The following slides reveal typical corrosion failures which the HRCSA chemistry was purposely created to chemically stop. <30+ years field performance history>
Begin with the end in mind – lending an ear to your structure’s aches and pains.
When moving away from “How this is normally done.” toward taking a step back and asking yourself: “What outcome do I want from the refurbishment investment I am about to make?” can have a positive impact when you know what you’re looking for. The following example highlights an owner trying out such an approach. An approach that produced savings of:
AHBA Newsletter, “A third environmental improvement is a change in a coating we use on the bridge… (HRCSA)… this replaces the less environmentally-friendly zinc-rich system used previously… ” Aukland Harbor Bridge “In 1998, Tansit NZ introducd the system of PERFORMANCE SPECIFIED MAINTENANCE CONTRACTS (PSMC). This was based on a long-term performance specification under which the Contractor is required to ensure that the overall condition and level of service of the asset is maintained to a pre-determined standard.”
“… Therefore, in addition to cost and environmental impact, minimizing the containment requirements is one of the main criteria when selecting a maintenance strategy.”
HRCSA: Corrosion Mitigation Performance.
In addition to being able to reduce containment costs and lower environmental impact, HRCSA also offers unique ways to chemically stop active structure critical corrosion. This slide demonstrates a few other performance enhancements you can expect from the HRCSA corrosion mitigation coating system.
