  • Vapor Intrusion: A hidden danger

    As public awareness has increased, the issue of vapor intrusion in buildings has become a significant environmental concern for building occupants, regulators and industry leaders. According to the EPA, the potential health issues vary and are dependent upon the types of chemicals and concentrations of the chemicals as well as the length of the exposure and the overall health of those that are ...


  • Modulo for Vapor Intrusion

    The system creates an under slab void that works as a capillary barrier against moisture - yet uses less concrete than other standard slab equivalents but has, at the same time, a superior load bearing capacity. This is also a “green” building product that will lower future electrical costs and contribute to LEED points on sustainable building projects. Moreover, Geoplast’s ...

  • Vapor Intrusion Update

    Vapor intrusion (VI) is a process by which chemicals in soil or groundwater migrate to indoor air above a contaminated site. VI first hit the regulatory scene in 1993 when people began to first realize that this was a primary pathway to be exposed to suburface contamination. As a result, requirements were initally ...

  • CMT simplifies Vapor intrusion monitoring

    Vapor intrusion refers to the movement of volatile chemicals from the subsurface into the indoor air of overlying buildings. The most common source is groundwater or soil contaminated with volatile organic compounds (VOCs). VOCs emit vapors that migrate into pore spaces of the soil and upward into the overlying environment. Generally, vapors enter buildings through cracks and openings in the ...
