DuWayne (Gough Concrete Specialities) poured the upper-level concrete floors last week. We specified a 3 inch slab of tinted concrete (the same 2% tint we used on the lower-level slab). A 24-inch grid of #2 re-bar is laid over the hydronic heating tubes before the floors are poured. I had them saw cut control joints in nice locations as I had on the lower level. Looks very nice, even if the floors still need some work with a Swiffer.
