Depth of pipe

Bryan_16

Looking at puttting tubing in an 8" thick concrete slab. Normally I tie the tube to mesh or staple it to the foam. Reaction time will be slower if I put the tube at the bottom of the slab, but how do I get the tube to stay in the middle?

Either do ....

2 pours...4" then pex then 4" or use chairs...Chairs are wire mesh supports that raise the tubing up into the middle of the slab...kpc
