warning....pretty long post
I am so fed up with Radon right now I dont know what to do. I completely sealed every single crack with poleurothane chaulking. 6 mm plastic sheeting down , padding down , 1/2 think laminated wood flooring down... Wood trim sealed with chaulking on top and on bottom.
I've never had any problems with wetness or dampness on that level.
There is absolutely no way at all from the bottom that the radon can come through. So the only place it could be coming through is through the drywall via the extreme outer parts of the foundation area. And possibly from the buildup directly underneath the flooring where it cannot escape. So its possibly seeping through from underneath the flooring / underneath the woodtrim / towards the interior drywall. Thats my final conclusion.
I still have the same levels as I had before all this work was done. Around 5 to 8 pcI . I monitor all the time and even have an accurate electronic one that monitors it every hour. I've never seen it ever go above 9pcI here...for years now I even occasionally send charcol packets for lab analysis that confirm that my electronic gauge is very accurate. Im almost at the point where I dont care anymore and im just going to live with it. Normal levels in Canada for the longest time used to be 20 pcI or under. They recently lowered the legal level to 5 pcI. Yet the u.s. level is 4 pcI . Is this going to change all the time ? I mean its not like I have 5000 pcI like some houses out there.
I have a bi-level house. I cant have a mitigation system installed since I have no gravel underneath the foundation for the gas to breathe through. I heard this was common with bi-levels. My house was built in 1993. I also have radiant heating...another pain in the ass thing that the mitigation installers around here dont want to mess with... and plus with the wood flooring installed, the only place would be the garage to install the mitigation...and thats another problem since nobody knows if the garage is on a seperate slab of concrete then the main floor. The vaccum effect wouldnt work if its on another slab. Plus theres no gravel underneath.
So I decided to take matters into my own hands today and dug underneath my foundation -
I feel exhaused with my efforts....and exhaused from the uncertainty from the 2 different mitigation estimate people i've been dealing with. Both people just didnt have a definate answer on what would work... And I hate crap like that when their like "well....we can drill one hole here...and see if that works....if that doesnt work....wellllllllllllllll...........we can drill another hole............and welllllll...........if that doesnt work............we can try something else..................and if that doesnt work.......... , etc, etc... by that time I had a brain tumor and told them to leave. I just want it to be fixed and done with, but that is not possible with radon. especially with my situation. Very aggravating.
I've also heard that the only governmental radon / lung cancer studies that have EVER been done have been with Miners. People that work thousands of feet underground... of course their going to have problems. Theres never been any household radon / lung cancer studies done... EVER. Sometimes I think its a whole corrupt government thing. Maybe the Real studies indicated that anything under 10 pcI is completely safe. But if they officially say it has to be under 4 pcI....when then they make a whole lot more money that way. A whole lot more houses end up above the legal limits.
Sorry for all my blabber, im mostly looking into any positive insight on what I can do with that hole I dug. (I sense sarcastic remarks incoming)
Seriously, I appreciate any insight. I really dont know what to do anymore with this radon.
