[Cob] foundation

[dirtcheapbuilder-Charmaine Taylor]

Ted Owens in his new DVD about his tiny SB-adobe  house showed how he 
did a trench with rubble and Urbanite ( the word you wanted) in it, the 
a small pour of cement at the top  of X inches... so it saved on 
consumption of portland cement for  a big perimeter pour.

  you could  mortar with a lime+sand traditional mix, but it sets over a 
few days, and can't be inches thick... so if you start and have time it 
could work for you in several areas.  or a combo  of lime and cement as 
needed.
