Q. FDD installations disturb the floor
slab. What is the impact of this on radon in the home?
[CITY] A. During
installation the a section of the floor slab is removed to provide access to
the plumbing beneath the floor. The new
sump is installed in this space and completely sealed around the perimeter of
the sump with new concrete. This
prevents the movement of gasses around the sides of the sump. The sump itself, which is connected to the area
below the basement floor, by the footing drains, includes a sealed and gasketed
lid that will also prevent the movement of any gas from under the floor to the
basement. Together, these two measures
prevent gas from moving from the under floor area to the basement space.
