Hello everyone,
Certain spots on the exterior masonry of our house are consistently damp. Recently, these wet areas have also become visible on the inside walls. They do dry out during extended dry periods but always reappear when it is humid or rainy. The flat roof is already insulated and fully covered, with only the parapet still missing. I’m not sure whether the issue is related to the roof or the masonry. Do you have any advice on what might be causing this?
We plan to start with the exterior rendering soon, but I believe action is needed before that.
I appreciate any feedback or tips.
Best regards,
Michael

Filled stones should not get wet, especially not be completely saturated!
