Vapor Intrusion: Below-Slab Protection Methodologies
AIA program #: DRAGO1
Length of program: 1 hour
Learning units: 1 LU/HSW
For brownfields and contaminated sites, the focus has historically been to protect human health by preventing exposure to direct contact of contaminated soil or drinking contaminated water. We now know that inhaling chemical vapors poses a potential risk to the health of residents, workers, and other occupants who are inside of the buildings. Vapor intrusion is an evolving science and it presents challenges to redeveloping these sites. This seminar provides an in-depth look at below-slab vapor intrusion protection and how it can be a sustainable tool to control transmission of chemicals into the built environment.
After attending the session, participants will gain a better understanding of the different means and methods available for protection of vapor intrusion below the building, including, but not limited to, the differences between a chemical vapor barrier and a water vapor barrier. Participants will learn the science behind vapor migration below and through concrete slabs. In addition, participants will learn what design, construction, and installation considerations can be employed to ensure success.
