Thanks for the picture Terry! This is exactly what I wanted to see. I'm gaining hope that my floor isn't post-tension as originally thought. And I just found a small hint that there might be a wood surface only 1" below the concrete, similar to what your photo showed.
I moved some of the insulation out of the way and found a wood floor underneath an incomplete concrete pour. So this might be what I was hoping for. Do you guys think that the concrete pour is above a wood subfloor with this picture?
