ALS Radon & Environmental, Inc Before & After Photos

ALS Property Associates installed a radon mitigation system at a property in Hickory Corners, MI. This property had a dirt crawl space with no vapor barrier. A 20 mill vapor barrier was installed through out the entire crawl space and sealed. Drain tile was installed under the vapor barrier and used as an extraction point for the radon system. Schedule 40 piping was run from the crawl space and to the side exterior of the home. The radon fan was installed on the exterior and vented above the roof line.

See the before and after of a crawlspace our team recently encapsulated. The encapsulation was part of the radon depressurization system we installed to mitigate the radon. The CleanSpace liner is 20 MIL thick with an antimicrobial coating and really improves the air quality and overall environment of not only the crawlspace, but the home. 

Before and after of a full crawlspace encapsulation for a radon sub-membrane depressurization. What a transformation! This system lowered the radon levels significantly and greatly improved the comfortability of the home.

ALS Property Associates installed a wall vapor barrier at a residential property in Dowling, MI. This home had an interior drainage system that ran under the slab. The water would seep down the wall to the drain tile located under the slab. This system needed to be properly sealed to prevent radon gas from entering the home. A 20 mil vapor barrier was installed on the wall and sealed below the drainage matting to allow water to seep down the wall to the drain tile. This new barrier will now stop radon gas and also prevent mold spores from entering the home from the exterior wall.

This is an example of exterior portion of a standard radon mitigation system ran for a real-estate transaction. As always, we took time to professionally install the system so it looks great and will withstand the outdoor elements.
