Great video very smart explanation. Good job.

[@AmericanRadonMitigation]

Thank you, sir.

Great videos but I can't find any videos for venting a daylight/walkout basement (here or anywhere on KZbin). Going through the attic or even into the garage and through the roof would be a real pain and not DIY friendly. any suggestions?

[@AmericanRadonMitigation]

I'm not sure what you are asking?

[@mixedbeans]

@@AmericanRadonMitigation I was wondering how to add a radon system to a walkout basement. I think I figured it out. Seems to be working.

Hey Jesse, I'm a little confused how a fan will pull air from under the slab. You core a hole and dig a small cavity, but aside from that air pocket, isn't the weight of the slab and the whole house bearing down on the earth underneath it all? I mean isn't it tightly packed? Where does the air come from to feed through the fan and blow outside?

[@AmericanRadonMitigation]

Good question. Tighter soils, like clay, are less porous than slabs that have gravel or course sand below them. In those more permeable soils, it's easier to create the suction below the slab required to stop radon entry. Tighter soils often require multiple suction points to create suction under the entire home. The larger the suction point, the more surface area you draw from.

@@AmericanRadonMitigation so if it's sand or coarse gravel beneath the concrete slab, a fan can pull air without being overworked? I'd never have guessed. Thanks for your reply!

A fan isn't working hard if it's hardly moving any air. It will also consume less energy than the same fan moving lots of air.
