That moisture is just coming from groundwater I think, forced up through the only porous bit of the floorplan left.
I had our water feed in replaced to decommission the leaking pipe. All heating pipes come down the walls, that's the only thing I can think that's left unless our soil pipe is cracked under there.
Actually I should probably get that checked by one of those remote camera guys.
Knocking down the wall and replacing with steel & stud wall would probably be less destructive than ripping out the concrete floor.
