Why FLEXIBLE adhesive / grout?

[zygo]

That makes sense, Dave. I like replies and advice that appeal to my common sense. I might not have mentioned that I laid the dpc and the Celcon but I had a plasterer lay the sand/cement on top as I thought it would be nicer to have it level!:joker:

I would not have known this was a floating floor (which I thought had something to do with loose laying those awful laminate floor planks on top of foam underlay). But you live and learn.

Thanks.

It's the foam layer that classes it as a floating floor...as the screed is really just floating on top of it,,if you see what i mean....

p.s I think the terminolgy is a warma floor.....

Oh.
Did I mention that the screed on top is 80/100mm thick?
