Ocean Pines Condominium Cathodic Protection

This 10 story, 54-unit condominium was the first of several large upscale oceanfront condominiums in South Florida to have Corrpro’s impressed current cathodic protection (CP) system for corrosion control of the reinforcing steel. CP was installed on all of its balconies. Highland Beach is located between Boca Raton and Delray Beach in Palm Beach County, Florida.

Problem

During 1999 the Owners of Ocean Pines Condominium were preparing for their third major balcony restoration in eight years. They became serious about CP when their long range planning committee realized that the cost of installing the system would be paid for in one-cycle of balcony restoration (5-7 years). The oceanfront exposure for this building allows airborne chlorides (salt) to enter the concrete and find their way to the reinforcing steel, resulting in rapid corrosion. For years the Owners had tried to combat the corrosion problem by patching and applying sealers and membranes to the concrete surface. Unfortunately, these techniques only worked for a short time and before long, the Owners were facing another cycle of concrete repair.

Solution

The Board elected to install ELGARD’s™ titanium mesh anode encased in thin-set mortar under new ceramic tiles for the balcony slabs. Other protected elements included window canopies and supporting columns, however, in these areas, the ELGARD™ ribbon anode was used by installing it in saw cut slots.



Performance

The entire system is powered and controlled by Corrpro’s rectifier and CORD-COM™ remote monitoring system. The system is operating at optimum voltage and current levels to control further corrosion of the reinforcing steel in the concrete balconies, canopies and supporting columns. Corrpro will continue to monitor the CP system remotely from its head office in Medina, Ohio.



Value

The Corrpro CP system puts Ocean Pines at the leading edge of balcony restoration in older condominium buildings. The CP system will eliminate the costly cycle of repairs for 25 years or more. Other major benefits include the elimination of noisy jackhammers, dust, invasion into some units, and the considerable inconvenience of cyclical concrete repair and patching. The Owners now have the technical and economic advantage of not having to face replacement of their entire balconies at 5-10 times the cost of installing a CP system.

Leading governmental and independent trade organizations have monitored, tested, and reported on corrosion control strategies over the past three decades. These groups include the American Concrete Institute, National Association of Corrosion Engineers, and the Federal Highway Administration. They advocate CP as the only rehabilitation technique that effectively stops corrosion in salt-contaminated structures, regardless of the chloride content in the concrete.
