On August 20 we installed an exterior radon mitigation system in one side of a
two-unit residence in
Breckenridge in the center of Colorado.
The next
few photos show the system after its installation.
Corner view of exterior mitigation system. Garage and front door are on the right side for this unit :
View inside the garage shows four inch piping that ties into the subslab soil
near the inside garage wall of the finished section of the home.
This could be
done because the house had no interior footer under the interior garage wall, which
is an exception to the usual situation.
System view from side of building that is located in a beautiful mountainous area:
The concrete plug, 6 inches in diameter and 5 inches thick, was cored out of the floor slab. This plug shows a pipe belongin to the floor radiant heating very close to the bottom of the concrete slab. The complication to hit one of these is an example of the many "unexpected" problems one can run into while retrofitting a radon system in an existing home:
After the system was installed we loaded our tools and rest of the material in
our van and on our trailer and we are here ready to leave.
The exterior part
of the system can be seen above our van from this viewing angle.
A Radon test will be set up Tomorrow and will be exposed for several days to the
inside air under closed-house concitions after which it will be
sent to us by
mail to determine the Post-mitigation radon concentration:
