The blow-up style I believe is called Monolithic, but a friend of mine who has built many domes (from the 1960s to the present) suggested a really quick way to create a dome would be to either use dirt from your land or have a few truckloads delivered and mound it into the dome (or any shape the dirt can hold) shape, add rebar, cover with mesh, spray with ferrocement, repeat rebar, mesh, ferrocement and then keep it moist and covered to cure for a few weeks. Then go in and start digging the dirt out, save dirt for landscaping or to build a garage and/or other outbuildings in the same way. When you have all the dirt out of the ferrocement dome structure, go inside and spray ferrocement on the inside to finish the basic shell. There you go!

I often wonder about the engineering design, material and equipment alterations that would be needed to one of your domes in order to make a below ground root cellar for our off grid cabin. My wife and I are very interested in attending one of your workshops soon. We are avid watchers and really enjoy all of your projects! Please keep all the great inspirational work you do!!!

[@AircreteHarry]

You would need to add more layers of mesh like Basalt Mesh, Stucco Wire Mesh or Fiber Glass Mesh. 2 to 4 inches thick with an insulation layer on top you would be good to go underground.

[@mariselap9520]

This is Patrick, hello Harry. Was just meantioning to Mari you ought to put in a "root cellar" (as Dennis meantioned), cover and partially cement over placing your center dome over the top prior to your last dome on the exterior according to your plans. Gods speed brother, great video as always!!

Thank you for being Our Loyal Viewers!! Our Best to you & your Wife!

[@darrelljacobjr2120]

Instead of spraying it thin where you want your doors and windows, why not put door and window forms on the outside of the inner shell (with the forms being only as thick as the space between the shells), then spray thick all around. Leave them in place, put on the outer airform and reinforcement, inflate, more window and door forms, spray that. Then cut through the airform and screen inside the window and door forms. You'll sacrifice both the inner and outer airforms, but oh well.

[@AircreteHarry]

Welcome to the channel Darrell 👍 There are several options to make it happen, indeed. I covered many of them during the hands-on workshops & LIVE chats. You nailed it - many ways to choose from.

[@RedandAprilOff-Grid]

That big mixer and the equipment to make the aircrete would add a lot to the cost. Can the thickening agent be used in regular concrete? We have some, but now that our plans have changed, we aren't sure what else it might be good for. We also want to do earth floors in part of our house, it might be interesting to do a test batch with the thickening agent?

[@AircreteHarry]

The big mixer not needed at all, at 5:38 you can see the double paddle mixer on the floor, that's all you would need to build this dome. The big mortar mixer just make life easier. The thickening agent can be used in your concrete 4 - 6 caps per bag of Portland. I think it will help using the thickening agent for your Earth floors as well.

[@bsrcat1]

You need to make the bottom of both the interior and exterior shells thicker and then they can get progressively thinner as you get the top. If you do the math I think you'll be surprised to learn just how heavy the pressure is per square inch on the bottom of that form. Look at how water towers are built in New York City, there's a whole lot of rings of steel at the bottom and progressively none when you get towards the top that's because of the amount of pressure now you could stage your insulation pores and limit them to one foot at a time in between lifts and you wouldn't have to do crazy reinforcement on the bottom. I would just invest in a cut off saw with a masonry/rebar blade and keep my interior and exterior shells uniform.

[@AircreteHarry]

Only the inner Dome needs to be structurally sound. The outer Dome can remain thin because its soul purpose is to hold Aircrete in and to be a Waterproof Barrier by using the Latex Cement Mix. Yes, indeed, the NYC Water Towers are build that way as you mentioned - as they hold tens of thousands of lbs of pressure in. Appreciate your comment 👍

[@teddyapproved]

I’m glad I found your video, I had a theory about a way to build a similar structure to this and now I know it will work. I’d love to chat sometime and get your thoughts. For the door it might be worth the extra work to just make the wall thicker where the door is and cut it out like you did the window. Then you could shape it exactly how you want it.

[@AircreteHarry]

Welcome again, Great - glad you were able to get confirmation. For the door, yet it is true & I've successfully done it as well. There are many options how to go by. [e-mail]

[@theozarksjourneytoself-suf5420]

is it possible to build one of these with no metal, with the same strength? I might be mistaken, but it appeared that metal was used in the base?

Welcome to the channel 👍 Correct, some metal was used in the base. Yes, you may absolutely build using basalt rebar & basalt mesh.

[@JohnboyCollins]

Awesome build. I wonder, how would you go about supporting electrical with this build system? I suppose it would be pretty easy to add steel conduit before installing the second air form.

[@AircreteHarry]

Hey John! Yes, that is correct. You have it exactly right - or you may run the conduit under the slab, bringing your outlets up to the wall - where you want them. 👍 👍

Would a hypertufa like first layer work, to give you something to adhere to the Tyvex with? Soak some thin cloths in a very wet mix and drape over the Tyvex. Then from there, spray away? Love the videos.

[@AircreteHarry]

Thank you Joshua, Appreciate you 👍 I use a Mesh layer on top of the Air-Form. For the Mesh provides great support for when spraying the mix on. It gives it a grip & you can spray much faster and more on top of the Structure. Therefore Mesh is very recommended.

Hey there. I've been looking into monolithic domes for quite sometime. Always drooling when I see one. I love the concept behind them. You should see me drool when I see tattooine in star wars with all those concrete domes..haha But, monolithic is FAAAR to expensive for me. Then I came across your videos just a couple days ago and I gotta tell ya, I'm finally feeling optimistic about being able to build a concrete dome now. It NEVER dawned on me to sow house wrap to make my own airform. Thank you so much. When the time comes, I will most certainly be taking your course. Questions: Can icynene be sprayed on or in it? How about rebar like monolithic does? Can the small domes be connected or do you suggest doing a big one? Can your domes be buried? How about wind and bullet resistance? I know. The bullet ques is an odd one. I'm thinking these could make a inexpensive bugout cabin. How about plumbing and electric? Sorry for all the questions. I figure it would be best to hit you with all of them at once rather then a couple at a time over and over again..lol.. Thanks again. I'm looking forward to this. I guess I have to start watching videos to learn how to operate a sowing machine..haha

Why not use rebar? Can rebar be used with aircrete? Genuine ask. Please reply. 🙏

[@AircreteHarry]

Good evening Jill, Happy to reply to you - the reason you don't use rebar: it can vibrate itself in aircrete. Rebar needs a strong grip not something that is easily irritated & flakes eventually if in contact with rebar as mentioned. Depending on the mix & if one prefers more insulative vs stronger mix but less insulative - aircrete is brittle. My Best, Harry

Random idea: a liquid Hemp polymer soaked into hemp hurd, then added to the outermost layers (inside and out) for a stronger and smoother layer for the shell... perhaps even mixed with the concrete itself. Not sure if hemp polymers exist in large enough quantities to build with (just did a search... yup, it actually DOES exist!), but I think that might be something you'd want to try out.

Are there any weather conditions they we should take into consideration?

[@AircreteHarry]

Thank You!! 👍 👍 You are building a concrete structure that is fireproof, hurricane proof, earthquake proof, tornado proof, termite proof, (sometimes *bullet proof), so the Insurance should be low for the Dome. As far as Mortgage, - with the stamped Engineer plans I image you should be able to get a Mortgage.

We will provide you with a Structural Engineer's contact Information as well. Yes, you may make one large Dome. In actual building practice, it is easier (& I would suggest) to make many smaller Domes connected. Do not build in 55° or colder conditions because the cement won't cure correctly.

@@notonthelam5329 You are very Welcome. In the above post you mentioned using tyvek in addition to the geodesic dome tent, so you are already ready to use the tyvek material - which is good.

It's a good idea.

[@krussellgal]

Did you add more aircrete to the upper layer of the dome?

[@AircreteHarry]

Not yet, I will after I fix the problems.

[@jafinch78]

Wondering about using the open source UHPC mix for the structural shell(s)? Also, now that I have some sewing machines rescued... other more complex form designs... plus using something like a light burlap or hemp material that is first infused maybe with like the UHPC or HPC powder before inflating so you just lightly mist with water... though might weigh too much. Wondering also about using a think like silk screen stainless steel mesh so more EMF protection while gaining structure... especially with the UPHC metal fibers. Thanks for sharing!

[@B30pt87]

Why did you only fill it up to four feet? Is there a problem with filling the whole shell? (I want fire resistance, so it's important to me to have the whole dome insulated.)

[@AircreteHarry]

I advise you to listen to the full video again. I addressed what happened. The shell ends up being filled fully once the situation is considered 👍 I explained what happened & made sure to share it with everyone else by advising what to pay attention to - to avoid a similar hiccup.

Why not build your first hard layer on your first air form. Then put the large air form on top. Shoot the aircrete between. Then pull the air form and spray the stick onto the aircrete.

[@AircreteHarry]

Welcome to the channel 👍 I've done this already years ago. Check out my older videos in NYC.

[@oldmayyyte]

It looks like your aircrete didn’t hold under the weight in the gap. It’s seems to have settled out like dense concrete with all the air retained above

[@Ilamarea]

Should make the windows and doors part of the airform, where they just stick out.

[@extremebudget]

I am watching more of your videos. I'm definitely going to do a video on what you are doing. I have been thinking this way too. Have you heard of Ralph Ring? He made an geofriendly-like home in the 70s with a garden on top and naturally heated and cooled. Based off of Nikola Tesla's ideas. He also talks about free energy that is available everywhere. He talks about Air Wells too. I could send you links to it. Let me know. He talks about getting electricity from quartz, tourmaline and from other crystals, even from cement. I have made cement batteries and lit up some LED lights. I'm researching off-grid incinerator toilets that use HHO generator technology that generates HYDROGEN Gas from water to use. I recognize the potential in Aircrete and have been telling people about it for a few years. I am so glad you are doing this.

Very nice! I am waiting for Spring here so I can continue my experiments. Began a small 7 foot dome last year but nature did not let me finish. Curious, I can not seem to find fiberglass mesh up here. Any tips on where I can find it? The hardware stores here look at me weird when I ask for fiberglass mesh lol

Seems like you could get huge rolls of screen like you find on a screen porch, cut to fit and glue together with spray adhesive

[@Faithful_Tribe]

Could you do an arch between the layers-for the doorway? and do the fiberglass etc. for that internal layer? Seems like it would make the doorway process + filling- solid a little faster.

[@Faithful_Tribe]

An arch between-in addition to the exterior arch. Attached before the outer dome is inflated.

[@AircreteHarry]

I did something back in NYC that I will do again using Foam board.

[@boneman1982]

Why not make a door shaped form that has an airtight door in it, that way you could cut the hole for the door before you spray anything on it at all, insert door form and attach the air form to the door form, and then just spray right on to the door so you don't have to mess with adjusting thicknesses, etc.

[@AircreteHarry]

Yeah, I've done it already👍 That's what I am and will be doing with my future domes/builds. Been experimenting with a few ideas that have been successful. Are you working on any projects yourself this summer?

[@ericb2247]

i wonder if you could sew a 2" wide skirt to represent the edge of the door to the airform and use it as a 'dam' to actually make the area around the door super thicker like a continuous beam and hit it at an angle with the sprayer so that very little stucco covers the door. Then, just cut out the pattern with a knife

[@DocJaeBass]

I was wondering about something similar, then thought, there would likely be problems with filling the aircrete between the inner and outer shell with the very thin and weak airform at the door bursting from the weight of the aircrete which would naturally fill the void.

[@AircreteHarry]

It's posable but would be complex to make It would take a few prototypes to get right.

[@ericb2247]

@Jason Stanley i think deformation is the problem he already has and cutting through the thin stucco leaves a jagged, fractured edge. I was describing beefing up around the outer edge so it holds a cleaner and robust shape. I can see how what I said sounded like connecting both airforms with a strip of tyvek If he could sew a flap to the outer airform following the pattern of the door, then staple a strip of that flexible plywood to keep it formed right. Maybe more beefiness there might even help mount a door/window securely, which I'm a little curious about.

[@NomadJoe]

Welcome to the channel Dean, We are located in CO.

[@scorpio6587]

15:00 What if you kept the inner dome under pressure while filling the wall?

[@AircreteHarry]

I could not do that because the air would go into the inner and outer dome at the same time the way the pipes where set up. Also if you have an air leak from the inner dome it would make air pocket in the Aircrete and not set up correctly.

[@scorpio6587]

@@AircreteHarry I see. Thanks!

[@kenknutson1598]

If you were to put the seams on the inside of the domes before spraying, the dome would be smoother. It would also make it easier to peel the form off the inside.

[@AircreteHarry]

The seams for the air-form are on the inside. The seams for the fiberglass mesh are on the outside. The seams also act as a depth gage when spraying the cement mix.

[@kenknutson1598]

@@AircreteHarry sorry. I watched the video of pealing the form off the original cabin. I guess the mesh layer makes it look like the seams were on the outside. Filling the gap between two shells with an insulating layer is rather interesting. I continue to watch your progress, and wish I could play too.

[@salkjshaweoiuenvohvr]

Perhaps instead of using tyvek, use fiberglass cloth, inflate, spray fiberglass resin, cut your door frame, layer concrete?

[@AircreteHarry]

The cloth has to hold air. Fiberglass will not work.

[@salkjshaweoiuenvohvr]

@@AircreteHarry then perhaps you can still use the tyvek at the start, overlay the fiberglass cloth instead of the mesh, and spray the resin there? As you mentioned the Tyvek won't stick to it, and once the fiberglass hardens you will have much more control cutting your doors and windows as well as have a water vapor barrier. I'm looking closely at your innovations while checking out a few others as well. Keep up the excellent work!

[@parallaxical3067]

Hey Harry, it's Ernest again with more thoughts lol. So the doorway issue. How about creating a negative space for the door (or any portal/ window). I'm thinking wood frame, and plywood or something covering it. And it could be designed to be disassembled from outside. Basically all the screws are put in from the center, and the outside. And mark the form, so you know which side goes outward. Mark the slab where the door will be. So you can easily locate it. And after you spray the inner skin, place the form before inflating second skin. I think if it might help to leave the portal form in place until all of the outer pour is finished, and maybe until the center fill pour is done too. Maybe you could put a little doggy door in it, so you could inspect inside. Or maybe just a frame to hold a piece of the masonry board, and open through the center. Might have to use wide gorilla tape, to hold the tyvek to the portal mold. Or even cover the outside of the portal mold with tyvek. I hope it makes sense. I struggle with words sometimes, i could probably do a better job drawing a picture with crayon. And I'm not sure if any of this would even work.

[@parallaxical3067]

I had considered styrofoam, to fill the void. But the ultimate goal, is something reusable to match with your forms. And apologies if my ideas are bunk. My thinker aint so good.

Mesh sewing join could be a weak point, maybe use left over bits or just use strips of 6-8 inch mesh and overlap each joint

[@AircreteHarry]

Not needed the mesh is strong.

[@leoncryp8182]

​@@AircreteHarry I know the mesh is strong, but the sewing joint is a weak point. In construction when anything join together there is a needs to be a set length / ratio where it overlaps. that single strand of vertical sew string is weak point, i think your overlap 1 inch is when folded properly to the side is stronger then the single strand of string. Please do a simple weight tension load test. Make few 6x6" log say 4 feet length, with regular aircrete+additives and have the underside put mesh + 0.5" cement, then load it with weigh to find the breaking point test 1) control full mesh with no joints test 2) your standard 1 string sewing join and 1 inch overlap in the middle test 3) mesh with 3" over lap test 4) mesh with 6" over lap Note the overlap should not be in the middle, but slightly off centered as I assume you going to put a 6" wood board to spread the load, so it should be 3" off centered, as the edges of the board is the pressure spot and its at those 2 end point where it first cracks and break under load. Reinforce Mesh width maybe reduce all test to 2-3" strip wide instead of the full 6" wide (aircrete block size no change). so you dont need to load that much weight for your test. I think 6" wide Mesh with no cuts should be able to support your wight. Suggestion when you make your mesh maybe dont cut it out to shape first, as the top 1/3 of the arch has access mesh use that to make a larger overlap, and only reinforce the sew joins bottom 2/3 with more overlap on the sides, with access mesh trace the shape individually with spray paint then sew them together, then cut out the access leaving a large 3-6" overlaps, more work and harder to sew them together, Maybe its faster for you to just do it the normal way, then use the access cut out and add 3-6" overlaps to the joint, i think that would be the better approach.
