I have a in ground pool. The sides are fiberglass and the bottom is concrete. I have leaks at the joints between the 2. My pool company tells me I’m out of luck. What’s the best fix for this? What can I do to stop the incoming water. I know if I fill it after painting the the pressure might even out and it will be ok, but I have to much time and money to not get these leaks fixed before painting the bottom concrete! I live in the north east and need to get this fixed asap! Thanks for your help!
