Norm,
The tubing I used is 1/2" Kitec XPA tubing manufactured by IPEX.
Kitec is a specially designed PEX tubing were an inner and outer layer of PEX sandwiches a layer of aluminium thus making the tubing non-permeable to oxygen.
From what I know, PEX has been used in slabs for about 30 years in Europe without failures . Obviously you have to put wire-mesh in the slab to keep any cracks from making a vertical shift thus severing the tubing.
Regards,
Mike
