RESIDENTIAL CONCRETE RESTORATION

Residential concrete restoration—whether addressing structural columns, underground parking slabs, or exterior building envelopes—is a critical investment in your property's longevity and safety. However, executing these essential structural repairs should never come at the expense of tenant satisfaction. At Concurb Concrete, we approach complex concrete rehabilitations with a deep understanding of both advanced materials engineering and tenant relations. We expertly navigate the requirements of the Ontario Residential Tenancies Act (RTA)—specifically balancing a landlord’s obligation to maintain the premises in a good state of repair (Section 20) while strictly safeguarding the tenants' right to reasonable enjoyment of their living space (Section 22). Our highly phased, strategic methodology ensures minimal impact on the day-to-day usage of the property.

This tenant-first, safety-driven approach is perfectly exemplified in our recently completed full-scale balcony restoration project. By applying our rigorous concrete repair standards, we delivered structurally flawless, OBC-compliant balconies three days ahead of schedule, resulting in absolutely zero unplanned property downtime, zero injuries, and zero near misses.

Phase 1: Independent Structural Assessment & Engineering Collaboration

Before a single tool was lifted on site, an independent, third-party structural engineering firm conducted a thorough diagnostic assessment of the existing balconies. Their comprehensive inspection identified extensive concrete spalling and exposed, highly corroded reinforcing steel (rebar) that had compromised the structural integrity of the slabs.

OBC Compliance: All structural assessments and subsequent repair specifications were engineered by the third-party firm in strict accordance with OBC Division B, Part 4 (Structural Design). This guaranteed that the prescribed repairs would allow the structures to safely withstand all required live and dead loads.
Action Plan: Working strictly off the engineer's approved specifications, our team developed a highly phased restoration and execution plan. This strategy was meticulously designed to isolate construction zones, minimizing disruption to residents and strictly preventing any unplanned property downtime.

Phase 2: Site Preparation and Strict Safety Protocols

Safety is the cornerstone of our operations. Given the high-elevation nature of structural balcony work, site preparation required meticulous attention to detail and proactive risk management.

Safety Implementation: We strictly adhered to the Occupational Health and Safety Act (OHSA). This included mandatory daily tailgate meetings, rigorous fall-arrest training for all crew members, and the installation of engineered temporary shoring and highly secure debris netting.
The Result: Thanks to our proactive safety management and continuous hazard assessments, the project concluded with an impeccable safety record—absolutely no injuries and zero near misses occurred on site.

Phase 3: Demolition and Concrete Removal

Precision is key when dealing with inhabited structures. We utilized specialized, low-vibration chipping hammers to carefully remove deteriorated and delaminated concrete. This ensured we did not damage the underlying healthy structural slab or cause undue noise distress to the tenants working or relaxing inside.

Rebar Preparation: Once the compromised concrete was removed, the exposed rebar was mechanically cleaned to a near-white metal finish to remove all oxidation. It was then treated with an advanced anti-corrosion zinc-rich coating to halt further decay and prevent future rust.

Phase 4: Structural Concrete Placement

Restoring the structural integrity of the balcony slab required precise concrete pouring, consolidation, and curing.

OBC Compliance: All concrete materials and placement methods adhered strictly to CSA A23.1/A23.2 standards, as heavily referenced by the Ontario Building Code for concrete materials and methods of construction.
Application: We utilized high-strength, polymer-modified repair mortars designed specifically for severe structural patching. The concrete was then expertly finished and sloped to ensure proper, positive drainage away from the building envelope.

Phase 5: Final Inspection, Cleanup, and Handover

Following a final, multi-point internal quality assurance inspection of the cured concrete, we conducted a comprehensive walkthrough with the client and municipal building inspectors. The site was thoroughly cleaned, returning the property to a pristine state.

The Ultimate Success: Because of our optimized workflow, advanced curing materials, and dedicated project management, we handed the structurally restored balconies back to the property owner 3 full days ahead of our contracted schedule. The property remained fully operational throughout the entire process, resulting in zero unplanned downtime for the owner or the tenants.

A Commitment to Excellence

At Concurb Concrete, our commitment to excellence goes beyond merely pouring concrete; it is built on a foundation of unyielding safety, precise execution, and absolute integrity. We recognize that executing a successful structural rehabilitation requires strict adherence to the approved remediation plan. By following the independent engineer’s specifications without deviation, we ensure every repair meets or exceeds the exact structural demands of the Ontario Building Code. This meticulous attention to detail is matched only by our dedication to uncompromising safety and strict timeline management. By implementing rigorous on-site hazard protocols, we guarantee a secure environment that protects our crew, your property, and your tenants—resulting in our proud record of zero injuries and zero near misses. Ultimately, our proactive project management allows us to hold fast to our schedules, delivering superior, long-lasting structural solutions—like finishing our latest project three days early—while ensuring absolutely zero unplanned downtime for your community.
