Radon and drainage

The first photo shows the radon abatement system which is installed for future use if needed. As we are in the area most subject to radon, and we don't know if it will be an issue in the future, a radon "escape" pipe has been laid around the perimeter of the foundation with a gooseneck which you can barely see on the far wall. If in the future we find we have an issue with radon, we can then tap this pipe head and clear it from the building with an exit fan.

The second photo shows the perimeter drain we installed yesterday. In the event of excess groundwater, it is much easier and less expensive to already have a drain system than to install it later. We have two exits for this drain, but will likely choose only one for the gravity feed.
