Lasting Solutions for Airport Concrete Surfaces

When Tenera was hired to provide repair specifications for a tenant at Toronto Pearson Airport’s refueling bay, we built on previous work at Pearson and Hamilton International Airport, where we had provided specs for and ensured the completion of apron surface repairs, elevator pit waterproofing, control joint and basin repairs, among others. This time, the tenant required a comprehensive approach to resolve concrete deterioration, cracks, and waterproofing issues.


Key Issues Identified

The refueling bay had several areas in need of repair. Due to significant surface wear, partial demolition of the existing concrete was necessary before new concrete could be poured. The gutter around the bay's perimeter also required restoration. In addition, multiple cracks were found in the surrounding area, and two expansion joints needed to be waterproofed to prevent further water infiltration.


Crack Repair

The cracking present in the concrete surface required a durable solution, and Tenera's specification utilized advanced repair techniques. Unlike traditional methods that fail to address the long-term stability of cracked concrete, we specified a process that essentially fuses the affected slabs. This process restores both single and multiple cracks, even in areas containing embedded metal structures.


The crack repair began with the thorough cleaning of the cracks using either a grinder, saw, or chipping gun, depending on the surface characteristics. Once cleaned, a specialized industrial adhesive was applied to ensure a strong bond and immediate reinforcement of the cracks. This was followed by filling the cracks with a high-performance material designed for long-term durability. This approach ensures not only that the cracks are sealed but also that the integrity of the entire surface is maintained, preventing further deterioration.


Expansion Joint Waterproofing

Waterproofing the expansion joints required a method designed for resilience in high-traffic and environmentally exposed areas. The first step involved cleaning the joints to remove any debris or loose material. After that, an industrial-strength adhesive was applied to the joint to ensure proper bonding. A backer rod was then inserted, fitted tightly to hold the injected waterproofing material in place. The final step was injecting a polyurea-based material that provides flexibility to handle the natural expansion and contraction of the concrete, while also being resistant to environmental factors such as moisture and temperature fluctuations.


Additional Scope of Work

After completing the concrete repairs, the client requested modifications to their VIP parking area. The existing layout of four parking spaces was altered to accommodate eight, with the necessary yellow lines repainted and all parking spaces clearly marked according to the new configuration.


By following these detailed specifications, Tenera was able to ensure that the contractor delivered a lasting, high-quality solution for the tenant at Toronto Pearson Airport, ensuring both structural integrity and waterproofing performance.
