Earlier this month, we completed a radon mitigation installation which dropped a previous radon test of 9.0 pCi/L to less than 1.0 pCi/L in Cuyahoga Falls. Below, you’ll see the process by which we evaluated and completed the job!
After designing the system (layout, location, electrical access etc), we bore a 5″ hole in the concrete about 12″ from the exterior wall.
Next, we used an auger to help remove about 5 gallons of fill from this access point (suction pit). By design, we drilled in a perfect location which let us use the drain tile as a pressure-field extender.
Once that pit was cleaned out, we began dry-fitting our pipe. To exit the home, another 5″ hole was cut in the siding. In this scenario, we had to route the pipe around a corner, up a diagonal soffit, and eventually above the roofline.
Inside the home, we worked to seal all cracks in the slab, including the slab-to-wall crack which was likely equivalent to an 8″ round hole in the concrete!
Once everything was lined up, we began gluing and securing our pipe permanently in place. As required by Ohio law, flexible removable Fernco fittings were used to attach the fan for ease-of-service in the future. Not pictured is the weatherproof electrical connection that was installed next to the fan (switch, box).
Once everything was in-place, we installed our manometer and marked its initial reading for the customer’s reference.
That’s about it! A 4 hour job broken down into a 5 minute explanation. If you have any questions, please call 330-267-9550.
