July 1986 and it is still just as bone dry and solid as 20 years ago.
They like to refer to it as All Weather Wood Foundation. Thats 20
years below grade. I left one panel (under the stairs) un-insulated
and un-sheet rocked so I could keep an eve on it. From the inside it
looks like brand new. I've kept and eve on a few spots on the outside
and it's fine. There are at least 2 grades of green wood, if you use
the .60 CCA (as memory recalls), it's guaranteed for 40 yrs.
Upstate NY is known for wet rainy, snowy, so this ain't no arid
Use the pressure treated.
