I'm with walt on this.  I'm not any kind of expert on this, but I'm not 
sure that even hard foam would offer the kind of support that you would 
want for a floor carrying potentially large deadweight loads like 
industrial machinery.    If the winters aren't that bad as you say, just 
lay the floor below the frost line and you should be good, though I'm 
not sure you need even to do that much.  I'd far sooner sink that $4000 
into a thicker floor.  It'll buy a fair piece of readymix.
