Drago^® Wrap Vapor Intrusion Barrier

Vapor-forming chemicals may include:

• Volatile organic compounds (VOCs),
  such as trichloroethylene and benzene.
• Select semivolatile organic compounds, such as naphthalene.

This exposure pathway, known as vapor intrusion, is the movement of chemical vapors from the soil and groundwater into the building envelope.

• In extreme examples, there is a risk of fire or explosion.
• Other times, at levels with a detectable odor, there may be acute short-term health issues such as nausea, headache, and respiratory irritation.
• More commonly though, long-term exposure to even low-levels of certain chemical vapors may increase the risk of chronic health effects, such as cancer.
