    Did very similar in daughter's place. Blackjacked floor going up wall a tad to make sure no weak point for moisture entry, found highest point to level from then drilled and screwed down CLS flat (84x36) levelling with plastic shims and a good splurge of sili to seal round screws. 30/35 Celotex between. 18 ply all screwed down. Daughter insisted on really big tiles (agin my advice) but all rock solid and no cracks after 4 years.
