What's Under All That Cement?

See our new basement floor? (No, Hoffa is not there.) It was "placed" last Thursday and then saw-cut on Friday. The saw-cuts are intended to weaken the concrete in prescribed lines so the cracks are nice and straight and not jagged random lines. Note also there are no posts. The slab was thickened under various interior walls so the walls can support the upper structure. That way we can have a rather large recreation room with no beams and posts. Actually, at the time of this post, the entire basement is framed-in and the floor trusses are being installed tomorrow.
