Home > Wellness > Health Library > Radon Prevention: Sub-Slab Depressurization
Sub-slab depressurization or sub-slab suction removes air that
contains radon from beneath a home or building. The air is vented outside the
building by a fan.
A pipe is installed through the foundation and into the soil or rocks
below the foundation. The air under the building travels through the pipe and
is vented outdoors. The air containing radon never enters the home or building.
This is the most common and usually the most effective way of preventing radon
from contaminating a home or building.footnote 1
