Reply to comment by Reelplayer in Remodeling a kitchen. Tongue and groove OSB for sub-floor buildup? by CaseOfBeer

Yes, great question. It was originally a crawl space, but now there is a full basement underneath.

Its possible I wasn't clear enough in the OP. The question is regarding adding another layer of OSB over the existing OSB subfloor.

My mistake. No need for tongue and groove then.
