I love the look and feel of cob with the wood elements embeded. However, local code says any wood in contact with concrete has to be treated.
I know that white oak has superior durability and have used it in lieu of treated in situations such as in the pump house when I did not want treated wood chemicals around.
Is there danger of rot if the cobwood is not white oak? And is there special treatment of the wood in contact with the cob?
Thanks,
