Radon Gas Mitigation Before & After Photos

ALS Property Associates completed a radon removal system at a residential property in Kalamazoo, MI. A sub-slab depressurization radon system was used on this property. Schedule 40 piping was run from the basement extraction point to the rear exterior. The radon fan was installed on the rear exterior and vented above the roof line.

ALS Property Associates installed a radon mitigation system at a residential property in Kalamazoo, MI. A sub-slab depressurization radon system was used and schedule 40 piping was run to the garage attic. The radon fan was installed in the attic and vented through the roof.

Here is a before/after photo of radon vent pipe located in the garage. The ALS Radon & Environmental team ran the PVC pipe from the extraction point in the basement, to the garage, and up to the radon fan located in the attic. This makes the radon reduction system not visible from the the outdoors and more aesthetically pleasing.

ALS Radon & Environmental completed a complete radon mitigation system replacement in Kalamazoo, MI. The old system was not working properly as it was installed incorrectly by another company. Thin wall pipe was hanging outside the home and the extraction point was never dug out to create an air pocket for the radon fan to remove radon gas. The old radon fan was also not rated for the basement size and soil at this property. ALS Radon & Environmental removed the entire radon system and installed a new radon system to NRPP standards. New schedule 40 piping was installed and 10 gallons of soil was removed from the extraction point. A new gx3 radon fan was properly installed with the tight soil and large basement size. 

This is an example of a dirt floor crawlspace. The before photo shows the dirt floor which is a main entry point for the radon gas. The second is the after photo after we installed drainage matting and 20 MIL Clean Space vapor barrier. This is sealed and connected to the radon system to create negative pressure under the barrier safely venting the radon gas outside of the home.
