Should I frame out my foundation walls before or after I install the subfloor?

Home Improvement Asked on May 17, 2021

I’m about to start on finishing our basement and I’m going to put down a subfloor of DMX AG along with 5/8″ T&G OSB. Should I frame out my perimeter foundation walls before the subfloor or after? If I install them before, the 1/4″ DMX gap will allow for any potential moisture to evaporate into the room. If I install the foundation walls after (and on top of) the subfloor, any potential moisture would evaporate between the wall and the foundation. Which is better?

Our house was built in 2016 and is a walkout with no water issues in the 2 years we’ve been there so far.

With the comment on 6000 lb/ sq foot I would run the DMX under the walls, I have not used DMX in the past but don't see a problem especially since its a non load bearing wall. Always a good to check with the inspector / mfg to make sure it will do the job as intended.
