Concrete Stabilization & Foundation Protection
Challenge
The Manchester, IA property exhibited localized slab settlement adjacent to the residential foundation. This settlement altered the original grading profile, transforming a functional concrete walkway/patio into a catchment area.
During the site evaluation, System Design Specialist Shawn Conaway identified a negative slope gradient pitching directly toward the structure. This configuration allowed stormwater to pool against the foundation wall, significantly increasing hydrostatic pressure and the risk of sub-grade water intrusion.
Solution
To permanently stabilize the concrete and eliminate the drainage hazard, the team deployed a two-part technical solution. First, the sub-grade required deep consolidation using PolyLevel, a high-density, hydro-insensitive polyurethane polymer engineered to expand beneath the slabs, fill hidden subterranean voids, and lift the concrete back to its original elevation. Following the lift, the surface required a permanent moisture barrier to prevent future soil erosion. This was achieved using NexusPro Joint Sealant, a highly flexible, UV-resistant silicone compound designed to seal all cracks and control joints against water infiltration while accommodating ongoing thermal expansion and contraction.
