An Unexpected Connection

We recently completed a radon mitigation project on a backsplit home. There were effectively two basement areas that were separated by a foundation wall and approximately 3 feet of elevation. They did not share a common floor slab. Based on a visual assessment, these two areas should have each required a suction point. After completing a diagnostic test, we found that the lower basement area was in fact connected to the upper basement area. One suction point was able to effectively reduce radon levels to well below Health Canada Guidelines.


This project illustrated the importance of the diagnostic investigation and basing radon mitigation system design on data rather than assumptions.
