Hi
As a competent DIYer Im building an extension and installing wet underfloor heating. The area is 60m2 plus 20m2 (separate rooms) and I wondered if you experienced tilers could help with some advice to make sure I get it right? The floor will be a structural slab (100mm) with 110mm insulation on top and then screed over the pipework. I will put in expansion joints (structural and screed) and would expect a minimum of 5mm expansion of each slab even without hetaing it up (the larger area will be split 60/40) but dont know how to accommodate movement over the joint with tiles. I would use the flexible adhesive but dont know which grout to use or whether I need to put an expansion joint between the tiles where they overlay the concrete expansion joint (probably foam). Any help appreciated?
