At our Home (2500Sq ft 2 story, we put in superior walls in Southern NJ. The walls bulge in 1.5 inches between the verticale studs below each basement window. Some other wall sections bulge in as well. I am sure a 1 1/2 inch bulge over 24 inches is bad with concrete but it doesnt leak yet. Superior walls wont come out to look at the problems. They are terrible to deal with
