Earthy Elegance | Building A Passive Solar Greenhouse From Rammed Earth Ep09 |

- Опубликовано: 31 окт 2023
- We are building a 1300 sq ft - Geothermal, Year-Round, Rammed Earth Greenhouse.
-Footings have been installed
-Concrete poured
-Rammed earth samples completed
-Built our first frame for the rammed earth walls
-Revealed the first wall
-Framed our corner sections
In this video we are pouring, ramming and stripping our corner wall section.
This project is going to be experimental for us with construction methods that we are unfamiliar with combined with some traditional methods of construction.
We have chosen rammed earth for its thermal mass properties, as well as its organic beauty
Thank you to our friends Paul and Kayla, as well as Braden for your help!
Follow along as we take you from start to finish on this groundbreaking project.

I'm sure it's going to be just beautiful.
Rammed Earth rules!
Thank You for sharing all this , the rammed earth walls are so beautiful, your greenhouse will be wonderful :)
Hi from Saskatchewan 👋🏼❤️
That’s a lot of work. Good on you both
You both are so adorable
Nice nice nice. Hard workers. Warm love from Suriname. ❤❤❤
Thank you!!
You have good looking workers;)
Just love jojo !
The columns look absolutely amazing, can’t wait to see the finished product!
You guys are awesome! I’m on my second time watching the series! Thank you, thank you!
My question was referring to the structural engineering, and the reinforcing steel in the walls (especially below grade). My question is basically, your structural engineer obviously did the engineering and horizontal load calculations on your wall. I wondered if you could talk about or show (you did very briefly in one of the episodes) the details for the rebar in the footing to wall connection. I’m going to be building a similar project in southern Arizona, in the mountains on the Mexican border.
❤
Thanks again for watching! We appreciate the interest and kind comments!
The steel to footing connection is doweled in 4-5” with 10m (3/8”) rebar. This could also be done by installing the rebar when the concrete for footing is poured with pre-bent rebar placed in the footings. We chose to dowel in for accuracy as well as ease of moving around and setting up different wall sections throughout construction. It’s nice to reduce obstructions and hazards with rebar protruding.
Our design also has close to equal backfill on either side of the wall which balances out lateral forces. If anything we have overbuilt this structure.
Finding an engineer licensed in your area willing to work with rammed earth might prove challenging. You should start looking for options sooner than later.
Our steel within each 7” section of rammed earth is a 24” O/C grid. Cross connected at 48” intervals vertically. If you go to a reduced spacing (more steel) you literally will not have room to move within the form system while ramming.
Your wall thickness is also an important detail to consider. We will be going to 24” wide on future projects for ease of installation and room to move within the forms.
Hope this answer helps and don’t be afraid to reach out via email (info in our bio) if you have more questions.
I 've been following and want to know how the sections get connected ?? And the video editor is doing an incredible job !!!!
Hi! The rebar is extended through the forms on stand alone sections. The “infill” sections between wall sections have additional rebar tying the sections together. Hope this makes sense. We will try to explain this in an upcoming video! Thanks for watching!
Good thing James is skinny 😅 to get into those small spaces… plus you are a great worker along side James … you two never seize to amaze me … can I ask what this is that you’re building .. another form of garden …it’s absolutely beautiful with all the colours ❤❤
Yes good thing he is!!! And he’s working so hard he’s only getting skinnier!!! Yep, another garden! In the form of a year-round greenhouse 🌱👍
Nice project! I’d like to know details of how the structural retaining walls were calculated and how you plan to protect them from hydrostatic pressure and water intrusion.
Hi! Thanks for watching. I’m not sure what you mean on how they were calculated. We made sample blocks for our mix with locally available aggregates and sand. The cement ratio is 10%.
We have applied a concrete sealer on portions of wall above grade, and below grade we will use a water base roll on product as we will be growing directly in soil within the structure. On the exterior of the walls below grade we will be applying a tar/bitumen for damp roofing directing this to weeping tile and eventually a French drain system.
Thanks for watching!
The color variations; is it just the different soil colors or color pigments was added? Thanks
Incredible nice looking walls 👍👏👏👏 bravo
Thank you! We used pigment for the colour variation. Mix ratios are noted in a couple of our other videos. Thanks for watching!
@@thetielife Awesome, thanks for taking the time out to reply, God bless your life more abundantly 👍
Massive footings to hold that weight.
Pretty big. 36”x9” spec. Engineer originally designed them at 24”. I increased size so I had a little more surface area for form work. If I had gone with original engineering it is comparable to a traditional house footing in these parts. Thanks for watching!
@@thetielife It's coming out beautiful. I bet you wish you had that JCB Teleskid or the Bobcat Versihandler so you could get that slurry mixer higher. Other Options: Mecalac or some sort of rotary telehandler. Truth be told, some sort of movable conveyor belt would probably be cheaper :)
Yes the teleskid would be a dream tool for this type of work. Mighty pricey machine though!
how do you do a rammed earth wall with 30cm earth, 30cm hempcrete, 30cm earth wall, (I would love to fell I live in a bullet proof bunker given the state of the world today) as I am told you need a insulative material, like do you make the earth and then let it set and make the hempcrete straight onto it or can you do all 3 parts in one go?
Best to make the form work for the full width of your wall. Depending on your location a thermal break may or may not be necessary.
Hello, I want to ask you something. We are using steel formwork on rammed earth walls and the weather is hot. Cracks form on the surface. Why do they occur?
Are you using cement as a stabilizer? The mix could be an issue as well as the transfer of heat from the steel. If you can tarp your formwork to create shade it would reduce heat transfer. Hope this helps and good luck with your project!
is this re-inforced with steel?
Yes. 10M rebar at 24” OC grid both sides of wall.
