Galvanic Protection

Sika® FerroGard®-650

Sika® FerroGard®-650 is a zinc based discrete sacrificial anode placed inside a concrete repair area in reinforced concrete structures which are corroding as a result of chloride induced corrosion.

Sika® FerroGard®-650 anodes are placed along the perimeter of the repair area and fixed to the reinforcement prior to the application of a concrete repair system. The reinforcement outside the repaired area is at greatest corrosion risk owing to the passive condition of the reinforcement within the repaired area. Sika® FerroGard®-650 anodes corrode preferentially to the surrounding reinforcement offering protection against incipient corrosion damage.
