How To BUILD A RAMMED EARTH WALL: Sustainable & STRONG!
Вставка
- Опубліковано 21 жов 2022
- In today's tutorial, we learned how to make a rammed earth wall! Rammed earth is composed of clay, sand, gravel, and a small portion of cement to act as a stabilizer. Ray shows us some of his completed projects in Tuscon, and then we dive into the demo!

I've lived in old pise houses (>50 years) old. There are many different ways, including the most common Australian method of stripping off the top soil and using to soil underneath. Preferred is more clay than sandy but if there's too much clay, add some straw to stop it cracking as it dries and that's it. Moisten in your pit, bucket to your formwork and ram. Fireproof and thermally stable, as long as you use common Australian method of one metre thick exterior walls and half metre interior walls. There's examples of similarly built walls in China and the middle east that are many hundreds, even thousands of years old and old pise houses in Australia from the days of early white colonisation.
Great work and thank you for this video. I have been searching for RAMMED EARTH HOUSES and BUILDERS for many years now. This is a very nicely done and well informative.
This s fantastic. I always wondered how this was done. You rock!
Wow bruh. You are pretty amazing with your knowledge and willingness to share. Big thumbs up. I will now probably do something like this in the future if I need to build a wall. Thank you.
I used to own an electric Bosch demo hammer which had a 4X4" tamper attachment. It seems like a good middle ground between the hand tamper and the pneumatic hammer. I once took the shank from a broken spade bit and welded the 8x8" head from a broken hand tamper to it and it. It doubled my efficiency. The only drawback was I couldn't store it in the same box as the rest of the bits. That's not even a real problem.
I've been thinking about how to get past the hand tamping part with less expense than the expensive pneumatic one that was mentioned. Thanks for the info :) Looks like I need a trip to one of the builder supply places. I'm hoping this thing isn't too expensive.
Would a modified jackhammer work?
@@zeron4081 I believe it was an SDS-Max model. This was around 2006.
I did a little digging online and found this model that looks exactly like the one I had. 11316EVS-46 14 Amp
Quite interesting. This method is quite similar to a traditional method 夯土 (hang1 tu3) used in Chinese farm houses. Nowadays, different soil mixtures are used for better strength and durability. Automated mechanical tools are used for faster packing of the earth. Surface treatment is also done to prevent erosion and improve waterproofing.
A sample 5 min video (in Chinese, but quite illustrative)

This is a really impressive building method. I'm beyond pleased to see that it's being done with such professional and natural and aesthetic results.
Rammed earth is a building material used by only three groups on the planet today: 1. The very poor, 2. The very rich, 3. The people who live in Arizona.
Gets a bad rap compared to our cardboard houses with 16" spacing. The pigmented concrete is clever and beautifully done. Kudos, and good luck on further perfecting your processes!
Ray! This video was recommended on myUA-cam feed! You’re absolutely killing it bro! Keep up the amazing, inspiring work! Much love from Lacy
Me too. Ray is a good dude.
Have you considered adding powdered basalt or basalt fibers? Basalt reacts with co2 and converts it into a mineral (dolomite, calcite, etc). I’m wondering if that would strengthen the wall even further, maybe we could reduce the amount of cement. Basalt is naturally occurring and absorbs co2 at a rate of 92%, so using it is carbon negative. Seawater hold a lot of co2, so that could be used to mix the materials instead of regular water. Some ideas!
Hey, I like the way you think
nice
Basalt! Yes. You have awesome ideas.
The Romans used sea water instead of normal water and the buildings are still strong today
That's the mineral that helps it heal it self right?
This is an excellent explanation for something I’ve been interested in doing on my property. Thank you sir. :)
thank you for teaching us. good job! greetings from Argentina
Seu trabalho é perfeito e fica lindo essas cores!!! Parabéns!!!
Thanks for sharing your knowledge with the whole world!!!
Cool idea, thanks for uploading.
thank you for the masterclass
i loved this video ! Thank you
Solid. Good drop test tip. I can imagine I'd never read about it in a book, so I'm glad you dropped that one. Makes sense. Thanks.
I watched it a couple of weeks ago. I told a buddy about it and we tried it at his house. Looks great when it's finished ill send pics ty bud
That’s so sick!!!! Thanks for sharing 🙏💙
This is inspiring & beautiful ❤
Beautiful. I love it!
very wonderful video that helped me understand the process. keep sharing keep pushing
✊🫶
Love it ❤thank you so much!!
Really good coverage of RE in short time!
Soil cement was a common way to build rural roads in the 1930's. They are very durable.
I built a rammed earth home in Georgia in 1990. The house was awesome. Super efficient and I’d put it up against an F1 Tornado any day. Not new construction but 2000 year old tech.
LOL…way to put it up against the weakest tornado
@@cjschmitt4882 : It probably would have done more, but where’s the proof. It never was hit by any tornado. However, would an F1 take out a standard stick house? Probably. Not only was it built tough, but I designed it using Florida Hurricane codes, with columns steel reinforced and tie beams to cap it off that had hurricane straps to tie down the trusses and used 5/8 plywood to sheet the roof, not 1/2 Osborn’s and trusses were 16’ on center not 24’. So it was a beast.
Can you share the pictures please
Thank you for sharing.
Greetings from France.
🙏🙏💙
thanks for the information, amigo
very informative video, thanks
🙏🙏💙
love it thanks man ;D
Great work and easy understand.
Thank you very much for sharing your knowledge.
🙏
Great video and big admirer of your work. I wish we could all get into this. Seems right.
Question, in this mixture, do you experience any shrinkage of your walls (those you have already made for clients or in testing) at the joints (where they connect to another wall)?
That is a beauty!! I wish I could do that
I love this so much!
Thank you mark! 🙏
Beautiful
Awesome information .. nice practical video... Love from india...
Parabéns! Muito corajoso e inteligente.
Great information
It’s very labour intensive, but beautiful and the bonus that it’s environmental friendly makes it worth. Thanks god, that there are people like you, who has the knowledge and willingness to do, also for the people who put extra money to order a job like this. I guess, it’s would be faster, cheaper with concrete/brick/ prefabricated materials, etc… but the ecological footprint of those technologies are much bigger, so I highly appreciate what you do.
That’s what it’s all about! Thank you Fából 🙏
the dirt is free no money
@@soltanakouider5922 WTF?
1. Soil not free in most countries.
2. It’s labour intensive and needs a lots of skills to make it right.
3. Conclusion: you are wrong 😑
Thank you for putting such informative videos online!
My husband and I I've started the preliminary process (testing small blocks like you advised in another video) of building a rammed-earth retaining wall on our property up here in Scottsdale.
Right now we are planning on making it 24in thick with rebar reinforcement & weep holes near the bottom. Any input or insight for us? Any & all input is appreciated!
0:37 "... ten thousand waves.... "
AMEN! that wall is BEAUTIFUL!
great, thank you very much.
Bro if you just hooked that pneumatic press up to a brick press you could 'pre-tamp' your materials for building sites, literally just laying the bricks down into the molds between layers of mortar. (The bricks could be hidden or visible). When there's enough pressure on raw sand or other materials they become -what engineers call- "stabilized Earth", so your pneumatic setup (and maybe a gearbox) could press out bricks that are stable at 0% concrete, then place those inside your walls using the 7 or 10% concrete materials sprinkled in between and around the bricks.
💙🙏
Smart man woe
There is a patent for a brick machine from 1865...calls for clay/sand mix and puts 65 tons of force on the dry mix to form vricks that can almost immediately be fired. They are not stable until fired, though...just super compressed.
Dude you're totally blowing his steeze...
Everyone's gonna know you can just go by bricks now. 😅
@@sethhofstetter8161 Interesting! When you say stable, do you mean resilient to water or that it's the only way it'll hold form?
Structural Engineering has a video where he mechanically stabilizes soil well enough to support the weight of a car so I really wanna learn more about building with stuff like that. -and the WASP construction printer.
Thank you
This is awesome. Thanks for sharing!
Very interesting and fine looking work.
I am building my own soil cement home.
Good advise.
Have you experimented with wetter mixes?
Imma try it. Thank you
🙏💙
Gracias por compartir, thanks for share.

Dreaming about building a hempcrete dome house with a steel frame. Indestructible!
great video
Great video! Thanks for the info. Curious why the pneumatic tamper is so expensive? That's pretty simple technology.
Nice!
Amazing thanks
🙏💙
This method of construction was used for the gift shop at the Sparrenburg Castle in Bielefeld, Germany- it looks dreadful, but it's fashionable I suppose!
In your context it looks interesting and beautiful.
@@Jj-gi2uv Romans? In Germany?
@@berserkasaurusrex4233 Yup. You know that famous building in Trier? The porta Nigra? That is a roman building. Everything south of the Rine so the deep south and Southwestern parts of Germany mostly.
Great video and very informative. Thank you.
02:35 generosity is a must 👌
Nice 👍
Very nice
In trying to reduce the cement percentage, have you considered flyash replacing a small percentage of the cement? Could be very economical and result in a better product.
Hi from Tucson Arizona
Great Work Bro! Many hands make light work but if you only have a few hands Daisey the Dancing Lady does the job although my tamper is about 35kg and I am swinging that thing on 4.2m walls check it out.
Cool!
In Indonesia it was named batako, use peneumatic press to form a block of brick.
We call them mud bricks in Australia, as opposed to rammed earth, or pise.
Those are CEBs, Compressed Earth Blocks, at least here in the US. They're actually better than rammed Earth, a lot easier to build with and more water-resistant with all the lime added in.
Great post and pl continue to share such wisdom. I understand that we go layer by layer i.e. fill one layer of the earth mix, tamp it down and then fill another layer tamp it down. If these layers are done one day it is ok that the bonding between layers will be good. But how about the bonding between layers made in a gap of 1-3 days? Could you please help me understand this? Thanks.
How well does rammed earth work in wetter climates?
Very cool. Thank you for sharing.
Ryan Long's alter ego?
I appreciate your videos! I started ramming to make a small bricks for testing like you showed us on other video. Now I’m making bench size rammed earth wall. Still with hand ramming. A question, many people seems to putting Plasticure for waterproofing. Do you mix anything like that into your mix? I wish I can come to your workshop however I’m in Australia!!!
That was good. How long does it take to cure?
A builder, a scientist and an artist, all in one. You are awesome.
🙏💙
Very interesting. How long do u let it stay in the frame before you remove it?
Excellent video guys!
🙏🙏💙
Do you guys have some documents where i can see how much foundation needs to be for how much thickness of rammed earth wall you guys recommend for housing. Thank you in advance.
In our region we are using a reinforced concrert suspended slab.
How far it works with load bearing ramped wall?
Could you tell me about pneumatic tamper you recommend please? Where can I purchase in Australia?
can it be used in very wet environments?
The community that Dennis Weaver helped started Earthship the house still holds up today is tourist attraction made with lots of bottles and cans in a self composting toilet
To construct homes using rammed earth technique, what should be ideal wall width?
So cool
🙏💙
I have a hydraulic tamper its powerful don't get a foot under it for sure. Its just so dang heavy, yeah its lighter while floating when on but it'll wear you out. This whole process will wear you out and I had a front bucket tractor. Hire this guy to do it if you are not ready to work your tail off.
I primarily see these being done in desert like areas. Can you do this sort of building say in a state like Missouri with the natural soil there?
Wow it's made out of dirt, pretty cool
Do I need to buy cement for mixing with sand and dirt? And is rammed earth wall strong/ solid enough??
Cool
What about the rain effects? I am looking to build a barn in my agricultural area and the constant irrigation around the three sides of the house coupled with a heavy monsoon spell every summer is making me nervous. Please shed some light in the water retention related concerns.
how long after you pack it do you need to wait until you can remove/reuse the forms? Is it like concrete where you need to wait 7 days until it reaches 75% harness before you can add another kind of form on top the wall and start packing more material on top of it?
this guy could make an incredible pastry chef
so true! :)
I’d like to see how it holds up in a rainstorm
the top was loose gravel dirt and seemed it would easily just soak into it from the top, it seemed it would need longer to cure and a sealant on the top? HEX coin $0.024 PZEN coin $0.0034
So I’m interested in knowing about your foundation, do you just start your walls on the ground just like that without foundation?
Amazing!
I understand that you have a course where you teach how to make a fire pit, can you tell me where to access it?
I don’t think the course is live any longer but you can reach out to him on instagram
What are you using for pigments?
Absolutely awesome! Cheers, from Brazil! In fact, the house at 1:26 in the brazilian city of Cunha, in the state of São Paulo! I love that house!
Is there a foundation?
When I did stone work, it was all about the foundation, to be thick enough and wide enough to hold the massive weight of the material used. Surely a house wall must weigh a substantial amount considering the height of the walls.
His mix and construction method and the engineer who signed off on the it, can’t expect it to be built on soil?
I’ve seen a lot of expensive stone columns, garden walls etc, slowly tilting over, because of cost cutting on the most important and critical part of the build..
Good point.
I don't have an air compressor and rental for the time needed is as much as buying one. (Both out of my price range.)
I'm one man building an entire house by myself, so hand tamping is out.
Can you recommend an Electric tamper?
I see "Demolition Hammers" with flat plates advertised and think that that may be the best solution but am concerned about shaft length being too short.
What's your best advice?
Update.
Bought an extreme power electric Demolition hammer from AMAZON.
It's heavy but will work well. Good length.
How long should it cure before you take the forms off?
I wonder if rammed earth gives off dust more/less than the usual ways houses are built
How would you attached a wood fence to this? Is that even possible? Can you drill into the rammed earth or will you just get cracks?
Do you need a foundation for a wall?
Always nice work and insightful tips.
Do You think you can erect a rammed wall over a mable or earth bag foundation?
With rods but well leveled and tampered.
I don't know what mable is, but an earthbag foundation depends on bags to hold together & there are no bags that can hold up to many tons of stone pressing down on them. All of the rammed earth houses I've seen have concrete stem walls. Some of the stem walls are below ground level in order to make the rammed earth look like it's coming straight out of the ground, but the concrete base is there.
Can you show how to do a wall, and what materials we will need, I would love to learn sooo bad
Be interested to know if this holds up in all climates or only in dry ones.
Randy Bachman has one in Canada
I used this on my RAM RANCH
I know this guy!
