The finishers can tool in some "cuts" for crack control. If you do it later with a saw you are seriously risking a cut tube. And the cracks might have already started by that time. Trowel grooves in during finishing if you can.
You are most likely to get cracks around your posts and especially from the ones near the door. If you hammer the sharp edges off the post footings and lay a few last minute diagonal bars or ring bars around those posts it will help. Cracks radiate from inside corners in the pour.
Be prepared to bark at the concrete crew as they walk all over your carefully laid tube where it is unsupported by bar. And be sure it is under pressure during the pour!!!!!!!
You'll love the radiant! Good luck.
Yeah, that will be my job while the real finishers are doing there thing, I want to put trowel cut joints at all the door openings and one line in between where the main wall and the machine shop wall is. Most of my piers are round and only the piers supporting the trolly tower are square. At the front door I plan on cutting a joint all the way across the opening from square corner to square corner on the inside of the opening to catch any that might want to form there. The other two post in the middle of the floor I plan on troweling in a box around them and I also added extra rebar there. And yes I plan on taking an extra dose of my meds this morning before I go out to watch over my pex tube as it is being trampled.:laughing:
