Environmental soil pollution can enter buildings and homes through a process called vapour intrusion. Vapour intrusion is the migration of volatile organic compounds (VOCs) that have high vapour pressure and low water solubility. They can be present in contaminated soils or groundwater.
Volatile organic compounds are produced and used in the manufacture of fuels, paints, pharmaceuticals, and refrigerants. VOCs are also present in industrial solvents, paint thinners, tetrachorethene (TCE, which is dry cleaning fluid), fuel, oxygenates (MTBE), or chlorination in water treatment systems.
When these contaminants are present in the soil there is potential for vapour migration through the surface soils into surrounding buildings, thus potentially impacting the indoor air quality and posing a health risk to the building inhabitants. This exposure is receiving increased attention by regulators, in many states and represents a significant liability risk for building owners in an evolving regulatory climate.
Unlike radon gas, which occurs naturally, the hazardous elements mentioned above are man made. They enter the soil because of accidents or industrial activities. When buildings are constructed near or on top of contaminated soil, there's a risk of hazardous vapour intrusion.
If you're concerned about vapour intrusion, Doug Lacey's Basement Systems can help. Contact us today to learn more about how we can provide you with quality vapour intrusion testing and mitigation. We offer free estimates in Lethbridge, Calgary, Medicine Hat and nearby.
Since hazardous vapour intrusion into buildings is often associated with soil contamination, Health Canada has done considerable research in this area. They provide basic information about vapour intrusion as well as detailed guidance for vapour intrusion mitigation (also called soil vapour extraction). This vapour intrusion guidance is important for all people throughout Canada to accept and use to take action.
The most common solution is to install systems often used to reduce naturally occurring radon that seeps into homes in some geographic areas. These systems, called radon mitigation systems, remove soil vapours from below basements or foundations before they enter homes.
As your local National Radon Defense Contractor, we can provide you with several quality soil vapour extraction options, including:
We can also install vapour pins for diagnostics and annual maintenance. The vapour pin is a reusable sub-slab soil gas sampling device. The vapour pin is constructed of a single piece of metal. This single piece design along with the silicon sleeve eliminates potential leak points. It is installed to provide a sealable measurement point for annual maintenance of the system.

Doug Lacey's Basement Systems is proud to be a member of the international National Radon Defense network, which has worked with Environmental Engineering firms all over North America in installing vapour Intrusion Mitigation Systems. We understand the importance of sealing, depressurizing, and communicating all the entry points of the vapour intrusion.
For an environmental cleanup project of this nature, we understand you need a company with experience to get the job done right. We are your trusted local experts for soil vapour extraction and indoor air quality services, so call us today to get started! We offer free estimates in Airdrie, Okotoks, Cochrane, Chestermere, Brooks, High River, Strathmore and throughout Greater Calgary.
