Radon Gas Mitigation Before & After Photos

It is important to encapsulate any dirt crawlspaces that may be present in your home. We then connect the radon system to the sealed crawl creating negative pressure under the membrane. This also is beneficial to your homes insulation rating and improved the overall indoor air quality.  

A sub-slab depressurization radon reduction system was installed in the basement of the home and vented above the roof line in the rear corner. A sump-pump cover was installed and sealed to prevent radon gas from entering the home and to seal the slab for the radon system.

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. 

Below is a standard installation with our extended warranty. 

ALS Property Associates installed a radon reduction system at a residential property in Vicksburg, MI. A sub-slab depressurization radon system was used on this home. Schedule 40 piping was run from the basement to the garage attic. The radon fan was installed in the garage attic and vented through the roof.
