anyone use spray urathane under slab

[Garage10]

Hi everyone
Have any of you ever used sprayed in urathane insulation under slab before installing in floor radiant heating instead of styrofoam or blanket insulation ?
How did it work out ? I am planning a 30x36 detached and am trying figure this out. Any help appreciated !
Thanks

Yes. We are in the process of building a 28x32 detached garage and had 1 1/2 inches of 2# (closed cell) insulation sprayed under our slab. Worked great. For the same price of the 2 inch rigid sheets I had a seamless insulating blanket installed in less than 2 hours. Concrete guys loved it; easy on the feet, concrete pushed/pulled easily, and they didn't have to deal with any seams coming apart.

Seems like a great idea. Are you working with a product that's been used like this before? Do they warranty the material and/or installation differently? How does the cured density compare to normal sheet goods?
