    Pool deck separation from tile

    Our '96 pool is exhibiting similar issues to this post http://www.troublefreepool.com/threa...astic-and-tile

    Unfortunately, I think ours is a little further along. There was a leaky sprinkler that I repaired on the other side of the pool deck right across from the widest separation (see the second photo). I'm thinking that was the main cause of the issue. Now I'm wondering what would be a good fix on the pool side to fill that gap. A fiberglass rod will go back about 12" before I hit something solid.

    -foam backer rod with silicone caulk over it?
    -expanding foam further back in to provide support then the backer rod and silicone?

    Thoughts?

    I'll try to attach photos. (I know the tile needs cleaning and the lawn needs to be mowed too.)

    I would try backer rod and polyurethane caulk. How wide is that gap?

    There's a process called slab jacking that might be a good solution for you. Holes are drilled into the concrete (about 3/4" diameter) and then grout is pumped through the holes to hydraulically lift the deck back to level.

    the widest part of the gap is ~ 1/2"

    I had thought of the slab jacking but thought maybe a DIY fix first?

    how long has it been since you fixed the leak? Might want to give it some time to see if it settles back down after it dries out.
