Vapor Intrusion Mitigation

Sometimes, the threat of vapor intrusion is associated with naturally occurring compounds, such as methane. Dangers associated with methane include explosive environments and asphyxiation at higher concentrations. In areas where methane is known to exist in the subsurface, engineered barriers are part of the building design requirements.

The Reynolds Group’s client, a major shopping center developer, built a large retail center and needed to mitigate the possibility of methane intruding into the buildings of the center. A passive sub-slab venting system was designed and installed during the construction of the shopping center. The vapor intrusion mitigation program requires periodic monitoring of methane concentrations. TRG regularly performs these site visits at minimal cost to the management of the property.
