Foundation Wall Airsealing, Insulation, Waterproofing

Corbett Lunsford

After 9 months of exposure, the footing of the crawlspace foundation is being buried- here are the answers to all your questions. See the finishing of the Form-a-Drain, sealing of the ForceField-concrete junction, permanent fastening of the Platon, and gluing of the 3" Rockwool ComfortBoard 80.

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.

Tuning the Enclosure of our Atlanta Home Build

Corbett Lunsford

Corbett digs into the weather barriers, structures, airsealing and insulation layers of the high performance house in Atlanta, which will be featured in season 2 of the Home Diagnosis TV series.

*CORRECTION: Pango Wrap is 15-mil thick, not 20, but is still a 0.01-perm vapor barrier.
