I had a travertine paver patio installed and ended up with a large amount of left over pavers. They are sitting in my garage. I'm thinking of laying the extra pavers in the garage (there are plenty to cover the entire floor). For the patio we sand set the pavers. The garage floor is concrete and I believe I could mortar the pavers but I'm not sure I want to. Would it be possible to sand set the pavers over the concrete floor? Would there be drainage issues? Obviously, the garage is enclosed so I don't imagine large amounts of water would ever get in but you never know. I don't imagine that anyone has done this before but was hoping to get thoughts and opinions. Thanks.
