This is after I started tearing up the floors. You can see a dark line that I circled in red. I’ve also been taking FLIR images and spray painting where it appears damp. That’s the black mark. Most of the time, the FLIR is picking up cooler areas around cracks in the slab. I’ll have to upload that later. But the FLIR cooler images are not following the straight line where the wood was rotten. They’re usually very close to it.
Also, there was an addition to the house before I bought it. That red circled area is also where they tied in the new slab

Age of house. If found a leak in the slab, they bring everything from the attic. If a vapor barrier is not used below a slab, moisture will wick up. If no leak is found, a vapor barrier will be needed between the slab and new flooring.
Where is your location?

You may not have a leak and your moisture is coming in through the cracks. Clean the floor up real good and tape some plastic sheeting over that area of the floor. Make sure you have a tight seal with the tape and floor around the perimeter of the plastic sheeting. Watch it a few days and see if you get any condensation on the plastic sheeting.
