Concrete Repair in Rock Island, IL
Challenge
The property in Rock Island presented with significant differential settlement across several exterior concrete sections, including the primary walkway and driveway approach. Upon inspection by System Design Specialist Rob Chismark, the root cause was identified as sub-grade soil erosion and compaction failure.
The resulting "tripping zones" were not merely aesthetic issues; the slabs had shifted out of alignment by several inches, creating hazardous vertical offsets (lippage) and allowing moisture to infiltrate the sub-base, which threatened to accelerate further subsidence.
Solution
The technical intervention successfully restored the structural integrity of the concrete surfaces. The application of PolyLevel® provided immediate load-bearing capacity, allowing the homeowner to utilize the driveway and walkways within 15 to 30 minutes of completion.
Key Technical Outcomes:
- Permanent Stabilization: Voids were fully remediated with non-biodegradable foam.
- Precision Alignment: Vertical offsets were reduced to within 1/8" of the original design specifications.
- Moisture Mitigation: NexusPro® application redirected surface runoff away from the sub-grade, significantly extending the life cycle of the concrete.
