A customer has an outdoor BBQ/Bar made out of concrete with brick over it and tile counters. There are 4-5 1 and 2 gang aluminum bell boxes (WP) embedded/grouted in the brick with sch 40 PVC going into them. Well, they are all corroding inside (near a pool), to the point that the aluminum is disolving into powder and the screws don't stay into the steel plates due to rust, etc. Customer (and myself!) would like to replace these with a longer lasting setup.
Do you guys have any ideas on how to extract these old boxes out, put something new in, and connect the PVC to them? I am at a loss on what to do. I will probably have to get the grout re-done. Oh yeah, money is not much of a problem, he wants it done right, so is there an industrial product or something esoteric I'm missing? Any creative ideas would be excellent. I really don't want to have to rip up a ton of brick and concrete just to replace these boxes. Shame on the original guy for using aluminum in concrete!
Thanks for any help, Mike
