Hi,
I have decided to install underfloor heating in my hall and kitchen the current floor is uninsulated screed, the ceilings are a bit low so took up the 50mm screed so I can install 50mm tile backer boards something I wasn't expecting is to find a bitumen layer between the screed and slab.
Have been thinking of laying down a DPM/Radon barrier on the floor then laying the backer boards on top essentially creating a floating floor the only concern is what's the likely hood of this moving and causing the tiles to crack or damage the underfloor heating mat?
Did do some extensive research but couldn't find any answers, anyone tackled something like this before?
Thank you.
