Vapor Intrusion occurs when chemical substances in soil and groundwater migrate into indoor air. This is a common problem that can have harmful effects on people and the environment. Luckily, there are ways to reduce exposure to such chemicals. Using a vapor mitigation system can help minimize the amount of vapors in your home.
how does work a Radon mitigation?
Vapor mitigation for residential homes can be done in a number of ways, depending on the type of home and the level of chemicals present. Some examples of chemicals that need mitigation include benzene, elemental mercury, and trichloroethylene. These substances can be found in soil because of spills or overuse. Even if the contamination site is long gone, vapors can penetrate the soil and make their way into a home.
Vapor mitigation involves utilizing a system to capture and vent vapors from underground. This system prevents radon from leaking into the building. The system can be installed as a sealant on the foundation or as a floor liner. The type of system to use will depend on the design of the building, the amount of chemicals it contains, and its location.
Another form of vapor mitigation is the sealing of sewers and ducts. These methods can reduce vapor concentrations by up to 90%. Another technique for reducing sewer vapor levels is depressurizing conduit, which works by altering the pressure gradient toward the sewer. The process involves installing a pump and regulator in a manhole close to a building, which draws air from the sewer through a ventilation system or carbon filter.
