Before & After Photos

Check out this radon extraction point. It is tucked away in the corner of the home near the well out of the way of the rest of the basement.

This before and after photoshoot details a radon mitigation system's extraction point. The piping leads to an exterior fan that creates negative pressure under the slab. This creates a path of least resistance for the radon gas and is safely vented above the roof. 

ALS Property Associates installed a radon gas mitigation system on a residential property in Marshall, MI. A sub-slab depressurization system was run from the basement to the side exterior of the home. The radon fan was installed with an aesthetic cover and vented above the roof line.

ALS Property Associates installed a radon removal system at a residential property in Marshall, 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.

This is an example of a combination depressurization radon mitigation system. We encapsulated the crawlspace located off the basement and successfully created negative pressure under both the CleanSpace vapor barrier and basement slab. This before and after is documenting the vapor barrier with the extraction point extraction the radon gas from under the membrane.
