A radon mitigation class visiting our project

historic KIMBALL home built 1852 project

I managed the radon mitigation portion of this complex project performed by Lamunyon Restoration. The complexities included three separate areas of crawl space, 2 of which were very difficult to access, as well as multiple footings due to all the additions to the home over the years. Happy to report the initial reading was 16pCi/l and we got the radon level below 2pCi/l despite the difficult nature of the project! We did this with 6 suction points; 3 sub slab and 3 sub-membrane! We were very proud to be able to host the field day for a radon mitigation class led by Bruce Snead and Chad Robinson. They like to take their classes to mitigation projects that present challenges in order to learn how to overcome them. Here are a few photos:

Challenge: Original duct returns ran in the dirt within the crawl space. This essentially creates a situation where the heating system was mining radon into the home. We were able to remedy!

Diagnostics being performed do determine if all areas of the slab are under negative air flow. This ensures radon levels are as low as possible.






Exterior aesthetic cover       or           interior aesthetic run

If you are concerned about the looks of your radon mitigation system, we’ve got you “covered!” Or, in most homes, we can find a way to run the mitigation pipe from the basement up to the attic and discharge out the roof. Generally we can run pipe from the basement up through a closet or even along a garage wall and then mount the fan in the attic and discharge through roof. In an interior set up you do not see the mitigation fan at all. However, as the photos below show, the cover is also a nice option.



mitigation in crawl spaces requires encapsulation

In order to create negative air pressure for radon mitigation in a crawl space, we must encapsulate the area. A PVC pipe attached to the main suction point pipe then runs underneath the encapsulation to pull radon and other soil gases from the space. We use a superior 12-20ml plastic mechanically fastened to the walls. This way it does not disintegrate or pull away therefore causing a lack of negative air pressure.
