Galvashield® N anode units should be installed after placement of reinforcing steel. The location and spacing of the units shall be as specified by the designer (refer to design criteria). The units are placed in the center of the reinforcing grid to provide even current distribution to the steel. The minimum concrete cover over the anode units should be 1 in (25mm). Securely fasten the anode units by wrapping the two individual steel tie wires multiple times around the reinforcing steel in opposite directions. Using a rebar tie wire tying tool or pliers, grab the loop ties and twist the anode tie wires tight. Anode-to-steel and steel-to-steel continuity should be verified with an appropriate meter prior to concrete placement. A value between 0 and 1 ohm should be achieved. Discontinuous steel should be tied to continuous bars using steel tie wire and re-tested. For targeted protection along construction (cold) joints, install two lines of Galvashield® N anodes, one on each side of the joint a maximum of 8 in (200mm) away from the joint.
