ALS Radon & Environmental, Inc Before & After Photos

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. 

Interior example of a radon mitigation system completed for a real-estate transaction. Notice how clean and inconspicuous this installation is. We always take the time and make sure we are installing our systems professionally and strategically to not only effectively lower radon levels but maintain the value of the home. 

Check out the before and after photos of a sub-membrane depressurization completed by our team. We proceeded and installed 20 mil Cleanspace Vapor Barrier throughout the crawlspace. We then completely sealed it making it airtight. Our depressurization system is connected creating negative pressure under the barrier. The radon gas follows the bath of least resistance and is safely vented up above the roof. 

This before/after shows the installation of radon reduction system (Radon Mitigation Sub-Slab Depressurization System) on the outside of the home. All schedule 40 pipe along with exterior rated fasteners and screws were all used. The system significantly lowered the radon levels in the home.
