My internal garage brick walls get saturated with condensation, hoping you guys can shed some light as to why and how to stop it.
The walls a double skin with cavity.
Roof is ply with felt top.
Where the roof extends out past the walls all the way around, there is an gap underneath the roof so I assume their is good airflow.
The concrete was poured about two months ago to standard regs, it sits on top of a membrane and finishes an inch above ground level.
There doesn't seem to be any weather pattern to when the condensation forms, it can be the exact same conditions, 1 day condensation, 1 day bone dry, whether its rain, cold or very damp outside.
The concrete feels dry to the touch, I left a tarp on it over night and the underside of the tarp was wet with what I assume is condensation, but the concrete was dry.
Any ideas on whats causing it?
