Anhydrite Screed - Builder Nightmare - Which Hygrometer

[McLovin]

If it is keeping you awake at night walk away .its not worth it , I'm not saying never do anything like this just maybe when you've got more experience .

Cheers Pal. Its keeping me up as Im going through all the different options at night. Im 4 years in and have a good rep and customer base. I just want to make sure its been done right.

I don't want to shy away from a problem. How else do yo build your experience.

I know what you mean though.

I’m glad it’s not my job!

Its a dogs dinner.

Any ideas? A soft joint won't be enough but anything else will look terrible. How do people get round this. Extensions being built next to existing substrate is a common thing.

Its also 80 x 80 tiles just to add a bit more of an edge to this job.

I saw that on that thread. I had considered it but can't leave anything to chance on this job.

Totally agree....... Life's to short to be getting stressed about work and not sleeping..

I’m not sure why there is a corse of bricks in the floor still. Is it an option to get the whole floor nice and level, then ditra the whole thing and just put your expansion joint in within the 13m length? Unless it has any ufh in this screed ?

I agree Andy but Id take some stress if its outwieghed by experience and knowledge gained. Knowledge is power as they say.

I have no idea why the bricks have been left in. It makes no sense to me but who knows how a builders mind works.

My plan dependant on moisture test was fill voids in brick work with flexible turbo adhesive then to level the entire floor with Arditex CL. Once dry Dirta over the the entire area. Add an expansion strip where the bricks curve round and use a Silicon joint where there other line of brinks (ones in picture) are. If I am not mistaken Dirta allows a moment of up to 4mm incase there is movement or further shrinkage but a soft joint should help. Lucky an Island sits on a section of brick work.

Sounds too easy?

No UFH.

Make sure you get it sanded first!

Walked away from the job in the end.

There were to many issues with bad prep that were not acceptable.

After a box reading the humidity in the floor was still in the mid 90's. Which I would put down to it not being sanded and moisture not being able to escape.
