Galvanic Corrosion Protection of Reinforced Concrete Structures, Ball & Whitmore

In the past 10 years, there have been significant advancements in galvanic anode technology for reinforced concrete structures. Today, galvanic protection is the most commonly utilized form of corrosion protection for reinforced concrete in North America. The popularity of galvanic systems is due to many factors including ease of installation and little or no on-going system maintenance costs.

Distributed galvanic anode systems are used to provide targeted protection to specific structural elements as well as global protection to large areas in both marine and non-marine exposure environments. Examples of distributed galvanic protection technology include humectant-activated arc spray zinc and galvanic jacketing systems

Recent installations for distributed anode systems include a multi-million dollar rehabilitation of four cargo loading piers at Cape Canaveral, Florida. This project utilized a range of galvanic protection systems targeted to the varying needs of the structure. Distributed protection was utilized to protect over 5,000 m2 of prestressed concrete decks and 668 prestressed concrete piles in saltwater.  (read more)
