[Cob] builders lime and foundations

[howard at earthandstraw.com]

While I don't know the conditions that would have one putting the bale walls up 8" off of the floor we do put a what we call a drain bed under the walls, usually just a 2x4 or possibly 4x4 plates filled with the space between filled with gravel or vermiculite.

I can't imagine that you could not get quality lime in your region since cob cottage does.

  a few things,
  i worked on a SB house last year just outside of town and he, the
  owner, an architect from chile originally, did a concrete radiant slab
  on grade with the stemwall made of cmu block, two blocks thick and i
  believe there was a thermal break between the two rows of cmu and the
  slab, does this reduce the amount of cement, i'm not sure?

  since it appears that the closest builders lime to british columbia is
  ohio, this is not a very bioregional material, i am now faced with
  either log walls as infill, or SB with earthen clay plaster as infill,
  or rammed earth as infill, i don't believe cob to have enough
  insulative value to be practical in this bioregion, any comments would
  be appreciated....
