What I just remembered: These "damp spots" in the photos in the first post don’t have to be water from outside. It could be moisture that condenses on the cold concrete inside because there is, for example, a small gap or slit in the XPS insulation on the outside, residues of formwork oils, salts or similar substances that attract moisture from the room air more strongly. Or was a "test drill" done exactly there and water came out? We also had such spots during the shell construction, but they disappeared on their own once it got a bit warmer in spring. Even 2-3 degrees Celsius were enough. After moving in, the heating is always on, and then it solves itself anyway.
