How does it work?

Once attached to the steel and embedded in concrete, the anodes begin passing a current onto the reinforcing steel. This current will accumulate over time to create a double-layered defense:

1. While the anode is active, it generates alkalinity while repelling chlorides, which creates a buffer zone around the steel.
2. The second defensive layer is made by attracting other ions to fill the voids where corrosion can initiate. These ions stay in place as a residual protective layer even after the anodes are consumed.

The net effect is a significant increase to the steel’s tolerance to chloride, making it theoretically immune to corrosion for decades.
