SECTION AF103
REQUIREMENTS
AF103.1 General. The following construction techniques are intended to resist radon entry
and prepare the building for post -construction radon mitigation.
AF103.2 Subfloor preparation. A layer of gas -permeable material shall be placed under all
concrete slabs and other floor systems that directly contact the ground and are within the
walls of the living spaces of the building, to facilitate future installation of a sub -slab
depressurization system, if needed. The gas -permeable layer shall consist of one of the
following:
1. A uniform layer of clean aggregate, a minimum of 4 inches (102mm) thick. The
aggregate shall consist of material that will pass through a 2 -inch (51 mm) sieve and
be retained by a 1/4 -inch (6.4 mm) sieve.
2. A uniform layer of sand (native or fill), a minimum of 4 inches (102 mm) thick,
overlain by a layer or strips of geotextile drainage matting designed to allow the
' lateral flow of soil gases. As an alternative to the geotextile material, interior
perimeter drain tile connected to the sealed sump pit may be used.
