thank you all for your welcome advice. the job is finished now and does look good but we have decided to wait untill the ufh is wired in and tested properly before we hand any money over. i have tested the tiles with a coin and can only just pick out a couple of places where there is a different sound and even then its not horribly hollow sounding. before they tiled they laid a slc over the mat and let it dry before they started tiling. i realy hope that it all works. i will let u all know when i have tested it fully. thanks again everyone. steve.
