Cob: Re: earth floors

[Frances Grill]

I think I am missing something here on the road base idea. I agree that it
can be compacted into a hard surface. But regardless of it's density, isn't
it still porous? What happens when oil, milk, gazpacho, and cat urine soak
into it? Is there some sort of finish on it? Even linseed oil isn't going to
protect it from liquids from penetrating between the base particles is it?
Sounds cool if it works.
    Incidently, having worked with native hydrated lime, I would advise
EXTREME (yes, I am shouting) caution. It is dangerous....could this be one
of the reasons we have prepared lime?  Thanks. Paz, Pedro
