When and Where Ditra Questions ?

[2020Tiling]

Hi, Iam not sure and when and what tile to use ditra with if iam honest , and would like some Advice please. I know how ditra works but unsure exactly what tile / Substrate to use it with ? I would use it on wood with any stone tiles , but I have a 27mtrs Concrete floor to do and unsure if ditra is needed. the floor is Origional Conrete with no cracks and in good condition and has no moisture/damp issues. and no UFH. the Customer is unsure if he wants Travertine , Porcelain or Ceramic tiles , and Iam unsure if ditra is needed with it being Concrete? i know trav is brittle and more likely to crack so i would use ditra it with trav , but unsure about using it with Porclain or Ceramics ?

No ufh, no damp and old good quality concrete all adds up to no likely excessive horizontal movement so in this case i would say ditra is not necessary.

To be honest, most of the time it will come down to cost and if the customer is willing to pay for it as it will not do any harm to use ditra on any floor but as Ajax has said, I wouldn't have thought that the is floor NEEDS it.

Thanks for your replys ! I dont want any more floors to fail due to me not doing things the Tilers Forum way (The Correct way). Ive had one floor failure in my time so far and it was a nightmare to put right not to mention the Embarrassment. having said that it was on a ply floor !
