Cob: Good Foundations

[Chandra Shakti]

I'm not quite sure why you seem determined to include cement in your mix. Is 
that just for the underground part?   I don't think you're making a mistake, 
but definately doing it the hard way. I suspect all of us prefer to do it 
the hard way. Otherwise we'd just hire a contractor to make us a stick-built 
building.

<snip>I am thinking tires in the core and a cement infill (ala Helen and 
Scott Nearing's stone walls. The cement will make a surface that I can then 
slather with a bitumen waterproofing.<snip> Please speak up if you think I'm 
making a mistake or just plain doing this the hard way.
