Sika FerroGard-720 Reba Galvanic Anode
Sika FerroGard-720 Reba is a zinc based discrete sacrificial anode placed inside a concrete repaired area in reinforced concrete structures which are corroding as a result of chloride ingress. Sika FerroGard-720 Reba anodes are placed along the perimeter of the repair area and fixed to the reinforcement prior the application of a concrete repair system. The reinforcement outside the repaired area is at greatest risk owing to the passive condi
- Sika FerroGard-720 Reba anodes corrode preferen-tially to the surrounding reinforcement
- Protection against incipient anode effect outside of repaired areas
- No long term maintenance cost
- Strengthens passive film on reinforcement
- No rapid dissolution of activating components
