VCS designed and provided installation QC testing services for replacement of an existing wire slot impressed current cathodic protection system to protect a concrete parking ramp.
The Macy’s parking structure was undergoing repairs. The facility manager and contractor requested VCS to evaluate the condition of a 20-year old slotted wire anode system. VCS determined some zones of the system had ceased to function due to broken wires and failed grout in the slots, while other zones appeared to be partially operational. The facility manager wanted the system replaced as part of the existing repair program.
VCS Engineering performed a durability assessment using industry-recognized methods — including visual inspections, material sampling, and resistivity studies — to understand the condition of the existing cathodic protection system. Based on those insights, a new ribbon-anode protection design was developed to suit the existing concrete properties and structural layout. Quality oversight during installation helped ensure the updated system meets expected performance and longevity standards.
