Vapor barrier

m_uther | Posted in General Questions on

So where do you apply the termite treatment when placing on com. site?

It only make sense to get your sub grade, apply your termite treatment, then your vapor, then your gab, then your steel/wire, then your concrete.

Anything else would put your vapor at risk of being damaged, right?

That’s with 4 inch and 4 inch concrete.

    Mike,
    I'm a little confused. I'm guessing that "com. site" refers to a commercial construction site.

    I have no idea what a "gab" is.

    I don't have any experience with termite treatment, but I advise you to contact the manufacturer of the chemical that you intend to apply to find out more about application recommendations.

    If you are worried about vapor barrier placement and the possibility of vapor barrier damage, you might want to read this article: Polyethylene Under Concrete Slabs.
