When contaminated soil or groundwater sits under a building, vapors can rise through the foundation into the air inside, the same way radon does.
We apply the same proven sub-slab technology used for radon to vapor intrusion projects across Middle Tennessee.
A system that intercepts vapors below the slab and vents them outside:
Near former industrial sites, dry cleaners, gas stations, or landfills, you could be dealing with more than radon:
Your building's construction determines the design:
A vapor intrusion concern flagged in a Phase I or Phase II environmental site assessment can hold up your closing until it's addressed:
Standards and proof matter for the system protecting your building's air:
See our customer reviews and the EPA-recognized standards of practice
We review your report or concern and assess the building
We design a tailored system for your specific building
We install, usually with minimal disruption
We verify proper suction across the building and coordinate follow-up indoor air sampling with your consultant
Our home base is Nashville and Middle Tennessee, and we take on commercial vapor intrusion projects in the surrounding states.
Middle Tennessee is our home base, with commercial projects in Kentucky, Alabama and Georgia.
Vapor intrusion happens when vapors from contaminated soil or groundwater migrate up through a foundation into indoor air, using the same pathway as radon.
Not exactly. Radon is a naturally occurring soil gas, while vapor intrusion usually refers to chemical vapors, such as VOCs, from nearby contamination. They enter buildings the same way, so the fix is often similar.
Most often with sub-slab depressurization or sealed vapor barriers with suction, which vent soil gas outside before it can enter. Well-designed systems can reduce indoor vapor levels by 90% or more.
Both. Homes near former industrial sites, dry cleaners, gas stations, or landfills can be affected alongside radon.
It's often first flagged in a Phase I environmental site assessment, then confirmed by testing indoor air and sub-slab soil gas, typically in a Phase II assessment.
It can, until it's addressed. We install on the deal's timeline with documentation for your lender or consultant.
Yes. We verify proper suction across the building at installation and coordinate follow-up indoor air sampling with your consultant. Active systems are built to run, and be monitored, over the long term.
