Cob: RE: Domes ...

[Kelly, Sean]

Everything I have read on this list and in other places seems to say the
same thing.  Cob Domes are a no no.  I recall reading of someone in
California who died when his cob dome collapsed on him.  I would defer
to the higher authorities here (whoever you are these days ;-) Shannon,
John(s)?) to answer the question, but all info I have seen is that cob
is not an acceptable building material for domes.

Does anyone have information on cob dome and vault building?

I've been reading a bit on Hassar Fahey's house building for the poor in
Egypt.  Fascintating, but low on "how to" and whether such techniques
could
be translated to different climates successfully.  How do they stand up
in
torrential tropical downpours?  How are they water-proofed? If you
water-proof the dome how does that affect the "breathing" of the rest of
the
building. How high are the best domes?  How can they be safely
interrupted
for a cupola? What is "corbelling"?
