Stress fracture concrete 2 joining rooms ditra?

[Ajax123]

A question with a very relevant but slightly different case,
I have a floor coming up which has small non straight cracks in the concrete which was all pour screeded. Lafarge agilia screed.

Will these cracks cause any problems over time or shall I ditra/schuter the whole floor?
Thanks in advance?

(Floor has underfloor heating, been laid in situ for 3 years)

you need to find out if it's anhydrite or cement. Either way cracks should be repaired following heating being comissioned if you tile direct. However based on the description it sounds like a classic case for ditra

Lafarge agilia screed is cementitious.

Can you guys give me a average price for 50m2 of ditra?

I'll ask my supplier tomorrow.
I have always used Backer board for wooden floors.

This started out as a hairline crack,
View attachment 56386
This was after two years, it cracked the limestone much earlier than this.
The company were advised at the time to go with Ditra but wouldn't listen.

I think I shall have to save this picv stef as an example to future customers
