, leading to differential settlement and the formation of hazardous cracks that invited further water infiltration.
Solution
Our restoration strategy utilized the PolyLevel system, a high-density, closed-cell polyurethane foam. The technical team drilled a series of 5/8-inch ports into the affected sections to allow for targeted injection. Upon introduction, the liquid polymer underwent a rapid exothermic reaction, expanding to fill every void and compacting the underlying soil. This controlled expansion generated sufficient lift to return the slabs to their original grade with millimeter precision, eliminating the trip hazard without the need for a full demolition and repour.
To ensure the longevity of the lift, we addressed the root cause of future erosion by installing NexusPro joint sealant. This medical-grade silicone is engineered to maintain flexibility through Iowa's extreme temperature fluctuations, preventing surface water from reaching the subgrade. Unlike standard organic sealants, this material is highly resistant to UV degradation and chemical exposure, ensuring the joints remain watertight for the lifespan of the concrete.
The completed project restored full functionality to the home's entrance, providing a level, stabilized surface that meets all modern safety standards. By integrating structural lifting with comprehensive moisture protection, MidAmerica Basement Systems provided a long-term engineering solution that successfully mitigated the homeowner's liability and preserved the property's structural value.
