I guess you'd go with the method that our fearless leader outlined the other 
day--heat it up good while the floor is still wet enough to allow some 
movement of the tubes after you "pour" (or throw or dump-and-spread or 
whatever} your first layer of earthen floor mix. And again as the second 
layer dries.  I'm not sure but what you'd have to do something to cushion 
the tubing before you started pouring.\

You may need to know if the people who poured the pad did any insulation 
under it--if not, you may need to insulate the ground on the outside of the 
building--run a search on AGS and/or look at:

(hey--if you felt you had to tear up that pad/slab, you could do a stem wall 
with that!--sounds like an awful nuisance to me)

I'm not planning a radiant floor.  I may regret it, but....

I would like to learn more about the adobe on concrete floor. I am building 
on a 17 foot octagonal pad created by the previous owners, but am not happy 
with concrete and would prefer to install adobe over radiant tubing, rather 
than more concrete. If you have the details, please let me know. If it 
helps, I plan to use an earthbag stem wall.
