Hello all,
I am trying to get technical clarity on this subject without emotional opinions.. I have called my local building dept, the ICC and posted on another forum and can get a consensus.
I read this older post from this website
of treated for ease or ordering, availability and strength..
Anyway,, using engineered or framing lumber and adhering 6" butyl rubber would simplify things on a few levels,, Vycor says yes, has a drawing with no data, My local dept say is is OK with no data, ICC has no answer, Dupont has no advice. In the above link some contractors say they have been using Vycor/Grace for years.
Also,,,,, If greater than 8 inches above ground contact no treatment is needed??????
Thanks in advance.
Chris
