Vapor Intrusion

Sub-Slab & Vapor Intrusion Monitoring

Monitor gases directly under the slab of buildings to determine the potential for intrusion into the indoor environment. A vacuum tight seal is made through the building’s foundation, with a unique “triple  seal” using two O-rings and a water dam that ensures that only gases from beneath the slab will be drawn into the sample train and canister. After sampling, the slab face sealing fitting is removed allowing a  temporary plug to be installed.
