Sub-Slab Vapor Pin

VOCs are a large group of chemicals that can easily evaporate into the air. Some VOCs are known to be harmful to human health, and exposure to high levels of VOCs can cause a variety of health problems, including respiratory problems, headaches, and dizziness. Sub-slab vapor pins are typically installed by drilling a small hole through the concrete slab of the building. The vapor pin is then inserted into the hole and sealed in place. A soil gas sample is then collected from the vapor pin using a vacuum pump. The soil gas sample is then analyzed for the presence of VOCs. Sub-slab vapor pins are a relatively quick and inexpensive way to assess the risk of vapor intrusion. They can be used to screen buildings for potential vapor intrusion problems, as well as to monitor the effectiveness of vapor intrusion mitigation systems.
