I just temporarily repaired a hernia in the sidewall of our 20+ year old pool. There is other evidence of rust as well, mostly at the bottom. It's a 16X32 with a deck all the way around it. My first thought was to replace the pool this winter. But 16X32 seems to be an obsolete size. So replacing the pool requires a major rebuild of the deck.
My next thought is to reinforce the walls with galvanized sheet metal 2' wide, partially draining the pool and slipping the metal between the posts and the wall. Since the idea is to prevent hernias, there shouldn't be any force that would push the new metal from out of the posts.
If that isn't advisable...any recommendations on a brand for a new pool?
