How to Make Compressed Earth Block

In this video I talk about the process of making compressed earth block. I show you the machine that I used to build my house. I will show you the machine and how it works. The machine is shown in action. I also go over the steps and important principles to follow in making your own block. By watching the process of making block this should help in clearing up some questions on "How to make compressed earth block." There are probably lots of ways to do this, in this video I show you the process that I use to make block.

[@ludvigtande1236]

So great to see. I’m surprised more you tube preppers and homesteaders don’t use this technology. There are manually compressor machines available that will pay for themselves quickly. Loved the video.

[@SustainableLiving]

Thanks for watching!

[@odiswhite8429]

I agree especially because these houses are tornado proof when built properly and bullet proof, not counting windows and doors. Also, think about other uses such as retaining walls and for homesteaders, chicken coops, loafing sheds, hog housing, fencing for small animals, raised bed gardens, etc., etc., etc. The list of uses goes on and on. In third world countries where water wells are hand dug, these bricks could not only make housing but also line the hand dug water wells as long as they have the higher concentration of cerement. You could even make s spiral staircase coming out of the hand dug water well. I am certainly considering buying one of these machines but I wonder if there is a market for the bricks once I have built the things that I want for my property, and what the going price is per brick or per brick pound, or if I would just have to sell the machine back to the manufacture.

[@odiswhite8429]

I wanted to address your question directly. These machines sell for about $120,000 to $140,000 new and $65,000 to $75,000 for 18 year old machines that have made hundreds of thousands of blocks. That's just for the compressed block machine itself and not counting the tractor with a front end loader, rear tiller, Portland cement, purchased soil, as most soils don't fit the needed ratio of clay to sand, pallets for stacking and drying, etc., etc., etc. But yeah, they would make great prepper abodes as they are almost bullet proof bunkers that will maintain a comfortable temperature most of the time. Another difficult thing with these houses is that they must be planed better than most conventionally built homes. When dealing with earthen blocks vs. 2x4s and sheet rock (think forgiving), you must make completely detailed plans for everything electrical and plumbing as compressed earthen blocks are not so easily dealt with when not planned for in the original architectural drawings. All of that said, I want one! Just think of the other uses such as retaining walls, barns, loafing sheds, raised bed gardens, fences for a cuy farm, etc. etc.

I love it, I think this is truly fantastic. But to be honest, in my humble opinion, concrete is still the best way.

[@hamadilawson4396]

I concur but I could get a considerable cost savings if you only use concrete blocks in most important section

[@robford3211]

Concrete is horrible for the environment, has high carbon foot print, has zero insulation property is very ugly aesthetically and pretty expensive, but hey who am I to argue if people think that MacDonalds is the best burger in the planet.

[@jupitereye4322]

@@robford3211 I don't think Mcdonald's is the best burger on the planet. But being an architect I'll tell you you are wrong about concrete. It is not ideal, of course, I'd rather use stone if I could all the time, but concrete is amazing. First off, regarding the footprint, the longevity of the concrete makes it actually less of an emitter than many other alternatives. It isn't on pair with rammed earth, but as we all know rammed earth has its limitation. There is no 20 storey building made of rammed earth. As for the insulation, we all know it is not to be used alone, but in conjunction with other insulative materials. Wooden houses in my opinion are one of the least environmental materials. In Canada and USA you can imagine how many trees have been cut in order to make these limited life span housing that will need to be replaced on average after 50 years. During these 50 years, you'll need to prepare it many times, replace the flooring, roof construction, etc. You have to take into account having this shorter lifetime and many repairs you will need to spend fuel for those who will come to repair it, which is way more than for some other types of buildings with better longevity. Tools used in construction have also a lifespan, they can last for decades, but eventually, you'll need to replace them. Now think how much of those more you need to manufacture because the rate of amortization is higher. Concrete is safer if done right, for seismic reasons. If done properly it offers great stability and longevity, ease of modeling, and therefore practicality and function. Some older buildings made with prefabricated concrete are still in good condition after 70-80 years, with proper maintenance. I would, if I couldn't afford stone, use concrete.

Did you have problems with getting a consistent block size? I found that when there is less moisture the blocks come out more consistent but still having about 1/8” difference. Was this a problem for you guys?

[@SustainableLiving]

Yes our block size did vary in length what we found was depending on how fast I dropped the material into the hopper of the machine then it would bottleneck and would not let the full flow of the dirt once the slide was completely opened to load the dirt. This in turn would affect the size of the block. We were never too worried about it because we were always looking for different sized blocks 2 fill in any gaps once the course was finished. We did try to slowly load the hopper and that seemed to help us and getting a more consistent size block. And that would make sense if you had more moisture in it and it would bottleneck and bind up. Also we would try to let the dirt flow naturally into the Press if you have someone constantly pushing on the dirt or using the end of a shovel to poke the dirt down into the hopper that would always create a compaction issue so we would always tell our helpers to just let it flow naturally and not try to assist. Hope this helps good luck thanks for watching

great idea to use stabilized earth blocks but the issue most people how are wanting to do this can afford spending 50-65K for a hyd press machine and the hand machine are just set up to fail taking to long to make enough block

[@tomkelly8827]

Does this house use more or less cement than a concrete house? I know there is less portland per block but the blocks wouldn't have the same strength and so you would need wider blocks. So it would be a 10" wall vs a 6" wall. I know the old 2' wide stone walls used more cement than a modern 6" concrete wall. Concrete blocks are also hollow so they save on cement that way. So while I do like the sound of earth blocks, I am having trouble imagining a reason to use them.

[@genxtech5584]

So the advantage is CEB would basically compare to a traditional Adobe wall with a higher PSI strength. This would give you the benefits of a large thermal mass with some improvements for earthquakes, higher moisture area's, more flexible architectural options, less mortar in the joints, and overall less water used during the project. Also a faster dry/cure time. Otherwise CEB would get most of the benefits of Adobe. High thermal mass, fire resistance, insect resistant, noise dampening and depending on how bad the neighborhood is bullet resistance ;) Hope this helps.

[@SustainableLiving]

Honestly it is difficult, you are right jobs are very limited and where I live people are very tight with their money, (nothing wrong with that) so it makes it difficult to endeavor in entrepreneur adventures, which is what we do. We are blessed to be debt free, we work really hard to live within our means and we do a lot of repurposing to sustain our life style. Trust me, we have been tempted to leave this area and go somewhere where there are more job opportunities. At this time and with the current events we are happy to be where we are at and stand and lift where we are at. I tell all my friends and family to work really hard to become debt free, in todays standards that is almost impossible without changing some lifestyles. I don't subscribe to everything what Dave Ramsey says, but I have adopted and morphed his thought process when he says "live like no other, so you can live like no other." Over all, I am always trying to improve in this area. When I went to Wyoming this last summer to assist with wild land fires I made a lot of money, so I may do more of this for a few months out of the year to carry us over each year. I am continually looking to find passive incomes for me and my family so we can continue this lifestyle. Over the past few years, I have been changing the way I look at employment, I used to do the 9-5 thing for many years, now I am working on trusting in my abilities and seize opportunities when they come. Basically I am relearning to embrace life again. Sorry if this got too preachy or philosophical. Hope this helps.

For creating earth blocks, a 10% Portland cement mix would indeed not be a 10 to 1 ratio. 10% cement mix means that out of every 100 parts of the mix, 10 parts should be cement. A 10 to 1 ratio would mean 10 parts of another material to 1 part cement. This would actually be a 9.09% cement mix (because 1 part cement out of 11 total parts is 1/11, which equals approximately 9.09%). - To achieve a 10% cement mix, you would need a 9 to 1 ratio of other materials to cement (because 1 part cement out of 10 total parts is 1/10, which equals 10%). So, if you're aiming for a 10% Portland cement mix in your earth blocks, you should use a 9 to 1 ratio of dirt to cement.

[@MichaelSmith-hh6ox]

If anyone could answer this, I'd be so, so thankful. Are CEB's temperature regulating properties applicable to a 6b US climate zone? I read that two feet thick walls would give a structure enough thermal mass to essentially effectively cool or heat a place. But I also read that CEB temperature regulating properties are most useful in climates like a desert, with wide swings in day time and night time temperatures.

[@SustainableLiving]

I don't know if this helps or not, but I live in the climate zone 6, in AZ, and my blocks are 12 inches thick. We heat with a wood stove. The stove is in the central part of the house and once the house gets up to temp. it really does maintain the temp. We left a few weeks to find warmer temperatures and were gone for three days. The house did cool down and it took 24 hrs before the house was back up to normal swings. We typically will have a 5 to 6 degree swing from night to morning when it gets really cold and that is not stoking the stove throughout the night. This is lows around 9 degrees. When our lows hover around 30-40 degrees the fluctuation is much less. We did put stucco on the house this summer and this has helped stabilize the temperature more. We use a swamp cooler to cool the house and it does just fine. I find cooling the house and keeping it cool is easier than the cold. Hope this helps.
