I've sorted it now, i told him politely to get back the builder who laid the screed to lay the tiles as i wasn't prepared to lay them until the UFH had been running for at least a week, the customer insists that the floor is now ready for the tiles (it,s only been down for 3 weeks) where as i told him i would come back at the end of february, (26th) i also told him not toring me back in 6 months time when the tiles will have cracked. Thanks lads for all the replies it makes my choice feel that much easier.This job is not going to end well if you stick the stone to this screed after only 6 weeks with no ufh commissioning and no uncoupling.
I would insist on commissioning the ufh, then fit durabase mat or ditra to control the moisture which is left
