Hi All,
I’m looking for some advice on the best order to lay liquid damp proof membrane, self-levelling compound, and low-profile underfloor heating on an old concrete slab floor. The slab is around 90% intact, with roughly 10% cracked. A photo is attached of the current floor (the water marks are from building works - the floor is generally dry).
The UFH system is a retrofit low-profile system using 20mm panels:

I’m thinking through one of three options:
A. Liquid DPM → SLC → UFH → finished floor (engineered wood)
B. SLC → Liquid DPM → UFH → finished floor
C. Liquid (or plastic?) DPM → UFH → SLC → finished floor
Have you got any advice on the best build-up, and which SLC and liquid DPM products would be suitable?
Thanks for your help.
