XPS on wall, and below slab

Trucon01

Hi All,

This weekend I'll be finishing my french drain and possibly adding 2" XPS foam, depending on what you guys tell me...

From the picture, would it be OK if I concrete beside the XPS foam? I have 7'6" ceilings so a full 8ft pc of foam will not fit and instead of cutting it, could I leave the remaining beside/under the slab? I would imagine this would help push any moisture into the drain I have below?

Thanks Gary. For a second I thought you were making fun of me, until I read those pages and saw it was possible.

Thanks for all your continued help on here!
