Home Disasters: Earthquakes, Landslides, Sinkholes, and What To Do- Ep 306 of HOME DIAGNOSIS

Corbett Lunsford

An exploration of the natural phenomena around our homes that are unexpectedly hard or soft- hail, landslides, liquefaction of the ground during earthquakes, and the research around all of these.

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.
