How do you fix radon in a basement?
Hi - I just read, https://www.ecohome.net/guides/3218/removing-radon-gas-from-basements-and-crawlspaces/
I am looking to get down and ensure no more radon comes in, at our house is can be higher on the higher (bedroom floors) is there a solution I can implement under my floor. While my basement is finished I am not going to overlook any opportunity to make my home a safer place for my babies.
Thank you Kindly,
Hi EJ, what do you mean by under your floor? Do you mean the basement floor or are you referring to the main floor and trying to prevent radon gas in the basement air from rising to the upstairs?
Our basement is a viable living space, I want to get under the basement floor and seal out any radon. Seems there should be a system of some sort you can put over the slab... to kind of suck any permeating gases out before they enter the living space.
In that article you pasted above about how to remove radon from basements and crawl spaces it discusses radon mitigation in finished basements towards the bottom of the page, and I think your best bet may be sub-slab depressurization. That is the least intrusive way to prevent radon from entering homes if your basement is already finished.
There is one product that does what I believe you are asking, the Radon Block membrane prevents radon from passing through it but that is intended to be installed under the basement slab. You could have success with it by laying it on a bare concrete floor, then sealing all sides and lay flooring on top, but that will be a lot more work and disruption than sub-slab depressurization and likely less effective.
