Concrete Repair Photo Album: Restoring Peace of Mind: Supporting a Sinking Pool Deck in Monticello, FL

When this homeowner reached out to us about their pool deck, the surface damage only told part of the story. A few visible cracks and uneven slabs seemed like a minor cosmetic issue on top, but a closer inspection revealed a much larger problem underneath: erosion had washed away the supporting soil, leaving massive hidden voids beneath the heavy concrete. Left unaddressed, those empty spaces were a ticking clock for structural failure, risking major damage to both the deck and the pool structure itself. Rather than tearing up the entire backyard with heavy machinery, high costs, and weeks of disruption, we brought in a far less invasive, long-term solution: PolyLevel® high-density polyurethane injection. Our team started by drilling tiny, penny-sized ports directly through the affected slabs. Through these ports, we injected a two-part high-density polymer into the empty cavities below. As the foam reacted, it expanded rapidly, filling every nook and cranny of the void and packing the loose soil tight. Once the space was completely filled, the controlled expansion gently lifted the sunken concrete back to a flush, level finish. The entire process wrapped up in a matter of hours, and because PolyLevel® cures in just 15 minutes, the homeowners were able to use their pool area the very same day. Even better? The waterproof foam won’t wash away, rot, or degrade over time, permanently sealing out moisture and stabilizing the foundation for years to come.
