Concrete over rigid insulation
Concrete over rigid insulation
(OP)
This is for a small area inside a light well. The existing slab is to removed are replaced and the arch wants granular fill topped by 4" of rigid insulation topped by 4" of slab on grade. Will not have any access except for the occasional maintenance guy.
Should there by a layer of vapor retarder between concrete and insulation?

I am not actually sure about the location of the light (or even if there is one) but I would assume it would be several feet higher above this slab.
