The worst part is that the moisture was not from the air but from the walls themselves this would get worse after a shower of rain as the moisture would seep out the walls. Concrete sweating is the phenomena of accumulation of water droplets on the surface of concrete due to the difference in temperature of the outer environment and concrete.

The water comes from introducing warm moist air to the earth cooled surface of the concrete. This usually happens when concrete slabs and the other materials that sweat reach dew point temperature.
