3500 psi fiber mesh concrete. No steel required for this floor

I honestly don't know, but I've seen plenty of videos where hydronic heat went in over foam that then had a reinforced slab poured over it that was intended for hefty vehicles. The foam really doesn't "squish" or compress unless you hit it with a point source, such as your kneecap.
