Crawlspace moisture

Post by KIM MCGOWAN » Mon Sep 11, 2017 7:54 am

I am encapsulating our crawlspace due to odors coming into the house. It is an older home and does not have a capillary break between the concrete foundation and sill plate. Ii have a vapor barrier down and will now be spaying closed cell foam on the walls and sill plate area. My question is, will I have a problem with ground moisture wicking up into the sill plate that sets directly on the concrete? Will I need to worry about this causing rot? I do not want to jack the house up to put a capillary break in. Is there another solution or is this even a big concern? I live in zone 6 - and like I said I have a dry crawlspace.

While concrete does wick moisture, unless this has been an ongoing issue and you have issues with rotting plates, installing a capillary break isn't going offer any benefits.
