Diagnostic Soil Gas Solutions
Professional Radon Mitigation Systems
Radon reduction requires advanced structural diagnostics and site-specific air pressure engineering. We design and install high-performance systems tailored to your home's unique foundation.
Science-Based Radon Reduction
Every building interacts with the ground differently based on its age, architecture, and underlying geology. Simply pulling air out of a basement or crawl space is not enough; true mitigation requires altering the pressure dynamics beneath your foundation to stop radioactive gas from entering the building envelope in the first place.
At Rn86 Solutions, our installations rely on technical diagnostic testing rather than guesswork. By adhering strictly to national compliance benchmarks, we engineer customized paths of least resistance that safely reroute soil gas away from your living space and vent it above the roofline.

Our Core Mitigation Methods
Sub-Slab Depressurization
The primary standard for basements and slab-on-grade homes. We create vacuum suction pits directly beneath the concrete slab, drawing out radon before it enters your home.
Block Wall Depressurization
Used in basement homes utilizing hollow block foundations. By drawing air directly out of the wall voids, this method can work independently or alongside sub-slab systems to provide crucial extra suction points.
Sub-Membrane Depressurization
Engineered for homes built over exposed crawl spaces. We install specialized PVC piping networks directly into the dirt, allowing an active fan to pull soil gases away safely.
Crawl Space Encasement
We lay down durable, high-mil vapor barriers over exposed dirt floors, locking seams and attaching them to the foundation walls to create an impenetrable seal against moisture and raw gas entry.
Diagnostic PFE Testing
We use Pressure Field Extension (PFE) testing to monitor sub-slab air flow before choosing system components, ensuring your fan is sized perfectly without drawing excess electricity.
System Commissioning
Every installation concludes with full verification testing, system performance mapping, and visual manometers to ensure long-term functionality and absolute peace of mind.
Mitigation Engineering FAQs
When is block wall depressurization preferred over sub-slab systems?
Sub-slab depressurization is always our first choice because it covers the largest surface area beneath the floor. However, if your basement uses concrete blocks that show significant gas pathways, block wall depressurization is added to seal off the foundation voids and ensure complete pressure control.
Does a crawl space vapor barrier replace an active radon system?
No, a passive vapor barrier alone slows down moisture and gas diffusion, but it does not remove it. True sub-membrane depressurization combines a durable encasement with an active fan loop to actively extract gases and exhaust them safely outdoors.
Are active mitigation systems noisy or distracting?
When engineered properly, radon fans operate quietly. We isolate our fan setups, secure piping arrays carefully, and run exhaust pathways outside living spaces to ensure your system works quietly in the background.
