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!
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!
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.
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.

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.
@@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.

So it was a beast.
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.
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..
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.
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.
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.
@@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 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.

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?

My Question is where does one purchase this pneumatic Tamper? It's not something you find at Home Depot or Lowe's and can rammed earth walls and homes survive very long in Sub-Arctic regions like Fort Kent Maine where Negative Farenheit Temps are common
Probably not, as there is no reinforcement in Rammed Earth. The pressure of the surrounding soil would eventually cause it to collapse inward. Concrete or reinforced masonry would be the better option.
Hey there, thanks for such an informative video! I'm curious if you have any recommendations for sourcing pigment. I've made some test blocks using LaHabra stucco color coat. I estimated that I'd need about 1400 lb of pigment to complete the walls of my project (600 cubic feet). That would make the pigment by far the most expensive material used in the construction. I'm hoping that there's a better and more affordable solution. Any help is much appreciated!
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?
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.
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?
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.
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.

What's your best advice? Update. Bought an extreme power electric Demolition hammer from AMAZON. It's heavy but will work well. Good length.
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.
Pretty much, rain will erode ruts into Rammed Earth like this. Not as quickly as some of the other soil-based materials (especially Cob), but it will crumble away if you get frequent rain. It's also very difficult to repair, unlike Cob or CEBs. Adobe or plaster-covered CEB walls would handle rain better than RE or Cob, but personally I wouldn't build with any of these "natural" alternatives in a wet or tropical environment, they really are only suitable to semi-arid areas. Stone, concrete, metal, and wood are all used in the tropics for a reason; they're the best options you have.

Considering there is concrete mixed in it holds up like a weak concrete. It'll be there for decades but steadily break apart and flake off in wetter areas, much faster in areas that freeze though because it is more water absorbent so more water will intrude and freeze unless you put some sort of water barrier on it.... And it's far from a new technology, it's ancient.

I don't want to put cement in my rammed earth walls, does anyone have any idea if that book he mentioned promotes using cement? I think using lime is enough for resistance and I think it being biodegradable is important
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!!!
I know with cob you apply lin seed oil and that water proofs it. There's mild upkeep involved but not insane. See: 500 year old cob homes in UK for example. There's also some cob structures in British Columbia. So some of the highest consistent rainfall in the world there. Earthquakes on the other hand I'm not sure. I dare say these would not fair well unless you had a solid rock foundation.
@@jpvoxdawg They wouldn't do well with earthquakes, even concrete walls have issues with them and will crack depending on the strength so I see these doing even worse since they only use a bit of concrete as binder. As an after thought.. The thickness of the wall will affect it too. Thicker it is the more resistant it will be but it would require testing but guessing there is a point of effectiveness to how thick and tall it would be. Shorter it is the less thick it needs to be.

Can you explain why you use cement in your rammed earth walls?
Stabalizes it. Makes the walls harder
Could you tell me about pneumatic tamper you recommend please? Where can I purchase in Australia?
How do you build a form that links to an extant wall?
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
I don't want to put cement in my rammed earth walls, does anyone have any idea if that book he mentioned promotes using cement? I think using lime is enough for resistance and I think it being biodegradable is important
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!!!
Very cool. Thank you for sharing.
Ryan Long's alter ego?
Will the rain effect it looks amazing
how well does tamped earth hold up to heavy rain and earthquakes?
I know with cob you apply lin seed oil and that water proofs it. There's mild upkeep involved but not insane. See: 500 year old cob homes in UK for example. There's also some cob structures in British Columbia. So some of the highest consistent rainfall in the world there. Earthquakes on the other hand I'm not sure. I dare say these would not fair well unless you had a solid rock foundation.
@@jpvoxdawg They wouldn't do well with earthquakes, even concrete walls have issues with them and will crack depending on the strength so I see these doing even worse since they only use a bit of concrete as binder.
As an after thought.. The thickness of the wall will affect it too. Thicker it is the more resistant it will be but it would require testing but guessing there is a point of effectiveness to how thick and tall it would be. Shorter it is the less thick it needs to be.
Thank you for sharing
Looking forward to building my house in Mexico with this technique
How do this walls hold up to rain
Where is this? It looks familiar..I live on 22nd and Columbus..
What's the ratio of cement to sand
