Hi! We recently revamped the 12 year old pool in the backyard of the house we bought 3 years ago, including plumbing repair, liner replacement, conversion to salt water, and replacement of the aggregate concrete deck (which we had to tear up to fix the plumbing) with a tiled flagstone deck. In our area, the pool builders with experience laying stone decks were more high-end and therefore not interested/experienced with vinyl pools, and so we ended up going with a highly recommended vinyl pool builder with little stone experience, and having him do all the liner/repair work and laying the concrete base for the deck, and then bringing in an experienced stone guy to lay the flagstone tile on top.
The pool came with an Anchor safety mesh cover, and now we'd like to set anchors so that we can use it when we close the pool this fall. During construction, some of the guys on the stone crew said that they should do it, so that they would be around to replace any tiles that cracked during drilling and placement, and since our PB doesn't have much experience working with stone, using him seems like a disaster waiting to happen But, I believe this is the first pool deck the stone crew has done; they are more experienced with patios, etc, so they haven't set anchors before and NONE of us are interested in screwing up the $$$ stone we just laid. The stone guy seems a little hesitant since he is inexperienced with this task and I told him I would find out what I could. The folks at Anchor covers were totally useless when I called for their advice, so I thought I'd turn here.
The stone is square and rectangular Pennsylvania bluestone, average thickness 1.5", on top of a ~ 1" base of mud, and mortared in between, all set on top of a solid concrete base. Will it be sufficient to drill into the stone and set the anchors there? Do they need to be epoxied? Do we need to use the 9" metal sleeves recommended for unmortared flagstone (I did read one horror story in this case on this forum) or will the mud and stone be enough to hold it down? It is an approx 18'x35' Grecian pool with a total of 41 anchor points. I am in Northwest Arkansas, if that is relevant.
Thanks for any advice! We're first time pool owners so I have learned a lot from this forum!
