For those of you that have spas attached to the pool, do you have an isolation joint around the spa too where it comes in contact with the deck? The builder placed the foam around the perimeter of my pool separating the coping from the concrete deck but did not continue the foam barrier around the stack stone of the spa. So the concrete was poured up to the stack stone of the spa, actually same thing as my firepit. I know this is not correct, thanks Bdavis, but I just wanted to get some feedback from others on this situation. Since I am going to need to pull up a lot of my new deck I might as well do it in these areas also if I am going to run into problems.
