How to Hotrod a Radon Mitigation System

Corbett Lunsford

We've been looking forward to showing off this system for a long time- the pipes for it were installed during foundation work at the start of construction, and now 2 years later it's finished, with the Fantech Rn4 EC fan (infinitely variable), multiple drainage systems, and a roof cap. Get the details on all the tweaks we had to use to make sure this system runs perfectly, which it's doing right now.

Testing a Radon Mitigation System

Corbett Lunsford

Corbett teams up with Fantech's aerospace engineer and radon system expert Hamid Massali to prove the radon mitigation field works, and find out how much airflow the radon fan will need to exhaust to maintain safe air quality indoors.

Corbett and Grace are not joking around- they will diagnose the crap out of the forever home they're building. Here's another example of creative testing that can tell us secrets about predicting and preventing failures in the indoor physics, chemistry, and microbiology of homes. Check out the Cirrus smoke tool, and others demo'd here: https://www.trutechtools.com/Cirrus-CWI200-Wind-Indicator

Home Ventilation for the 21st Century

Corbett Lunsford

There's a lot of mythology and misinformation about how to ventilate homes, and here Corbett shows, with the assistance of Phil Rivas from Fantech, how a perfect ventilation system gets built with 5 classes of HVI-certified equipment.

Healthy Indoors Minute: Radon Problem Solved

Corbett Lunsford

Corbett shows the simple solution used to mitigate radon in the 1960's retrofit project. One fan, one pipe, one hour, problem solved.

Geotechnical Engineering for Foundation Footings: Dirt Performance and 4-in-1 Form-A-Drain

Corbett Lunsford

Corbett hired Geoff Hebner of Padstone Geotechnical Engineering to ensure the house being built will stand for a hundred years or more.

In part 2, Corbett shows the grading and leveling process with 6-8" lifts and 4x compaction using a remote-controlled trench roller.

In Part 3, Geoff returns to run a simple geotechnical test on the compacted dirt before pouring concrete, and Corbett finds out he's not as slick as he hopes.

FINALLY, we get to pour the concrete once the footings are finished with rebar, and well-supported per Geoff’s geotech engineering specs.

How to Test for Radon

Corbett Lunsford

Building forensics guru Corbett Lunsford demonstrates how to test for pressure imbalances that might draw radon into your home, and how to REALLY find out how much radon there is in the air you're breathing. More info on the test tools used at: http://TruTechTools.com and http://Retrotec.com
