We passed bonding inspection in which the bonding wire had to be 4 to 6 inches below grade. In addition, one of the bonding wires ran underground to the equipment pad. Since then we have started to build a grotto and slide and the contractor poured concrete behind the grotto to support the slide and the grotto rocks. When they poured the concrete it went over the pipes and the bonding wire. If we ever have to access those pipes it will obviously be a problem, but my concern now is whether concrete over the copper bonding wire somehow affects the bonding potential of the wire?
I appreciate any responses.
