Channel in floor

[troweler]

Hi all got a large kitchen/diner to tile in porcelain,36m in total however there is a channel 150mm wide and 50mm deep running through the floor with hot water pipes in it.This will obviously heat that area.Any ideas how to fill it in ? Should i screed it then use a good flexi on that part of the floor?? Ditra? Thanks in advance guys.

Cover the pipes in Denzo tape or similar and then SLC the channel.. weber floor flex does 50mm in one bite...

Once that is done and set, then use a slip membrane over the channel... use Dural wp or similar and over lap around 300mm either side of the channel, this should prevent cracking to tiles.. the best method of course is to fully uncouple the floor but slip membrane does work.
