...barrier I would be doing something about that, which could also help mitigate radon gas if your concrete floor has any cracks. As for installing flooring, if you don’t have a vapour barrier your concrete would always remain wet, so you probably won't have great luck with an adhesive. Here are a few pages to check out t...

...barrier on top of the footing before the forms for the foundation walls are installed. So once the concrete walls are poured, moisture can’t pass between the two.

I have a house to sell, I already have contract. we stayed 13 years in that home with full finished basement. In Radon test result is 7.5pCi/L . What should  we do and how much it will cost? Can you please suggest us what should be done. House is in very good condition.  Radon mitigation equipment such as passive radon...

Hi, I recently purchased a newly-built ground floor condominium with an accessible crawlspace.  This is in Colorado, dry climate, cold winters.  The walls of the crawlspace are insulated and the dirt floor is sealed with a vapor barrior, but my indoor floors felt cold this last winter, making my whole living space cold...

...barrier, several coats of paint, and specifically oil paint can make a suitable vapour barrier. You can even buy vapor barrier paint / vapor retarder primer. The bigger concern would be, does your home have an air barrier? More often than not over the last many decades the 6-mil poly is meant to be the air barrier as w...

Good morning, I'm looking to install radon mitigation (sub-slab suction). I understand it's not too difficult, but there are a few details I'm not sure about. 1. How can I indentify what will be the best spot to drill/install the pipe into the basement floor? 2. Is there a way to know where the drain pipes goes under t...

And yes, putting drains through the ground could contribute to higher radon levels, here is our page about mitigating radon gas in basements, have you ever tested for radon gas and are you in a high risk area? 

...barrier, and enable you to create a crawlspace radon barrier as well.  Insulating the joists is a fine idea, but I would be super careful about keeping the moisture levels down, that’s why I’d be thinking of sealing the walls as well. I have a couple of questions for you, what climate zone do you live in by the way? Ev...
