Sika® FerroGard®-650

DISCRETE EMBEDDED GALVANIC ANODE

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. Sika® FerroGard®-650 can also be placed at specific positions on steel reinforcement stirrups when used in new construction to prevent corrosion in marine environments. Suitable to use in hot and tropical climatic conditions.
