Radon Gas Mitigation Photo Album: Radon Gas Mitigation - Clinton, ON
This home in Central Huron tested for radon levels around 1,000 Bq/m3 (becquerels per meter), which is very high. Health Canada recommends taking action if you test above 200 bq/m3, though we feel that is even too high. Other parts of the world typically recommend mitigation around 100 bq/m3.We also installed a new submersible sump pump and an airtight lid with a large, clear access port.Sump pumps must have a fully sealed lid over them. When a mitigation system draws air from the sub-slab, it will pull air through the sump pump (air from the room around the uncovered sump), thereby dramatically effecting the efficiency of the radon fan.This sounds complicated, but it is building science-101 and we're happy to explain it further if you call us!Great job here Mike and Joel!
Before
An open sump liner. We need an airtight lid on this for the radon mitigation system to work.
Before
We've planned the mitigation system to go in the back corner. Once the items are moved, we can start our work.
After
This is where the radon system enters the basement floor. The fan motor runs 24/7 and draws air up through the pipe and outside of the house.
After
This sealed sump lid also has a large window on hinges that is an access point. All pipe and wire penetrations are sealed. The green glowing plug is our Zoeller M63 pump. When illuminated, it indicates there is power to the pump.
After
This is the exit point for the radon pipe to go from inside of the basement, to the outside exhaust point.
After
This is the final exhaust point of the radon mitigation system.
