Insulating a Concrete Slab Incorporating PEX
I’m looking to pour a basement slab as follows:
6″ washed 3/4″ stone- compacted
Next I’d like to tie the PEX to mesh and pour. That’s the problem. Masons hate this, PEX can get cut when control joints are cut. Chairs holding up the mesh just get crushed or are a trip hazard.
If the PEX is attached to the foam, not thinking you can put the vapor barrier over the foam / PEX, plus the PEX is under 4″ of concrete, and I understand it should be within the 4″ of concrete.
Seems this very point is a sticking point in the overall theory.
Thanks for any insights.
