Sub-Membrane Depressurization is a technique used to treat radon in homes with a crawlspace. Homes with both both a basement and a crawlspace will likely need to employ this technique with a Sub-Slab Depressurization.
Crawlspace encapsulation on its own is a valuable home improvement for any house with a crawlspace. Proper encapsulation will keep moisture, mold and odor from entering your house!

The first step in a Sub-Membrane Depressurization system is encapsulating the crawlspace. Encapsulation is covering the crawlspace with plastic liner and sealing the plastic to the wall and piers. Next we run a length of perforated PVC pipe under the plastic liner. The PVC pipe will then be run either to the attic or outside. At this point we mount a radon fan.
The radon fan will pull the high radon air from under the liner (depressurizing). The exhaust will exit above the house where it will quickly dilute in the outside air.
