i have a conservatory floor which is 33 sq mts in a L shape
It had a level screed over the pipes and was. very flat as laid with a laser, backed up by tiler who said it was within 1mm all over.

I used a proffesional tiler and was laid with mapei? Both tile and grout cement.
The floor was laid in 2017 and after a year the tiles started cracking by both doors, a double set each end.
Then last end of 2018 we got a couple of cracks in the middle across about 4 tiles.
There’s no difference in height or it’s less than 1mm, it’s like the surface has cracked so I don’t know if it’s expansion or heave.

Floor is 4” polystyreneslabs pipes laid on top, screed I can’t remember but was the standard required for that type of floor. 07DD712C-86B6-49A5-B62A-622B93423A1B.jpeg
