THE PATCHGUARD™ GALVANIC ANODE - unique corrosion repair solution

PatchGuard™ galvanic anode is located within the parent concrete. Protective current is delivered directly to the steel outside the patch which is at greater corrosion risk as opposed to clean steel within the patch repair. The unique anode design permits use of high resistivity repair material and bonding primers.

THE DUOGUARD™ HYBRID ANODE™ halts reinforced concrete corrosion

DuoGuard™ hybrid anode™ system halts steel corrosion within seven days. The application of the 7 day high current density treatment has the effect of halting corrosion activity on the reinforcing steel surface. This is achieved by moving corrosion to the installed anodes whilst changing the environment at the steel to passive conditions.
