I recently had to remove all the vinyl click floors in my basement because of water damage. The water was underneath the flooring. I've found the entry but there is no reason why it would be coming in there. I'm leaving the floors out over the winter to see if more water enters.
My question is. Should I use an insulating waterproof barrier between the concrete floor and the new floor in case the water is wicking up through the concrete or is it a waste of money. I've been told that it cause mold if the floor gets damp from condensation.
The pictures show how much water was under part of the floor. The rest was extremely damp. Approximately 1400 sq ft in 3 rooms and a hall
