Pool Deck and Shed Concrete Repair & Leveling in Manilla, ON
Challenge
In Manilla, ON, the outdoor living area of this property was compromised by uneven concrete slabs linking the pool deck to the equipment shed. Over time, natural ground movement and soil settlement created voids beneath the slabs, resulting in uneven elevations, sloping surfaces, and unstable transitions. The primary concern was the main walkway, where a slab had recessed significantly, forming a dangerous ledge in a high-traffic area.
These conditions not only posed a safety hazard for daily use but also increased the risk of slab cracking, accelerated wear on concrete edges, and potential long-term soil instability. Addressing the problem required more than surface-level patching; the sub-grade beneath the concrete had to be stabilized to prevent further settling and ensure long-term durability.
Solution
Canadian Concrete Leveling executed a precision concrete lifting and sub-grade stabilization procedure using a controlled polymer injection system. High-density, slow-reacting polyurethane was injected into the voids beneath the sunken slabs, allowing the material to expand gradually and consolidate the underlying soil. This method ensures the load-bearing capacity of the sub-grade is enhanced while minimizing the risk of slab heaving or over-lifting.
Sections adjacent to the shed were carefully aligned to create a flush transition, while the recessed walkway slab was precisely raised to eliminate the tripping hazard. The polymer’s low-viscosity flow allowed it to permeate micro-voids beneath the slabs, forming a dense, waterproof support structure that cradled the concrete from below.
The technical results were immediate and verifiable. Slab movement was fully eliminated, and the backyard now features level, load-bearing surfaces capable of supporting pedestrian traffic and equipment without risk of further settlement. The project was completed with minimal disruption to the property, preserving the original concrete, and achieving a permanent solution in a single afternoon. By stabilizing the sub-grade and lifting the slabs precisely, the system mitigated long-term structural risk and restored safe, functional connectivity between the pool deck and shed.
This project highlights the efficacy of polymer injection technology for backyard concrete leveling, demonstrating how precision engineering and controlled sub-grade reinforcement can solve complex settlement issues safely, efficiently, and cost-effectively.
