This is one I’ve never encountered before.
The basement floor is poured concrete and appears to be intact. Minor common cracks in some areas but nothing out of line to the norm.
If an item is left on the floor for a period of approximately 3 days a puddle of water appears under the item. Doesn’t matter what the item is(cardboard box, plastic pail, wood, etc.) moisture or a puddle will form.
Anybody have ideas as to what may cause this and a possible remedy?
