How long ago was the house poured and what time of year? Moisture meter the concrete. Heat on in the hóuse? Moisture meter the concrete. Heat on in the house?

What is your exterior finish? We did brick and floated the boxes in the brick not connecting to anything else on the outside....inside is attracted to cement though.

I reread your post. Since your in Canada, I assume you poured your walls in the late fall or early winter. Simply put your concrete is still wet. When pouring in the winter you have to adjust your mix. A 1 slump with a water reducer is necessary. You have to get the water out. This is what I do. The other thing you did that l do is as soon as possible cut the wire chases open and leave them open. Eps has a really low perm rating so getting the wall to dry takes a long time in winter. We don't use a top plate setup for our roofing system which leaves another route for drying. We also use a removable window and door buck system that we take out after the concrete has set this gives another path for drying. Cheer up it will dry. How long is an open question.
