As SBH says. Flow is used for casting in GV or leveling before a new surface layer.
It is also very expensive if you are going to cast a 7-10cm layer compared to cement.
However, it takes 3 months for regular cement products to dry out. There are some intermediate products that go faster.
And a bit more expensive of course :/

So it is the EPS concrete that is load-bearing. In my case, it would work with 17cm of cellular plastic quality S80, then 7cm of EPS, and finally 3cm of self-leveling compound with underfloor heating loops.

EPS is not load-bearing. It is a filling material with insulating properties.

I get it, it's what is underneath that should bear the load.

Thanks for the help!

I wonder how it went for the one who was supposed to fill with levelling compound on macadam.

Clipping from their website:

EPSCement should be applied in a minimum total thickness, including leveling compound/skim coat, of 50 mm. The reasons for this are that a certain thickness is required for the lightweight concrete to be self-supporting, especially when laid in floating construction, and also to prevent the mix from drying out too quickly, which can easily occur if the mix is applied too thinly.

Would it work with foam plastic, then a 10cm layer of EPS, and finally 3cm of self-leveling compound?
The material underneath supports it...
