Adding On To Radon Systems

Changing things in crawlspaces can increase radon levels. In this video, I'll show you how I extended an existing radon removal system to treat a crawlspace that was sealed and encapsulated 1 year after I installed the system initially.

Hi, I have watched several of your videos and enjoy the info. I am working to drop the Rn levels in my own house and I think I have radon coming in through my basement block walls as I have good suction under my basement slab. My question is, with the encapsulation, why did that not block the radon in that area? How does it get through the plastic encapsulation? Thanks
