- Dome Gaia workshop held on Kauai fall 2017 for teaching the building of inexpensive, durable, quick-built structures suitable for agriculture structures or living. Rob Cruz and Gabriel De La Cruz discussion. For a presentation by the designer, Hajjar Gibran: • Low Cost, Eco-Friendly...
I live on a hippy commune in Canada. I tore down the wood and styrofoam dome that was painted over here. It had fallen in and rotted a long time ago. There were many domes that were built near here in the 60's and 70's. The only one that survived was a concrete dome. No one lives in it now though.
It is tricky to fit products from a square world into a curved home. You need to make custom furniture and think differently about many things. Domes are natural. Beavers, birds, bees and surely other creatures live in dome shaped dwellings. You get the most interior space for the least exterior walls and roofs. There are no corners that make for poor air/heat/cooling flow. Domes are the strongest possible shape.
I went with a hexagon for my home. for me it was a nice in between of the dome that these cool dudes are working on and the traditional square home. I like it. It works for me. I was able to reuse other peoples old windows, doors, couches, beds, etc. I built it with 2x6's from my own woodlot...
There is no one way to go. I can't wait to see how this home turns out. Thanks for sharing!
Shad Oria wow that sounds awesome ! How did it go?
You can make fiberglass air crete mansion or yachts. They made concrete yachts then fiberglass,but there heavy.
@@davidsmith3736 you can use fiberglass mesh on the outside of the building to get the strength without as much weight
Fox News needs to hire this woman, no soft-ball questions! She kept me super interested in the process!
You could always listen to another station...

CNN is fake news
@DrgnFlys
In my comment where did I say Fox news is legit? I can tell you right now. Most recently CNN has reported a lot of fake news
@@islandfantasy5931 why would you say they bring fake news? What's the reasoning behind that statement?
Hahahahahaha!
The person doing the interview has very good questions
SJ R Thank you!
the younger generation are saving the planet. thank God for intelligence and persistence. God bless you and thank you for all you are doing.
I hate to piss in your cornflakes, but concrete is NOT environmentally friendly. I do really like the idea tho.
@@mrmike8490 i have no idea why you would say that.
Concrete is the most ubiquitous building material used ever. There are concrete structures built by the Roman's still in use today. Concrete has been used for thousands of years. It's continuing use testifies to its great usefulness.
@@wholegrain27 This is why i said that. 🙄
The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning, which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil. Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions.
Things to the eskimos for giving us the shape of these modern domes we never give credit where credit is due
Eskimos were not the first.... yet maybe the first with "air-ice" ... or snow as some might way. Air-crete appears to be the advantage with this setup.
Cool, either way!
What are you talking about... go away.
Using flexable sticks to make an arch then using others to form a hemisphere / dome and skin it with animal skins, mud or broad leaves was done by lots of 'peoples' everywhere from the Asian steps, to the jungles of the Amazon to Africa lands.
It's racist to say that only the Eskimo people built domes.
@@bobjoatmon1993 news flash Eskimo is a racist term it's Inuit people!
@@shawnwright5332 why the duck are you commenting to me when an earlier poster used the term and I just used it so there would be no confusion. Why didn't you comment to him?
Duck off, I've worked in north Alaska and THEY'VE INTRODUCED THEMSELVES TO ME AS Eskimos you PC fool.
May you get the education of a lifetime you richly deserve from Percussion University.
Great project! I been seeing a lot of Air-crete projects like patios or small retaining walls but this is the first I've seen of an actual structure. Very nice! I wish you all well.
Air-crete weaker than concrete... so recycling used tires make more sense for a sustainable retaining wall...
People , I’m a 43 year old General Superintendent for a commercial Drywall and Painting company in the upper Midwest of the US, MInnesota, Wisconsin , Iowa, Dakotas , and occasionally Chicago. I have been in this discipline (steel framing and finishes ) since I was 18. Upon reflection , I can’t ever remember any project that as laid back and transmitted so much good energy as this one does. VIA VIDEO MIGHT I ADD.
I can’t put my finger on it. But I want it. Perhaps it’s just the scale or the fact it’s a workshop and not a contacted build.
Leon Corriveau In your opinion, would you expect these would stand up to strong winds? Say, hurricane force? I am fascinated.
My biggest concern for Hurricane force winds would be about what heavy object could be thrown into it.
@@AkamaiBackyard Right,, but there again those flying objects would have a glancing off type of impact.
I Admired the two guys, specially the 21 year old, no laziness there. To doing this at that age is commendable
Great ppl and great interviewer!
I am so facinatdm with this! I have watched all the videos many times. I wishI could build one here in the Virgin Islands! This is my dream!
Go take one of there workshops Judith
Puerto Rico would be an excellent place to hold a workshop. I hope that's in the works.
@@AEON. - There's a dome company called "AI Domes" in Florida that has a dome home that has been at ground zero of all the major Florida hurricanes, and the only damage that has happened to any of them as a whole, is a single 6" crack in one when a DOUBLE WIDE HORSE TRAILER blew into it during the hurricane!
All the islands in the path of hurricanes like PR should mandate that ALL HOMES have to be DOME HOMES. They simple are near indestructible in the wind since there's nothing for the wind to grab...
Smart Floridians could also adopt them more on the coasts, and save throusands on hurricane insurance... They're also cheaper than traditional construction, and that's not even using Air Crete, but AI Domes own method of building them with panels...
@@AEON. The Earth Ship Home (which are cool for using water 3 times!) roofs are flat, since they catch rain water with no well water... (off grid). But yeah, air crete would be a competitor to adobe...
B Miller I was just asking this question. Thank you. I live near Panama City, near the eye of Hurricane Michael. Matter of fact, my parents rode it out in a rehab center that was right on the eye wall (dad had just been in a terrible car wreck). It was terrible. They were ok but my mom had to drive my dad an hour home bc the center was hit so hard All this with a broken neck to a house with no electricity for a month and no access to doctors or meds. It was awful. All that to say, I’m looking for something to offer more safety for people in general.
They built one in PR i got to visit it
I'm hoping to build one in Puerto Rico in a couple of years. Looks amazing, strong and lower cost.
Sodium laurel sulphate is a reducing agent for the soap to be a liquid, if you are using apoch fleece you should consider using drivit then cover it in a silicone roof coating, long life uv stable.
Great piece thank you Felicia! Wish I had seen this and hope they come back!
so glad these have made it to Kauai !! I've seen them last year online !!! Yemaya
This is a wonderful, concise explanation of the process, thank you.
4:02 she whispers "let's go ... something"
They're on point. Definitely a professional video
Now that there has been a year from this video, and hope the dome has been completed and functional, I was wondering if you are going or planning to make an update on how has the whole experience been and has the construction fulfilled your expectations, I was thinking in the sense that being from a warm climate myself, have also met with some other problems that regular concrete has, and "air-crete" being a concrete and water foam base aerated material, has moisture absorbing and structural weak properties.
DJFlores01 , just seeing this now. I will do a follow-up soon.
@@AkamaiBackyard any chance that followup is in the works?
@@AkamaiBackyard would love to see the update, is it online?
Great build ! Thank you for sharing this video with us!
How much it cost in pesos, I'm from the Philippines, I hope it cheaper and sustainable in bad weather.. thanks
Brilliant well done you guys love it Larry in London x
Love this Rob and Felicia. Bummed I missed the workshop. Hopefully another time here on the mainland.
Great video - very informative. I'm just curious how this technique holds up to snow and freezing temperatures. I'm sure you'd want to stucco and seal as much as possible, but would freezing temps cause the moisture in the air pockets to break apart? Also, could this be covered in earth for a "hobbit hole" design - would that help or hurt against freezing?
QUESTION~
The reinforcement fabric made by Apoc, would you put a layer on the inside of the structure as well or only the outside?
I am just the filmmaker, but I believe it was on the inside and the outside.
Great vid guys , It has given me plenty of food for thought , Cheers Brent
I love this idea! I've developed a dome brick molding system. While not as efficient as standard brick molding, the bricks are molded to the curvature of the dome. I believe this would add to the structural stability and ease of construction. I would love any interested people, to assist me in this project.
Jeff, where are you? I would be interested in your project. I have worked on many eco building projects and have developed an easy to install, cost effective and efficent sewage desposal system, which you could incorprate in your build.
I am going abroard on Sat 3rd July. If you contact me before then I may be able to help you.
@@peterhouston161 I am nowhere near completing this project.The molds would have to be 3D printed...and given their size..in pieces. Once created, however, they can be cast and easily recast in aluminum. I am in Las Vegas,
Question please!? I live in Irland, Will this material work in a region that constantly rains and is very humid, we only have sun two months a year!? Congratulations on the work!
It should
Air-crete is permeable.. Yes you seal it or it will take on water. If you live where it freezes, if any water gets into your structure, first freeze your building will crumble to dust.
Concrete is always permeable, same problems and solutions apply.
So, this material is fine for say... Hawaii ? or Mexico? or Philippines?
There are additives that make it water tight. Any cement brick wall is permeable.
Some sort of Styrofoam Exterior coating, though is would not be environmentally friendly would be a good candidate for waterproofing that structure.
you can sealed it by spraying already cured walls with "liquid glass" ( sodium silicate or potassium silicate ) that will also react with the concrete ,speed up the curing and improve the structural strein 10 times .
Very interesting, I am glad to see young people pushing the boundaries of what conventional construction is. I am curious as to how well aircrete handles water infiltration in a situation such as a berm home. That may simply be an incorrect application of the material, but I am unsure. Any thoughts?
speedbuggy Yes, any berm home will need to mitigate water infiltration. My concern might be the strength to hold the overburden. Domes are strong but dirt is heavy. ???
Concrete is never a good water retainer, if you want it to be then something else needs to go on top.
As for the strength, arches and domes only get stronger under compression.
Could these type of air-crete domes be built like half glass half air-crete? I love everything about these air-crete homes but for some reason I get claustrophobic looking at them with this little windows/light. Also, could air-crete domes be partly buried or would it develop mold or have other issues in time? And is it really breathable - hypoallergenic? I am having a really hard time finding something that is both breathable and natural and hypoalergenic and a material that can build a dome and be really strong. Also I haven't seen yet a video where they integrate water and sewage pipes and so on, stuff that a modern house would have, wouldn't that have to be planned and done before/during the ocnstruction?
Awesome building, great inspiration !!!
Hi! A lot of good questions and seems like interviewer just asked them impromptu, well done! I think this is the best building material of all! I hope maybe some day to make a very simple dome and be off the power grid. Be careful about breathing concrete dust. The second guy in the interview coughed, only once, but I just thought about concrete dust and wanted to mention it here.
I am the filmmaker. I did just stop by and ask questions. It was not a planned event. The video was made to support testimony on what is possible for affordable housing. It is amazing that the world has watched it, when it was simply made for a public hearing.
@@AkamaiBackyard Hi Felicia! You have a gift and do not realize it! Thanks for creating this! A great cause for a greener world!!
I can tell you that that the fiber coating on the outside is going to be VERY strong. I'd bet it would (easily) pass the 90 Mph 2x4 missile hazard test (like hurricane proof windows in Miami have to go through). Basically they shoot an 8 foot pine stud 2x4 at your window going 90 Mph. It can crack, but it MUST stop the 2x4 from going through it. AND, if I am wrong, you could always add an inexpensive wrap of medium gauge chicken wire below the fiber wrap coating, and that would do it for sure. NICE - Very nice design. I love it. I'd live in one of those in a heartbeat. And yes, someone mentioned Puerto Rico - they could really use this technology right about now.
Chicken wire might rust?
Is aircrete a good insulator from cold? I live in Pennsylvania, we can get temps.as low as 0* F. In a very cold winter.
Do you know the "R" value of your blocks ( this is an insulation value, the higher the number the better the insulating properites) awesome video!
if done correctly it averages about R-Value 2.2 per inch.. aidomes.com/aidomes-vs-aircrete/ ... suggest u check out hempcrete, such a justbiofiber.ca/ blocks too...
soooo coooool.... greetings from Canary Islands... wish you where here :-)
Built sectional mold and assemble on site and pour it full of air-crete and have a house in a day. Then move to the next location and pour another one. Laziness leads to efficiency.
In the age of the 3D printing it would be a great investment.
@@mrmike8490 They actually have that already. I watched a program on Terra-forming Mars. They had a large 3D printer that could build using this type of material. It was pretty cool. All automated and could be controlled my remote. They need to put that machine to work building homeless shelters.
@@hollywoodgold8076 The problem of homelessness is not lack of housing. or even lack of affordable housing. its more an issue of mental health and substance abuse that needs to be addressed first. A Sane and Sober person who hits hard times and ends up homeless rarely stays homeless more than a few months.
Apoligise for my nievety but do you use normal bricking morter betweem air-bricks?
Excellent questions!
why not build a dome structure form instead of bricks and fill it with aircrete
Looks like they can do small batches and bricks with less tools.
@Deimos Cain couldn't you just 36 inch ring sections, wait for it to cure then add more?
@@Toefoo100 You probably could, but it would somewhat difficult to craft these ring forms because they would be curved on two dimensions. Each ring would have it's own specifications which would be hard to travel with and/or craft all these different size rings
The way I've seen it done is they fill up a balloon then wire reinforce it and shotcrete it.
Building a dome form is pretty advanced construction compared to making a bunch of blocks. These are not contractors.
So you call this dome an Agricultural Building is this because they do not meet codes for Human Habitaion ?
Well you usually need an extensive process of approval for new houses, and depending on where you live that can cost a fortune, could be more then these entire houses.
Yes. This would not be permitted as a house.
I wonder how well this will hold up in Kansas to our tornadoes. Typical stick built homes and out buildings don’t fare well when hit directly by a tornado. Would really like to see a dome structure built here approximately 400 to 500 square feet.
Would love to see a monolithic dome utilizing aircrete...
I think in Hawaii I am done with wood frames or even foam bricks and prefer pvc Pumkin type frame covered with shade cloth and stuccoed with foam crete. mahalo
Hi, Ralph. I am working on such a system.
wow! that is fantastic! :)
can it be built 30ft diameter?
How much would it be in material?
Also, how much are the tools and the instruction?
How deep is the foundation?
Why not just lay this "fabric" over an air form?
If no stucco on the outer layer, would it still be water resistant?
I wonder if you can build this on a deck since it is lightweigt, not necessarily wood. In the oil industry, they often put buildings up on a steel I-beam foundation that is supported by pilings. The reason I ask is that in northern Alberta, we could easily have three feet of snow piling up around the house. Having it off the ground (with skirting all around for insulation) would be interesting.
Trevor Stolz , ask at www.domegaia.com. They teach the workshops and basically are evangelizing this technology. I am sure they would be helpful. I do not know. My guess is the snow would probably insulate the house like an igloo. ... I am just the filmmaker.😉
Hi, since this type of builiding is made with some cement, does the house "breath"?
Another question is, can it be used an ecological dish liquid for the mix?
Thanks
Does local regulations in Kauai allow these dome homes for actual legal residences?
No
I loved it! Thanks for sharing!
Can you please share your aircrete making method?
I mean the soap type, psi pressure. Etc
I love the idea. Another way of construction that is more material but very sturdy and more insulation is to lay the blocks flat instead of on and edge. Then inches across to form the dome. Then plaster or stucco outside and inside to finish. A raised wood floor to carry plumbing and electric..
So is the air crete not autoclaved AAC? Are the blocks heated? Also, would there be any way to just use a mold and pour the foam in without making blocks?
Blocks aren't heated, as for form pouring... well you have the very difficult task of making two dome shaped forms and then filling them without bubbles.
I want to know more about how you build the foundation
From the description it sounds like a conventional poured concrete footing and slab but the slab is aircrete.
How about coming to Jamaica we really need affordable housing like that,how can we make the trip happen?
I am in the Philippines now. I would really like to know where you did this. I will be waiting to hear from you .
This seems so simple, but it can be a struggle just to meet the legal code requirements. When I wanted to build a geodesic dome, the county wanted land density analysis, geothermal inspection, fees etc.. it's so much money just to develop the land it wasn't even worth it
If you dont cut the Form into bricks, how strong would the small wall be? I have yet to see anyone make a 1 form wall.
They keep calling it concrete, it's not ! Concrete is sand, cement, water and gravel, this is just cement, water and foam. Every building system has good and bad points you have to research each and choose what works for you and your project.
What the fuk... Portland cement has all that...
They are air rating the mix
Lighter weight better insulation value
Higher fire rating....
What would it cost me for him to do a workshop here in Tennessee. I am very intrested
I was wondering how it would do with rain as well. Also, why not build triangular molds and make it like a geodesic dome. You could also add the fabric to the mold to add strength. Maybe even some e glass fiberglass fabric. I do question how it would hold up to a strong hurricane. Probably should test it with a pressure washer to see how it will do for the rain and I would feel better with some steel as well.
How would this stand up in Hurricane weather? I live here in the U.S,but my family has land in Trinidad and I would love to be able to put this on a piece back there.How do I get in contact with you guys?
El domo in Italy used custom made modular bricks, you are a bro... but you are very hard worker.
What is the name of the fabric, is it roofing felt? Something else? What fabric thickness? What is the logic of the fabric coating?
Finally, other than looking cool if what advantage is the dome shape?
would it be easier to build a form and add debars and pout the aircrete?
dude's in shape!!
Was this finished? How is it holding up in the hurricane? Followup video?
How would this type of build handle freezing weather since there's a possibility of water seeping into a crack and freezing? I'm curious because I'd like to try to build something like this in a mountain region that sees snowfall.
Just like basic concrete this would need another layer to keep the water out.
I want to take this class sooooo bad👀
Do you have to make blocks or could you also do the collapsible bubble/balloon form?
I want one, On pylons, with a 360 patio.
O ya. Drool worthy
Regarding the floor, was there sand added to the mix or just aircrete. I lived on Kauai for 14 years and this brought back wonderful memories.
Master builder 👍🏼 looking to do similar projects.
How is the structure as it relates to earthquakes?
Nice new idea. When is next time you will be in the Philippines?
What is the maximum diameter and size of this house? Using blocks
Love it. This is a great design for gravitational and lateral forces but huge storms destroy structures by lift. It needs to be strapped down. Other than that, its a great introductory video.
How many bags of concrete does it take to make this dome and overhangs?
After the equator of the dome, does the angle or form of the air crete changes?
Is the "roofing fabric" actually tar paper??? does anyone know? Wondering, because that doesn't seem like it would be porous enough, and something like fibrglass, or nylon mesh would work better...
Not tar paper, it's a woven type fiberglass kind of fabric, I have used non-woven weed mat from Lowe's and redguard to waterproof a shower
I don't have knowledge about aircrete but its look like great and i think i am going to like the dome type of home. But my worry is.. what if it would be shaken by a quacke? I don't think so. I think i would fall because it has no still in it.
Is this like an arch with a keystone so the more pressure on it makes it stronger?
My head is spinning if it could be used underground they could build homes in the island's
that get hit with hurricanes !😇
of course it could be used underground. dewater and dig out the footprint, build the dome below grade, and backfill once all the exterior reinforcement is done. though im not sure i would want aircrete holding up much soil pressure, as it is a rather brittle product. perhaps with some testing beforehand to prove stability of the constructed wall unit.
How much would charge to build 5 domes in Costa Rica,
Very nice personality man
I think they can probably make few fiberglass mold with this project when its completed. A slice or two in the vertical section. This will help expedite completion in the future. Just my thought.
Any data on the compressive strength of the air-concrete?
About 1/10 of normal concrete Charles. Go thinshell as it uses less material than air-crete and is stronger.
What about earthquakes and hurricanes, Will they hold up?
Con que ustedes hacen los bloques que flotan?
YES AIR CRETE FELLOWS PLEASE DO A VIDEO WHEN YOU GO TO THE PHILIPPINES 👍👍👍👍👍👍👍🌞😁🇺🇸
Where in the Philippines did you build another dome?
What is the actual 'fabric' called that creates the 'skin'? Is this fabric also applied to the interior walls?
would love to meet Gabe in mexico, also where was the first one done in Mexico. I am very interested in learning how to do this to assist a few friends in Mx. that my wife and I know in very poor districts in Gurerro, specifically Zihuatanejo
Nice!
no steel cable reinforcements? what worries me are strong earthquakes, those could easily collapse the structure.
Deus Vult there not heavy so it shouldn't be as bad as having a building collapse made from wood steel and bricks. perhaps it could be placed on huge springs at the base to absorb shocks.
Photogenic Man Bun Convention
@mike brink Hello Mike....wow you're quite a smarty pants! I believe you....any more info on the idea?
aircrete not an ideal foundation material in most locations. It is too porous, it can pass water. Also, if in a flood, the house will float away unless expertly anchored.
Where in d Phl bro? I'm super interested. I'm in d visayas region. How much do u charge for a workshop? Let's help d millions of poor farmers here. Let me know pls.
How wind resistant are these buildings? The Arizona desert winds gust almost every day up to 60 mph.
cone shaped and circle objects would divert the wind around it.
60 mph winds almost every day? Where do you live? I live in the desert (near the Superstition Mt) in AZ and we never have much wind.
@@pablosteelio9462 Yucca and I'm surrounded by mountains. The wind comes down from the mountains and there's nothing stopping it. Only really hot days don't have winds until later in the afternoon.
Is it going to melt. Really? How is it with F 5?
can these aircrete homes be built underground?
Probably not. The insulation factor is good and the dome could be water proofed, but if the pressure finds one weak block it could push it in and cause a collapse. I would only recommend solid concrete w/ reinforcement for underground use. You could maybe trowel on a layer of air-crete over the solid for insulation then water proof that?
Need this. Home building needs to evolve
what is the name of the roofing fabric by Apec that you use?? Can you get it at a local hardware store like Ace Lowe's or Home Depot?
Apoc, polyester reinforcement fabric is what Gabriel says in the video. Check with www.domegaia.com
A non-stitched geo-textile would be better. The stitching lines are weak point chain. please see here for Hawaii www.geotechsolutions.com/
Make more how-to videos cool can you make a dome for underground house? How waterproof is the finished building?
Is anyone else thinking of destruction testing, 2x4x8' fired from an air cannon?
Super interested in this construction method.
Does anyone know if this material can be poured and released from forms like poured concrete?
And what of reinforcement?
Thanks.
When is your schedule for the Philippines? Thank you
hey Felicia im from the philippines is there a video of a dome made here? tnx
