Our slab form was inspected yesterday and we are ready to go on pouring concrete. If the weather cooperates, we'll get the slab poured this week. In talking with Rick yesterday, he explained to me in more detail how the slab was going to work. In what is called a "post-tension" slab, those trenches you see in the picture are going to become concrete beams. Wire is run throughout them and pressure is put on the wire to pull them as supports for the slab. It's an amazingly strong foundation, which every house should be built on.
