Hi, I'm installing a Looploc cover around my pool. The pavers are set in sand and locked in with polysand. Looploc suggests that I use 1" x 15" aluminum tubes that need to be inserted into the pavers and base with a hammer drill. There is an anchor that sits in the top of the tube that holds the straps/springs of the cover. I've talked to a few supply houses that say contractors just drill the anchors into the pavers and don't bother with the tubes. The pool people who sold me the cover and Looploc say that if I don't use the tubes there is a chance the pavers will pull out. I'm thinking that it's a mesh cover and the water will go through it and maybe there might be some ice that freezes on it at best. The pulling will be from the side and not from the top. I've removed a cracked paver before and it was a ***** taking over an hour. I had to crack it to get it out. So the question is should I use the tubes at 6.00 each which will make a larger hole that is more readily seen or the smaller holes just for the anchors. I need to drill about 20 holes at a depth of 16" L x 1" W or should I just drill the smaller anchors and install them into the pavers? I actually bought the tubes anyway but can return them. Thanks in advance.
