Yesterday, Chris and Justin from CRS Mechanical started stapling down the 1/2″ diameter PEX tubing that is a key element of the hydronic heating system. The tubing will be embedded in 3″ of concrete, which in my case will form the finished floor. The tubing is stapled down first; then #2 rebar is laid over it; then the concrete is poured. The staple-down phase goes pretty quickly with the right tools (a spindle for uncoiling the tubing so it doesn’t twist, and a pneumatic stapler that has a special nose that centers the staple over the tube.

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.
