CP- A balcony's best friend

The Florida coast is a particularly harsh environment for concrete structures, combining heat, humidity and high concentrations of chloride. Concrete balconies in the region are especially susceptible to corrosion of reinforcing steel, requiring major repair and maintenance.

Condo owners recognize that repeating patch maintenance cycles are disruptive and increasingly expensive. However, property managers don't always implement methods for corrosion prevention out of ignorance or because of the cost.

But, applying cathodic protection (CP) can lengthen the lifecycle of the reinforcing steel and concrete, delaying the need for maintenance. CP is a viable long term solution to protect these vulnerable concrete structures, but applying CP to condominium balconies is not easy. The evolution of cathodic protection, as applied to concrete balconies in Florida, has been an evolutionary process. Many systems have been tried with varying degrees of technical and commercial success. In ture Darwinian fashion, some of the solutions took the path to extinction, others evolved and have flourished, and some technologies moved to other, more favorable applications.

Many structural engineers now recognize the benefits of cathodic protection (CP) to stop the corrosion process and how to apply the right system in a given environment. This long-term solution extends the life of these important concrete structures and protects residents who own condos with balconies.

I just hope condo owners and property managers do their due diligence to find out what available technologies will keep residents safe.
