Galvanic protection systems utilize sacrificial anodes that naturally generate an electrical current to mitigate corrosion of the reinforcing steel. In concrete structures, zinc anodes are typically used. Galvanic protection for concrete can be classified into two categories: targeted protection for concrete repair and distributed systems for blanket protection.

Discrete anodes are used to provide localized protection around concrete patches or places into drilled holes on a grid pattern to provide targeted concrete corrosion control.   Galvashield® XP and Galvashield XP+ embedded zinc anodes are examples of discrete galvanic anodes that are used to provide corrosion mitigation for concrete repair.  Galvashield CC zinc anodes are installed into chloride contaminated concrete, carbonated concrete or areas with high corrosion potentials to achieve corrosion control in targeted areas of concrete structures.
