I have admired the forum from a distance for a while and have today signed up for some advice. 
I've been approached to relay a patio. Everything is solid. 100mm+ compacted hardcore, 30-40mm sand cement bed and then a 30mm grantite with a slurry bond to the back. The Client doesnt like the granite and wants to tile directly over this....Crazy i know!
Presently the tiles are unsealed and ungrouted and they have asked about tiling directly over... there is a sufficient height allowance but I'm a little hesitant given the actual base of this is not solid concrete.
any advice would be gratefully received.... i may go down the route of ripping up but seems such a waste of labour if not needed.
