Here’s another great project. This small domicile demonstrates how scoria homes are faster and easier to build than bags filled with soil, and more insulating. This doesn’t mean standard soil-filled earthbags are obsolete. There are pros and cons to each system, however, I strongly encourage using scoria bags (or pumice or other suitable lightweight fill material) if there’s an affordable supply. Thanks to Joe for taking the time to document everything and share what you’ve learned.
“Hi Owen. Wanted to let you know I just uploaded 10 new videos on my YouTube site. One is a portable solar water pump, all others are on our earthbag building.
I’ve been keeping close track of our labor and expenses. We’ve only been able to work on the building for 5-7 days at a time, several times a year so it seems to be taking a very long time. However, I added up our hours so far and was pleasantly surprised. To get to our 8′ height, ready for the bond beam, including digging the foundation, laying bags, framing and providing lintels for several windows / door openings, putting in a main beam with floor joists for loft:
392 RUNNING TOTAL HOURS
392 hours is only 9.8 40 hour weeks. If you could extrapolate this to a crew of 4 this would be about 2 ½ weeks!!!
Thanks once again for your advice, and thanks to you and Kelly for keeping up your wonderful earthbag sites. Feel free to use this info.”
