Central Vacuum System Component Confusion

Corbett Lunsford

Having to special order parts for construction is always a bit of a gamble- I always seem to run out of something, and have too many of something else when all is said and done. This central vacuum system from Nutone is a little tricky since the guidance on these systems is very sketchy at the advanced level (the install manual isn’t all you need for sure, and even generally helpful online resources aren’t answering all my questions), so I’m using what I know about heat flow, pressure and flow, moisture, and contaminants to customize our system with more immediately available materials!

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.
