What does specifying sealing of floor assemblies involve?

Specifying sealing of floor assemblies involves detailing the sealing requirements for those assemblies to effectively reduce or eliminate the entry of radon and other contaminants into a building. Proper sealing ensures that any cracks, gaps, or openings in the floor assembly are addressed, creating a barrier against the intrusion of radon gas. This process is crucial in radon mitigation as it not only involves identifying potential points of entry but also providing guidelines on the materials and techniques necessary for effective sealing.

Sealing is an essential component of a comprehensive mitigation strategy because unsealed floor assemblies can allow radon to seep into the living area from the soil below. By focusing on the detailed requirements for sealing, the mitigation specialist can help ensure that the building envelope is adequately protected from radon infiltration and other associated health risks.
