Hello,
I am new to this homeowners’ forum and facing a tricky challenge that you might be able to help me with.
In my renovation project, which has been ongoing for more than 15 years, I have mold appearing in the corners of the ground floor (see sketch) because moisture is accumulating there. The load-bearing exterior wall by the old slurry pit is dry, so I can rule out moisture rising by capillary action. For that reason, I suspect the concrete ceiling is a thermal bridge causing condensation inside.
Could someone here offer a quick, practical idea?
The following options are already being considered:
(1) Insulating the concrete ceiling up to 1 meter (3 feet) away from the exterior wall, both above and below with 8 cm (3 inches) each (but what about cold rising through the "load-bearing wall"?)
(2) Cutting through the concrete ceiling on the outside, flush with the exterior wall, applying exterior insulation, and filling in or removing the slurry pit
(3) Installing an internal wall heating system that heats depending on temperature/humidity
(4) Using an indoor dehumidifier
(5) Routing the heating return pipe through the lower part of the wall to prevent cooling of the interior base
Thank you very much and best regards,
Friedrich-Wilhelm
