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
