Before:
Sections of sidewalk west of the stop sign—across from the Wok Box entrance—had developed severe trip hazards and catastrophic fractures, spanning up to 32 linear feet. The lack of reinforcing steel meant slabs were vulnerable to movement and failure, with tripping points forming at the curb and relief cuts. Prior to repair, the client barricaded the adjacent parking lot for crew access and safety.
Project Solution:
To control slab movement during lifting, our crew temporarily installed purpose-built “limit lift bars” to prevent over-elevation and protect non-reinforced concrete. We injected our proprietary, climate-engineered polyurethane foam beneath the affected slabs for maximum compressive strength and permanent sub-base bonding.
As the foam expanded, it filled voids and adhered to both aggregates and slab undersides. This process stabilized the sidewalk, minimized surface cracking, and dramatically reduced ongoing trip hazards. The finished product: a level, durable walking surface able to withstand daily commercial use and Manitoba freeze/thaw cycles.
Results:
- Trip hazards eliminated and walk surface restored
- Catastrophic fracture risk mitigated
- Slab stabilized with proprietary foam and limit lift bars
- Future crack formation minimized for long-term durability
- Commercial pedestrian safety and curb appeal enhanced
