Basement slabs will have cutouts to provide tubs access to sewer lines.  These cutouts have exposed soil and are radon entry points into the home. We fill these areas with expanding foam to seal it off.  

This crawlspace a damaged vapor barrier that covered the dirt floor only and did not seal against foundation wall.  We installed a new vapor barrier and sealed against the foundation wall.  Note: the after photo shows the new vapor barrier installation prior to installing the radon riser and returning the insulation to foundation wall.
