Vapor Intrusion
Vapor Intrusion Vapor intrusion occurs when harmful soil contamination changes phase from liquid to vapor underground and moves upward through geologic layers and building foundations, accumulating within indoor air.
Vapor Barrier Membrane for Soil Gas Mitigation
What is a Vapor Barrier Membrane for Soil Gas Mitigation? A vapor barrier, or a sub-slab vapor membrane, is a layer of protective material that prevents toxic vapor intrusion into buildings. An impervious vapor barrier can be a combination of plastic film, fabric, and sheets. And there are also roll-on and spray-on applications. Contractors usually install…

Vapor Intrusion & Soil Vapor Testing
Vapor Intrusion & Soil Vapor Testing A vapor intrusion investigation entails the study of toxic soil gases that migrate through the subsurface and into the living spaces of structures aboveground. Geologists perform soil vapor tests to evaluate the presence of vapor-phase contamination underground. Additionally, the chemical content of the vapor samples is examined for toxicity…
