The Growing Concern with Vapor Intrusion In extreme cases, vapors may accumulate in dwellings or occupied buildings to levels that may pose near-term safety hazards (e.g. explosion) or acute health effects. This occurs when there is a migration of chemical-containing vapor from a subsurface source into an overlying building. At [...]
Not All Vapor Barriers are Created Equal Vapor barriers…are they all the same? What is the difference between a vapor barrier and a moisture barrier? Isn’t a water vapor barrier the same as soil and gas vapor barrier? Chemical vapor venting channel designed to divert dangerous vapor away from a building. [...]
CONSTRUCTING THE VAPOR BARRIER The general contractor needed to complete the concrete pour phase of the construction in a timely manner to stay on schedule. In order to meet these specific requirements, the vapor barrier construction would need to be finished in a single day and the installation needed to wait until [...]
