Subject: Foundation/Sill Plate question

I’m trying to find out if it is recommended to use pressure treated sill plates (as opposed to plain wood 2x6) when using ICF basement foundation walls. Our sub-contractor claims it is not necessary, but the specs. call for it. I’d appreciate any help you could give me!

Per the 2003 International Residential Code section R319.1: an approved, pressure treated lumber must be used -#2 All wood framing members that rest on concrete or masonry exterior foundation walls and are less than 8 inches from the exposed ground.

Hi Nick,




Does this meen that on a house that has a walkout basement with 2½ sides of the house that are 2 story (ranch house + basement) block or pored basement walls, would only need treated lumber on the 1½ or 2 sides that have earth against them?

The IRC Code will need to be changed along with the Ban of CCA treated lumber.
