I've read some about sleeving in-slab tubing where is passes by a control joint.  Seems straightforward, but any things to watch out for?  What if you slip up and don't get every crossing ?  I have a 30x40 slab in one area, so a joint every 10 ft means 2 joints in one direction and 3 in the other.  Dave

i dont recommend going through control joints. Lay out your tubing so there are minimal crossings.
If you have to, go under control joints. I use some foam insulation to extend 6" on either side to give the tube some wiggle room if you have to go through.

make sure you are talking about the same thing.

some people call control CUTs control joists: a control cut is just a 1" deep or so saw cut.

with those, you can safely ignore them, as long as the cut is shallow, tubing is not too high and securely fastened.
