Old Dirt Basement - Need A Slab Repoured? Or Xps Directly On It?


Hi Guys.
So yesterday I looked at a basement job in an early 1900s home. The owner wanted to partially finish off their 1902 basement. It has a slab for about 30% of the space, the rest is dirt. During our talk he brought up something I would never have thought of; wondering what you guys think about it.

Can XPS be directly laid out over the dirt floor to make a new subfloor? or do the dirt areas need to be filled in with a concrete slab before putting in the xps.

I never thought of using xps directly on a dirt floor basement...the eventual plan was to lay plywood over the xps in order to install the flooring

So what do you think? Was the owner off his rocker or would it actually work?

Thanks
~K

Why don't you hire a GC to do the remodeling, instead of fishing for answers and acting like one or visit DIY forum to get answers you seek.

Not cool Greg. What they didnt teach you in grade school; if you don't have anything constructive to say then don't say anything at all...

BTW. For everyone besides greg; I've been building for over 15 years...

Normally I would have quoted a full demo & slab repour. But the idea of only xps on the dirt floor looked like a cheaper & easier option..thereby making my bid more competitive. Simply came to the forum to see if anyone ever tried it....

Deter,
Here the order

-Dirt
-XPS
-3/4" ply
-Finish flooring

Skip repouring the slab. Approx. 30% of the floor has a slab on it already.

Sorry for being straight forward with you... and please don't take this personal, but Building with Lego's for 15 years don't count... And if you didn't noticed, let me point this out to you that this cite is for professional contractors.

Yes, because after the flip the new owner will have a brother or brother in law who knows how to find the old owner.
