Stud walls on UFH/slab

[thias]

Our floor detail is to be 100mm reinforced concrete on top of 200mm EPS insulation, with UFH pipes ran in the concrete.

If I was using screed, I'd attached the stud wall sole plates to the concrete, before fitting the insulation, pipes and screeds, but because the concrete itself will be our finished floor, I'm not sure how best to fit them?

Do I just Stixall them?

I’d always prefer to have a mechanical fixing as well as bonded.

If there are no pipes in the vicinity, either concrete screws/rawl bolts. If you’ve got pipes, what about having a stub of threaded bar embedded in the slab (presuming you know where the wall is)

Yes.
