Galvanic anodes redress the electrochemical imbalance induced through removal of contaminated concrete in patch repairs. PatchGuard™ anodes corrode preferentially to the surrounding steel protecting it from further corrosion damage.
HOW DOES IT WORK?
Rather than the traditional approach of attaching galvanic anodes to exposed steel in the patch repair, PatchGuard anodes are located within the surrounding unrepaired concrete. Protective current is delivered directly to the steel outside the patch repair which is at greatest corrosion risk as opposed to the clean steel within the patch repair.
As PatchGuard is installed in unrepaired concrete, there is no compromise in the quality of the concrete repair material used in reinstatement, as is typically the case for sacrificial anodes placed within patch repairs.
