Building a Straw-Clay Tiny House | Concrete Foundation | Part 1

thanks for all the detailed instructions, great teacher!

Good job on the construction. Couple quick clarifications/suggestions for anyone that uses this for inspiration: 1. Mil is not millimeters. I think it is actually micrometers, or 1/1000th of a millimeter. 6 mm is about 1/4”. 2. Good job on doing the excavation by hand. That’s tough. Getting the compactor was wise. Would have been better to run the compactor over the gravel every 4” or so. Once you get beyond that depth, there isn’t much compaction taking place at the lower levels. 3. In addition to the vapor barrier, it is a good idea to also place a layer of rigid foam as insulation. Reduces the heat loss through the floor and makes it more comfortable to walk on. 4. A way to benefit from the relatively cool (or warm depending on the season) ground is to dig some trenches and place pipes in them with risers back to the inside of the house. This is geothermal heating/cooling. Takes advantage of the 50-ish degree ground. Looking forward to your other videos. Good job.

16:50 For those new to concrete I just wanted to point out something he did correctly here but didn't actually talk about in the video. The reinforcing bars are NOT placed on the ground, resting on the plastic sheet. They're raised up off the sheet a couple of inches. "Chairs" are used for this and you can see them supporting the bars, maintaining space between the bars and the plastic.

Excellent new ancient technology but technique for me. Thanks

You are getting Buffed !! 🙂

Hahah, thanks. If you say so. I haven't been to the gym in over a year. Just been working and building.

I love your work. Inspirational!

Do you have a video with you laying the rebar?

[@sarebear5207]

Thanks heaps for the video

Hi! I've been learning so much from you, thank you for posting all of these videos. I was wondering, for the section of the foundation frame that's raised up off the ground, what happens when you pour the concrete. Does it seep out from underneath the 2x4's? How do you address that? Thank you!!!

[@HistoricHomePlans]

Yes, normally a little bit does. But usually it's not enough to be a problem. If the gap is more than about 2" you may start to have a small problem. But that shouldn't happen if you've properly leveled the area and put the gravel down level too.

[@johnlee7085]

When the gap is larger, it’s common to place some extra gravel behind the form boards, or even just some of the spoils; dirt that was excavated for the foundation.

Would the foundations be much different in a more temperate wetter (but surprisingly actually less rainfall than greeneville) climate like in Ireland where it wouldnt get much above 66 or so and below 32 while also getting basically zero snow. :D

[@HistoricHomePlans]

If it's cold enough to get what's called "frost heave" then you need to be really careful and do the slab a little differently. It's more than I can cover in a comment. But look up "frost heave and foundations" online and you'll find plenty of information.

[@johnlee7085]

Regardless of where you live, always check the frostline. Your foundation needs to be deeper. Even the northern part of the USA has a frost depth a couple feet down. In colder climates, people commonly pour a stem wall foundation, and then the floor as a separate pour. A foam insulation layer is a good detail, because the ground is only about 50 degrees which is a bit cooler than most people find ideal.

I hear no reference in your description of foundation construction to air separation barrier or insulation. You must be aware how much heat can be lost from conditioned spaces when neither the foundation/sill have air/thermal protection from ground nor outside air Winter temperatures.

[@thiscobhouse]

Where I'm at it's not a requirement to insulate slabs, but you're correct. Insulating the foundation is a good idea if you're going for the thermal envelope.
