I’m new to being a pool owner and have some questions on my coping stones. I have a 13 year old pool and raised spa in Maryland at my house I bought last year so I’ve only been through 1 pool season. I noticed the flagstone coping stones are loose and there is missing grout between some stones. They are not so loose they wobble significantly, but they have a hollow sound and the grout is coming loose. The pool and raised spa both have this issue.
What is the best way to re-set the stones? I would have thought mortar, but that only lasted 13 years which is not impressive. Should I use adhesive instead?
I also noticed there is no expansion joint between the coping stones and the paver pool deck. I assume I should add one when I re-set the coping stones? The lack of expansion joint probably caused the pool stones to come loose, but I’m not sure why the raised spa coping stones came loose as well. They cap the raised spa wall so they do not touch the pool deck.
Thanks in advance for the help!
