[Cob] Cob structures and "basements" or sunken floors

[Cats Starfire]

My thought is that since you need -- is it shoes or boots? -- on your 
structure to keep the cob away from the ground/moisture and that the stone 
foundation needs to be of something that will not allow moisture to wick up 
into the cob, that anything below ground would have to be stone as well (or 
at least not cob), since there would be no way to keep the moisture of the 
surrounding ground from seeping into the cob. But I have not read anything 
one way or the other.
