Thank you ! Greetings from new brunswick

Hiya there My home burnt down and I thought I'd be rebuilding with rammed earth. I'm technically ''off grid'' so... I was wondering what type of tamper/compressor/generator would be required. So far... it looks like a tamper would require 38 cfm at 90 psi, which is a 6-8k compressor, which requires a 35kw-45kw generator, which would be a good 25k. So that would be around 35-40k just to get started with the basic pneumatic tools? Any way to do it cheaper?

Great

Discussing rammed earth without mentioning its history in Africa is an oversight bordering on racism

I'd be really interested to see some science behind building techniques of exposed solid masonry walls (no insulation) and the efficiency of thermal mass, condensation control, etc... Essentially starting over and building the science upon solid masonry walls (historic brick) vs new modern building sciences who rely solely on insulation for efficiency.

Love this idea. But was that phenolic insulation used in the walls.. what about offgassing? You say it’s permeable. But phenolics are not moisture permeable are they? couldn’t you use straw or hemp shiv. Or perhaps chopped miscanthus and lime ? For the insulation?

So, it’s a variable situation, each house and each batch of brick might be different. Same might be said for stone homes too. Quite a minefield.

This is an amazing video that I keep coming back to. Should have a lot more views and likes!

Can we expose rammed earth compound wall to rain, pl give detail if possible

Where you teaching in Toronto, physics?

I want to build a hybrid house with multiple building technologies

You are so uncomfortable during this interview and I didn’t see the other person that was involved in this talk but I’m gonna tell Jan you’re not very good at public speaking and that makes people uncomfortable. If you can’t clearly unapologetically talk about what you’re passionate about and there’s so much hesitation in your talk so much discomfort there’s a reason for that because even though it is Randers and you’re an architect or whatever nobody including you on a very spiritual level Unbeknownst to you is comfortable with what you’re trying to charge I don’t care what knowledge you have you don’t charge per square foot for knowledge it might be better for you to do the blueprints with instructions and mixing ratio‘s tools that are needed kind of like you’re creating a recipe and just sell those. That would probably be more lucrative less intensive and then you would get a flat fee for every blueprint design you sell and you can sell them to the customer who can then choose from a list that goes by state and country of qualified experienced rammed earth builders who have forms which is another thing you can design and sell for a reasonable amount of money then you take yourself out of it that’s what you contribute and you just enjoy your home in the money that you’re raking in but $175 a square foot $200 a square foot is not worth it this is Earth in cement i’m gonna put myself out there and say that to thousand or 2500 years ago the great wall of China didn’t use insulation or sensors and that part of it is you wanting to know stuff and collecting data but that’s an additional expense that doesn’t need to be if the great wall of China can stay in 2500 years nobody really cares how it’s happening except you and you going to profit from that. Where at a time in the history of humanity where people are not able to afford housing because the cost is so excessive and people cannot afford shelter which is not why these houses were designed by the tribal communities and then of course the so-called civilized people came in and killed everyone and stole their ideas and then turned around and tried to market it to people who can’t afford it this house it should be built for people who need shelter not for people who are wealthy if they want to pay for it that’s one thing but I don’t hear people talking about what can we do to help people have shelter that is safe it is comfortable that is healthy where they can grow as an individual and they can grow their own food etc. etc. I’m never going to pay somebody $200 a square foot because I don’t even make $200 a week can you imagine what the square footage would be times where I don’t make every week why is everything been stamped with a $? I live in my car for almost 4 years my daughter has a home my son has a home my other daughter lives in a trailer and my other son lives with a friend because it is almost impossible to purchase a home now I mean I have $40 to my name and I work every single day my car is my home so I don’t want to sound ungrateful but it has an indefinite shelflife because it’s been through as much as I have. I didn’t choose this I was thrown out on the street after 22 hours of abuse at high-speed‘s coming across several state lines and then discard it at a gas station by my former who is a narcissist. My son is a narcissist I’m surrounded by them and our community has become more and more so has humanity narcissistic everything is about the bottom line and the bottom line for everyone isn’t love it’s money because to them money equates power and privilege which implies that there is a polarization and then on the flipside If you don’t fit in that category are unworthy under privileged and powerless? That’s not how I see it I see it as being completely reversed and I want to call everyone’s attention to the fact that the meek will inherit the earth. These homes are made from the earth. The soil itself has life in it and it does breathe it does absorb it does feel it is a living entity and it gives itself freely to those who respect and honor it for the purpose of sheltering and then someone comes along and says I’m gonna charge you for this dirt that I did not pay for because it came with the land. Do you see how ridiculous that sounds and that’s because it is ridiculous. Wearing a great time of change and everyone has the opportunity to get on this train and ride it while it’s growing or be left behind money is going to be as good as toilet paper in the future so skills are important very important we’re not gonna be working for the middleman we’re not going to be helping them become wealthy when we become spent and pour by the years gone by. We’re going to be bringing our own gifts to the table and each person has them no one is excluded every single species has a purpose also and they are just as important as the rest of gods children and I’m not speaking in a biblical sense because I’m not actually religious I’m spiritual. We are one and we should be acting as such. What we have in our society is now his people who are very self-absorbed self-serving selfish and always looking for the next quick Buck But in a time of crisis it doesn’t matter if you’re rich man or a poor man if you go into a supermarket you’re going to have a challenge to find toilet paper right now at least in the United States with this Karana virus crap that was created in a lab in Chapel Hill North Carolina well they chemtrail us to death poison our food and water and it’s because we made it possible. If we were all doing what we could to help ourselves and supported by her communities who would chip in and vice versa when they were in need we wouldn’t need governments we wouldn’t need people who are looking to take advantage of others so they could stuff their bank counts full of money while other people are living in less than desirable or even deplorable conditions. I’m begging for people to wake up and see the potential and the fulfillment the satisfaction and the joy that comes from helping one another and not looking for something in return because the gift is in giving and I’m not asking for anything for myself but I’m asking you to look in your own communities and see where there is a need an address it because you are someone and if you’re waiting for someone to do it it’ll never get done because you’ve chosen not to. So if you’re wondering what’s going to happen with me next well I really can’t say. I have lived in the Walmart parking lot for almost 4 years every single day I get up A great son I roll up my blanket and my makeshift pillow and I put all of my things away I go to Starbucks I get a cup of hot water and put my organic sugar in there and my organic teabags and then I spend a little time with me myself and I sipping my tea taking my tinctures before I turn on my Uber and Lyft app. The consensus is is that we make a lot of money but no one seems to be aware as a customer how much money These companies are taking in commission from the driver who is Responsible for the maintenance the parts the labor the cleaning and the fuel of this vehicle never mind the exorbitant amount of money that goes into insurance and your annual tax title tag and license. Living in today’s age is not affordable it is become outlandish and there are more and more homeless people coming to stay at Walmart parking lot. Some of these people don’t have vehicles and of course we’re not seeing them at Walmart because that would be tolerable we don’t want the public to see what’s really going on right before our eyes. But the numbers are growing and then we have people of decided to live in sprinter vans because I can’t even fathom the idea of trying to keep up with what is impossible to maintain thankfully they have enough room in their vehicle to create a place where they can make food where they can store a small amount where they can work where they can sleep and some where they can shower. The sprinter vans are $50,000 so if you sold your house you could definitely manage but even then it’s not natural like Earth homes. But it does force a person to get out of the house so to speak and explore nature knowing that we are one with it and we don’t feel balanced when we’re not in it and that’s why Earth homes are so wonderful even though I personally have not had the opportunity to explore one in person. Animals love it as they stay grounded this is your anchor is a very powerful healing tool. That’s why being surrounded by it would be ideal. And of course for the traditional person when you leave this earth or your spirit does your body needs to be laid to rest and the tradition is to lay your body in the earth and compost back into all things but the chemical processes for that days tradition are so unnatural that’s actually not healthy for the earth but she can handle it and of course for humanity who like to bulldoze over graves and build housing developments So I’ve gone off track a bit but I think everyone gets the jest I would definitely become very clear on what it is about an earth home you love and not look at the money because that’s why you had such a difficult time expressing yourself you’re not comfortable with what you propositioning people and you shouldn’t be there’s a lot of people out here that need help and you are your brothers keeper we all are even if we don’t it doesn’t mean that we weren’t intended to be

Hey! I just came across this! Sounding great, Maria!

Very very cool! Thanks

is it earthquake, typhoon, flood proof like in my country philippines?

Is it only sand and earth or do you add cement?

Ratio mixing pls....

I love the uneven/sloping layers and colored layers.

In Australia out in the desert there is a lot of dirt and it was used by the First Nation people to build their own rammed earth houses.

I'm all for sustainability but this feels like a tree-hugging hippy's illusion. Until and unless they can prove that rammed earth can be made commercially and structurally viable at scale by being cost-competitive in multi-story buildings then I won't be convinced that it is a mass solution. Right now it is what it is - a one-off solution in special cases for tree huggers

I have 2 questions and a request about rammed house building. 1) How does construction of rammed earth homes integrate electric wiring and water/sewer plumbing especially for a 2 plus more floors? 2) Since the walls are made of earth, how do the walls survive in the shower or if rained on? 3) Is it possible to make/share a video that shows how the electric wiring and water/sewer plumbing lines are constructed and integrated into the walls? Answers to the above questions will be very helpful in deciding about rammed earth homes and help shed a light on how electricity and water will be incorporated in rammed earth building. Thank you so much for the informative information.

My friend maya lives in that house.

Lol I am not surprise. You sprayed the foam on the attic floor. Everyone I know sprays the bottom side of the roof decking

실비아 쿡!! 영상 참좋아요!!

I noticed the global view of areas that use rammed earth has Florida in the USA listed... but I cannot find any examples of this. We live in FL and on a tight budget but REALLY want a basic earth friendly home. Obviously we have hurricane, rainy and humid weather. Is this really an option for us? Earthbag and hemp homes almost seem impossible due to extreme labor and/or difficult to purchase building materials. Please help.

Please do not blame an improper install on a product. This is a flawed generalization.

Is this applicable in phil. ? I mean can we construct homes in the philippines used rammed earth ? (For thesis purposes)

Great info... We love our rammed earth home.

I want to do one in Morocco

Just found this vid. I'm REALLY excited about his research because I'm insulating on the inside with a masonry perimeter wall and this has been one concern I've not been able to find much science on. My perimeter is concrete block, not brick but I'm hoping there is an analogous dynamic. I am taking steps to "skin" the outside of the block so it's never exposed to the weather. I hope this will prevent a lot of moisture from getting in to the block above grade. I'll let ya know in 20 years. :) Thanks for posting this!

HI, Russ here from central Georgia, USA. Since in the south east USA we often experience months at a time when the temperature can be extremely hot with high humidity in the day time, I think rammed earth would not work because at night it may only cool off 10 degrees f. That means the walls will not get a chance to cool off, and the interior of the house would swelter day and night in the heat. Perhaps an outer layer of insulation and white reflective paint could be used so the rammed earth will not get as hot in the day, I wonder if that would work? Secondly, I find few materials here to make a keyhole garden with out spending a lot of money for construction materials , but I suspect a rammed earth version of this could work with reusable forms. A cement cap would be needed to keep the rain from washing away the dirt with the intensive rainfall we often get in the summer. The second challenge would be the plants inside the keyhole garden may erode the earthen walls, so some sort of protection would be needed to avoid that. If those problems could be solved, and reusable forms can be made, I think rammed earth keyhole gardens and retainer walls could be a good, inexpensive way to make some very attractive landscaping elements. Any comments?

I live in Richmond VA. House built 1950s. Cinder block with exterior brick. I've coated the brick with concrete sealer. The brick soaks it right up! At 50$ a gallon, it added up quickly. I've noticed an improvement especially in the winter. Before, during winter rains it seemed like the cold moisture was coming right through. Your thoughts...

Is there a way to adhere polyurethane to polyethylene?

Hi, I am the owner of an Architectural firmó in México ( Puerto Vallarta área ) I will like some technical info. as well as on site help, who do you recommend ? thank you prdconde@gmail.com thank you

There is a terrible truth to most rammed earth constructions these days that the builders try to play down. They are stabilised with CEMENT. So what does that mean ? They are NOT rammed earth , they are rammed concrete ! Once you start putting these 'stabilisers' in your aggregate and no longer use clay/lime as your binder , you have radically and irreversibly contaminated your natural earth with cement that you can never get out . The wall no longer breathes naturally . If it looks like concrete ,chances are its contaminated with concrete. YUCK !

What was the total cost of your home?

I see many rammed earth buildings that are only a single floor. If there is a second floor it appears to be wood frame construction. It appears that builders are nervous about multistory rammed earth construction. David Easton is building using rammed earth infills inside a reinforced concrete frame. Are there studies available about steel reinforced, earthquake resistant, multistory rammed earth buildings? My second question is how your wall with an insulation core compares in thermal performance to a sold rammed earth wall of the same thickness?

yes, labour intensive. cheap material, expensive labour.

Do you teach rammed earth somewhere in Ontario ???? Thanks.

Great talk. Hope to contact you soon.

All architects strive to make buildings beautiful and divide living space into the most functional plan possible, but there's no other architecture firm that we know of in Ontario that is as squarely focused on making measured energy performance their goal than Solares. Thanks Tom for sharing your thoughts!
