ᐅ Embed underfloor heating pipes in the screed layer to the required depth

Good day,

I am planning to create an opening between the kitchen and dining room.

Everything has now been calculated by the structural engineer, the wall is supported, and the wall has already been removed.

When removing the wall, I noticed that the underfloor heating pipes run into the kitchen on the far left side, where logically the door used to be.

The problem is that the underfloor heating pipes are located right at this spot.

I do not want to tear up about one square meter of flooring in front of and after that spot to move the pipes left and right, as I might even have to remove more.

Instead, I plan to use fixing tape and crowbars to press down the floor slab and secure it there. The HEA and HEB beams would initially hover about 2cm (0.8 inches) above the underfloor heating pipes using a cantilever lift, and then I would fill the area with Pagel or Eurogrout (non-shrink grout).

Now for the question: Is it acceptable for the underfloor heating pipes to be embedded in the grout together with the support foot? Because, in my opinion, the grout should not yield and is not flexible, which might damage the underfloor heating pipes?

Best regards,
Gregor
