polysteryne compressiv strength? Cast on top
polysteryne compressiv strength? Cast on top
(OP)
I would need it to build up an platform of 800mm height difference
And cast a slab on top.
And I was wondering if I can just use the normal polysteryne sheets
build it 700mm up and cast the 100mm slab on top (reinforced with mesh)
would it work? Or could it sattel or spring?

However, polystyrene foam is made for the use you describe. It is typically used for insulation around and under concrete slabs. There are several strengths of the foam available. Here is a link to one rated for 25 PSI:

Why can't you throw in some gravel, or just pour the slab deeper?
Alternately, you could look at something like geofoam, which is intended to be used as a fill material. I haven't personally used it, but it's getting more common.
