Sika® FerroGard®-520 Patch 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 or carbonation.
Sika® FerroGard®-520 Patch anodes corrode preferentially to the surrounding reinforcement offering protection against incipient corrosion damage. In addition, standard repair mortars, bonding primers and reinforcement corrosion protection coatings can be used as Sika® FerroGard®-520 Patch is placed in the parent concrete and not within the repair mortar.
Advantages
- Sika® FerroGard®-520 Patch anodes corrode preferentially to the surrounding reinforcement, protecting it from further corrosion damage
- Protects against incipient anode effect outside of repaired area
- No long term maintenance costs
- Strengthens passive film on reinforcement
- No rapid dissolution of activating components
- Quick installation—no additional concrete break out
- Bonding primers for concrete and reinforcement corrosion protection coatings can be used
- High resistivity repair mortars can be used
- Performance can be monitored
- Cost effective corrosion control solution
Where to use
- Controlling the incipient anode effect by electrically balancing the anodic and cathodic areas of reinforcement
- Targeted treatment applied to concrete repaired areas to prevent incipient corrosion damage
- For reinforced concrete structures such as bridges, car parks, coastal structures, industrial structures and residential high rise
- Coastal reinforced concrete structures both in and above the tidal zone
