Sub Membrane Depressurization - Kalamazoo, MI

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.
