Recently installed outdoor porcelain tiles (Quarziti 2.0) over a gravel/sand base using sand instead of grout between the tiles; and several of the tiles have a crunching sound when walking on them. Have tapped them all in and put weight on them, but some just still making noise. Does this work itself out or do i need to reinstall (perhaps thicker base?).
Thanks In Advance!
