Can the AccoustiCORK RC500 underlayment be used underneath the 8mm Strong Rubber Tiles-Designer Series? I have an unfinished basement room I'm planning to turn into a home gym/theater room�currently a concrete slab. I was thinking of using DriCor subfloor membrane panels over the concrete, then Accousticork over the plywood panels finished off with the 8mm Strong Rubber Tiles. Does this make sense?
