Not sure that yours has that.

What Is Basement Condensation?
The warmer air is, the more moisture it can hold. Conversely, when air cools, it often has to release moisture. The dew on your lawn in the morning is moisture that was in the air until overnight temperatures dropped to the point where the air could not hold all of that moisture.
Sources of Basement Moisture

How can I prevent mold in my basement?
Got an old, previously-finished rec room you’re refinishing? It’s virtually guaranteed that mold will be revealed when you tear into those old walls and floors. Follow these six mold-safe demolition features and you’ll stay safe and eliminate mold spores that could otherwise grow back: 1 Seal off the basement from the rest of the house before demolition begins. 2 Buy and wear a HEPA-rated respirator before you begin demolition work. You don’t know when you’ll encounter mold before you find it. 3 Remove all building material back to the foundation walls and move gutted material out from your basement to the outdoors as soon as it comes off. 4 Have a dumpster or construction site trash bag waiting. 5 Allow two weeks for the bare basement to dry out before you rebuild walls or floors. Ventilate well if outdoor temperatures are lower than basement temperature. Use a dehumidifier if it’s warmer outside than it is inside. 6 Use basement drying time to inspect for existing mold. Kill it with a registered, non-toxic fungicide. Use a fogger or spray equipment to get mold control products into all infested areas.
