a little help with a merlin cover install on paver deck
I'm getting ready to install a travertine paver deck around our gunite pool. I have a Merlin cover, it came with the 15" tubes to drive into to subgrade. A neighbor happes to be having a vinyl pool installed now, and I was talking to their project manager. He recommended placing a 1 foot wide ribbon of concrete, 4 inched thick or so, all around the circumferenct of the pool where the cover anchors would be. Then after I core drill the travertine, I would use a hammer drill to get through the concrete. This would provide a solid substrate for the anchors, and take lateral stress off of the deck.
Is this necessary, or overkill? I could see the benefit for a vinyl pool, but for gunite, I'm not sure.
