Concrete Zinc Anodes / Galvashield Anodes / Embedded Zinc Anodes

SK INDUSTRIES is the original embedded galvanic anode for concrete repairs. SKI range has been protecting structures around the world. The anode units are alkali-activated with an internal pH of 14 or greater to keep the zinc active over the life of the anode and are non-corrosive to reinforcing steel. Once installed, the zinc anode corrodes preferentially to the adjacent reinforcing steel to provide galvanic corrosion prevention or corrosion control. SKI Anodes are classified as Type 1 Anodes – embedded in concrete repairs. SKI anodes improve the durability of concrete repairs by providing targeted protection where it is needed the most, at the interface between new and old concrete.
