Slightly different application but ... at the airport we are working (okay I'm working) on the renovation of our parking garage (it's approximately 35 years old). As with any renovation project, when you open up something (could be anything, a delaminated parking slab, a column that had concrete that was showing some sort of problem, etc) you often find more than you bargained for. In this case we have some corbels on some columns which support some bridges that go from a helix (the concrete structure which cars are able to circle in an upward motion to reach the various levels of the parking garage) to the parking garage itself (where there are opposite corbels to hold the other side of the bridge). Some of these corbels have been shown to be weaker and/or lacking in the strength needed to support the bridge and the cars (makes you wonder about the last 35 years). Anyway, on those questionable corbels we have been wrapping the corbels with the carbon fiber wrap, all per the consulting engineer. Again, this application is certainly different than yours, but in my own way I can relate.
