[Cob] floors

[Damon Howell]

Everyone...
	I'm planning to do a cob floor. My building is set into the hillside  
a few inches deep in the back. Does the floor level have to be above  
the outside ground level or just above the bottom of the drainage  
ditch? Also, can the floor level be above the foundation (cob floor  
connected to cob wall) or does the rock foundation need to come above  
the floor level (cob floor connected to rock wall)? This was  
mentioned before and was determined the only reason the foundation  
would come above the floor level would be to protect the walls in  
case the floor was flooded. Then the water would soak into the floor  
instead of draining. But if it was cob floor against cob wall the  
water would be absorbed by the wall. Either is bad news. What's the  
chances of flooding in the mountains anyway?

Thanks a bunch,
