running lines under slab

[urgti]

I am doing a 24x26 2 story new construction and I am to the point of where the slab will be poured this weekend I hope. Due to the second story I had to put in frost footings and a full foundation. I will be laying down the type 250 inside and out in preparation for the heated floor but first I want to run some things under that in the gravel if I can.

I plan on running electrical conduit and am wondering what type of air line can be buried or snaked through the conduit if needed.

if you embed the pvc lines in the concrete you dont have to worry about the air lines breaking. just hook steel to each end as the come out of the slab. you could een embed the flex line in the concrete. once its hard its solid.
