Ray’s Splash Planet in Charlotte, NC was built circa 2001 as an indoor waterpark. The ‘Blue Comet’ is a 3-story waterslide that serves as a main attraction to the waterpark. It is accessed by a 21 ft tall conventionally reinforced concrete stair tower with three intermediate landings and one top landing supported by reinforced concrete columns. Chloride contamination and reinforcing steel corrosion was identified requiring substantial structural repair and cathodic protection to extend service-life. Shoring was required due to extensive distress where a column tied into a landing. A hybrid cathodic protection system relatively new to the United States was employed that uses both an initial impressed current phase powered by batteries to passivate steel and sustained long-term galvanic phase relying on zinc anodes to maintain passivation. Meticulous protection of the waterpark and pool areas was needed, requiring special staging and care. Tight schedule, discontinuities in the reinforcing steel, need for use of external DC powered batteries instead of hard-wired AC current supplies, clever routing of cathodic protection conduit and wires to alleviate any potential perception concerns, and variability in concrete resistivity were examples of challenges. Replacement of deficient carbon steel guard anchors with stainless steel was also included.
