PROBLEM
Winters in Toronto are harsh due to extremely low temperatures and heavy snowfalls. Using de-icing salt during this time is a standard practice in Ontario, despite the destructive impact on concrete structures. Parking garages are especially prone to corrosion from the amount of water and salt carried into them by vehicles. This destructive effect is compounded both by CO2 emissions from vehicle exhaust and by water pooling on concrete due to poor drainage. Over the years, these factors led to the deterioration of the first level concrete slab of the Buckingham Court condo underground parking garage (built-in 1954), and the building owner had to address the problem.
APPLICATION
The engineer assigned for the job had done several jobs using Cortec’s MCI®-2020 with great success in controlling corrosion activities and slowing down corrosion rates. This led the engineer to specify MCI®-2020 for application to the whole slab on level T1. The slab was first cleaned and prepared mechanically before applying two coats of MCI®-2020 by a roller at a coverage rate of 150 ft2 /gallon (3.68 m²/L). A waterproofing membrane system was applied on top 24 hours after MCI®-2020 application.
CONCLUSION
The contractor was happy with the ease of application and with the technical support offered by Cortec® during the different stages of the job.
