Radon Sump Mitigation = Very Effective.

After testing and finding out I had a radon problem, I decided to tackle the mitigation myself.

Val's website has all the info you need to complete the job and save some cash.

In my basement area (aprox 800sq ft) I had a sump pump with the old Pac-man style lid. No doubt it was a major entry source for radon.

I also had a decent sized gap all along the area where the basement slab meets the poured walls. Another source of entry.

Lastly, my huge crawl space (aprox 2500sq ft) has a vapor barrier but it is not sealed.


Using Val's site for guidance and supplies I was able to:

-design a mitigation system that would work best for my situation

-ensure all work was done within code

-seal all cracks using the radon sealant found sold on his site

-fabricate a sealed lid for my sump pump basin 

-fabricate a 4" venting system that vents directly from the sump

-install an outdoor radon fan


I'm glad to report I did not need to seal and vent the crawl space also because after completing the above work, my level fell to 1.6!

Best of all, I saved approximately $400 by doing the work myself.
