Well, if you can't eyeball it, you can use the string. Fix the string to the center of the room on the floor, bring the nail on the string up to the layer you're working on, hold the brick in place with one hand and score it in an arc with the nail on the string. Then you can chip the part you don't need off.

I had attended a workshop where we had to build two types of domes, one on a circular base and the other on a square base with pendentives at the 4 corners( to get a circular ring). For the latter, we needed a level tube to maintain the levels on all 4 corners, and most of us got it wrong. It's astounding to see these guys do it without any level instrument. Awesome!

I am from America and want to thank you for recording human history and skills. My FAVORITE part was when you taught me that DRY bricks are important. Yet the reason you earned my respect is you gave the REAL sciences info so we could test our brick with your density info. Yes, this was my favorite part. I have seen videos of "fake bricks in Asia, mostly from Chinese and Russians. Do you have a way you test your bricks for safety or quality? Will you teach others so they can buy safe bricks for their family? Having a wood roof fall is one thing but a brick dome is asking for death.
Oh what a skill to have...outstanding craftmanship alongside patience with each brick to lay in position. Perfection...100% ! 👍 Blessings to all. 🤗❤🙏🏴 UK
@@OccupyMars2035 I have seen some remarkable examples in Iran. These techniques could be seen from Rome to India, but very few have retained the knowledge.

Nobody here appreciating how precisely those craftsmen stay to the rise of their dome with no template? I think that inaccuracies strongly compromise the strength of this structure.
@Roderick storey Except in the foothills of the Himalayas, India is not famous for its snowfall. BTW, rooftops are different there. As for rain, it's a problem if the roof is flat. Here, it's a dome not a pool. Water flows naturally outside. A dome (or an arch) can't collapse. Its weakest point are the walls that take all the forces. Moreover, this method of construction is ancestral. If it didn't work, don't you think they would have done it differently? So strength for what? ==> For their needs. That's obviously enough
Pana Cotta he’s referring to the rise in each level being consistent, otherwise the compressive forces would not evenly transfer throughout the structure. But they do use a template, the string at center.
Id love to try seeing a couple of these done, challenging maybe but it looks pretty simple once its set out properly 👌 Some of the cuts could be measured and cut to create a better wedge but as long as its joints are full, an arch is self supporting. I built a voussoir arch and as soon as i pointed it i stood up on top of it to prove its stregnth. It was in my back gerden built on the ground and not on an actual structure.
the idea is to proliferate these techniques of construction and bring about a discussion in the mainstream discourse as an alternative for spanning roof.
Okay, watching the process with a keen eye i picked up a few things... 1, Before the first ring is complete, the corners appear to be built as independent arches, so those need no real assistance to be supported. (6:30) 2, Once the first ring has been completed, brick geometry then becomes far more important. (7:40) 3, The cement mix is also critical, it needs to be very adhesive, must harden reasonably quickly and not shrink too much when dry. (8:30) 4, I suspect the cement shrinking is part of the reason they render the top immediately while also spraying to keep it moist. (9:30) So why does it not fall in? Put simply, physics... The reason a single brick doesn’t fall in when being placed is the cements adhesion... The reason a whole ring doesn’t fall in once the cement is dry is because of geometry, the ring as a whole does not fit through the hole below it.
The west (assuming you are from the west) has strayed too far and slowly India too is drifting that way... luckily we still have some master masons who might be the last ray of hope and the custodians of invaluable traditional knowledge, that is mind-bending! What is really stroke-worthy is the fact that houses in the west are these days made like matchboxes with flimsy timber that will go up in smoke in a jiffy. Soooooo much needs to be done to keep it protected from the elements and termites and bugs and towards thermal insulation. They result in a very heavy Carbon footprint. Conversely, these traditionally build homes and structures are sustainable and eco-friendly. This might come across as an East v/s West run down but is only intended to say that we, in India need to cradle and protect this knowledge before it is wiped out.

What gets me is how the building supports the thrust forces created by an arch or dome. I see that the ring beam that holds the dome is made of concrete, while the rest of the building appears to be normal structural brick.

That means that technically, while the dome is an ancient building method, using it in this way is only possible in the modern day. Previously, the building would've needed massive walls to support the dome.
Brilliant work by very skilled tradesman. Lots of comments about how the bricks stay in place as they are being laid ! It's a combination of many things but the key here is very dry porous bricks and wet sticky mortar. If you laid this brick normally on a wall and waited 30 seconds or a minute and tried to pick it up you would struggle as it would be slightly stuck. As the dome goes up its shape and the forces take care of the rest. I really want to build one now, I would love to spend a week with these guys.
For each course (ring) of brick the wet mortar has enough adhesive strength to hold the bricks in place until the ring is complete. At that point, each brick course is acting as a compression ring with the forces pushing outward. The lateral forces are strong enough to overcome the gravity load. When the entire dome is complete, the rings act together and the forces are distributed in all directions. Very impressive and economical to build, although I'm a little surprised that they rely on running bond for the brickwork - headers would make the whole thing easier to construct.
@Smile Architect here w. 40+ years experience . If you want to see a real magic trick check out how the dome at the Florence Cathedral was built. Double shell brick masonry built without formwork. You can take a tour and climb between the two shells all the way up to the cupola on top. The cupola (they called it a lantern) is like a cork in a bottle and it keeps the whole thing from collapsing. Long span Renaissance magic by Brunelleschi.
in the days of prefab and composite materials I appreciate these craftsmen taking the time to build this. Time will tell which dome will last longer. edit: even more blown away when you realise this is not going to be a spiral
God has provided them the switch to turn ON/OFF Gravity. jokes apart, this is called talent, that is polished by lots of hardwork. Experience matters a lot.
This is the same technique as Brunelleschi’s dome for the cathedral of Santa Maria del Fiore in Florence. He built two dome, one inside the other and used herringbone brickwork, an innovation. Impressive how the men in this video build their dome without any such additional techniques!
This is the first time I have seen anything like this and it's simply amazing to watch. Like most I can't seem to grasp how the individual bricks don't fall inwards/downwards while it's being constructed but seeing is believing, Wow! Thanks for sharing this technique🥰
If hundred people try to enter a single door all at once, no one will be able to enter through the door. Similarly, all bricks are trying to fall all at once but none are falling. It is the gravity itself which is holding them up.
no engineering PhD , no CAD design ,no stress analysis simulation , our ancients figured out HOW to get things done and "WE" are bound to be AMAZED 🙏🇮🇳
@@shiddiqalminsyawi1195 You are un uneducated moron without any clue about buildings but quick in commenting! There is a ring anchor reinforced with structural steel around the dome. This is earthquake resistant and the dome will not collapse as long as the ring is not broken.

Just why each individual brick stays in its place without any kind of support is twisting my brain into a painful knot. I saw it happen but simply do not understand. I couldn't be more amazed if this had been performed on the "Fool Penn & Teller" show. True craftsmanship. Thank you for documenting the skill that could not be believed without seeing.
For those why the structure just doesn’t collapse under its own weight Its because after the cement dries with the bricks the entire structure becomes the equivalent of a large cement panel or block, the bricks also stay together thanks to the interlocking placement which exerts compression to the outer wall a bit like the structure of a dome but in this case it’s flat, but the same principles apply
@@nightshift2780 I agree. This construction should be outlawed as a profligate and wanton use of cement. Cement production is highly damaging to the environment. Does anybody want to join me in writing an appeal to the country's authorities with a view to stopping this type of roofing?
I've seebn videos of almost the exact same thing done in Mexico, the main differences I see is that in Mexico it looks like they you plaster de Paris, for mortar and it's very thin. I believe the Mexican way is a little faster and probably just about the same in strength, because though the mortar may be weaker the joints are tighter. Either way, beautiful work. Being a mason myself I'd like to try it, but where I'm from in the states you can't get brick like that, and no way would it ever get past code.
Bricks maybe costlier in America but Timber is cheap, quite opposite here in India. Econony matters so different places has different building techniques .
For the people who wonder about the strength of the roof. Its not as simple as seen in the video. All the bricks are places at very precise angles making a low ark dome. This structure is in use since long in ancient buildings. Very stable and strong. Dome shape structures are very common in Indian architecture. It is modified form of same technique.

@@seetu1500 There is no concrete being used in the build of the dome, but your point is not wasted. If only they would include some concrete ballast in their mortar, it wouldn't be so wasteful of the cement to which you are referring. Oh and the roof would be stronger.
I like the fearful comments. No clue about buildings, but commenting. There is a ring anchor reinforced with structural steel around the dome. This is earthquake resistant and the dome will not collapse as long as the ring is not broken. This is one of the best constructions to resist long time as the dome even may be shuttered, it will just settle.
@@mucsalto8377 I'm sure the dome could collapse in certain instances without the ring being broken. If the ring was deformed a bit and the mortar between the bricks was sufficiently crumbled. That being said, many common building techniques do not endure earthquakes.
Incredible craftsmanship, they are highly skilled at what they do. The end result from inside looks beautiful, such a nice change to a normal white ceiling.
There is a Catholic Church, the Basilica of St. Lawrence, here in Asheville, NC that was designed and built by Guastavino. He came here to help with the building of the Biltmore House and Estate. There are no steel supports at all in the construction. Beautiful inside and outside. He died here in Asheville in 1908 and is buried in a vault within the Church.
H DB okay, you’re saying that buildings collapse. Yet you have no real reason to give why these would? Other than some gut feeling that it’s not strong enough? I just think that you don’t understand how strong a dome like this can be and so you try and act like you know more than you do about a bunch of unrelated stuff.
@H DB you talk about weight--in the video they show the roof supporting three or four men quite easily. If it holds up a man, how could a jackfruit break it?
@@jmadventures9830 In a earthquake, the only thing that will keep the bricks from falling is steel reinforcement. It could last 500 years or drop tomorrow. Good luck!
TRU Dat These kind of structures are being built from centuries when there was no steel reinforcement in use....and the place where they are built in India lies in “seismic Zone-4”...they are engineered to last long

Unbeliveable, mind-boggling skill! Wow, I am blowed over by this video. Master Art. I have not seen anything more skillful than this. One mistake, they will all be under rubbles.
I just can't understand how would bricks stick to the cement mix without a vertical support, at least till it dries? 🤔. If one circle is completed, may b bricks wouldn't have enough space to dislocate from each other but till that circle completes only thing which holds bricks are wet cement mortar.
The mortar has to be just the right mixture of stickiness and stiffness. The bricks need a slightly rough surface (for example made with sand in them). The mortar must cure properly, NOT dry out, otherwise it crumbles. I have seen an arch made using concrete blocks, but it was not very wide.
These brick are light compared others and also very dry. As soon as you put the mortar on, it starts to pull out moisture so you must be fast when placing the brick. It also creates a suction, like when you step in thick mud with your shoes on. Plus once you complete a row, it then has binding strength. The type and consistency of the mortar is important also depending on joint size. There are other factors I'm sure, but the main thing is that it works. The ones done in Mexico look like they're done entirely by eye, no tape, no strings, nothing, just put em up. This is what amazes me.
It's possible sir we can calculate tensile stress and compressive stress on that dome even my college also constructed like that my you can a check it for knowledge purpose my college name is Andhra University bachelor of architecture department
The guy in the thumbnail had also came to my site and worked... It only depends on him and his skills his parents did that... And his grandparents too...! And it depends on their observation of the first Corner and the first brick they put one and then their slice on bricks matters...

At that point, each brick course is acting as a compression ring with the forces pushing outward. The lateral forces are strong enough to overcome the gravity load. When the entire dome is complete, the rings act together and the forces are distributed in all directions.
Very impressive and economical to build, although I'm a little surprised that they rely on running bond for the brickwork - headers would make the whole thing easier to construct.
@Smile Architect here w. 40+ years experience . If you want to see a real magic trick check out how the dome at the Florence Cathedral was built. Double shell brick masonry built without formwork. You can take a tour and climb between the two shells all the way up to the cupola on top. The cupola (they called it a lantern) is like a cork in a bottle and it keeps the whole thing from collapsing. Long span Renaissance magic by Brunelleschi.
Where I found there Mason plz tell these ph. No.
@@billdek thanks. It is refreshing to read an informed comment here.
Wow...! nice technique... should get recognition from government...
They should apply for patent ... and become brand..
In Azerbaijan all old houses are built this way.
You guys should be proud of what you are doing! Very marvelous job that you are doing! Thank you.
in the days of prefab and composite materials I appreciate these craftsmen taking the time to build this. Time will tell which dome will last longer.
edit: even more blown away when you realise this is not going to be a spiral
Skills. Ancient techniques that have proven themselves. Much ancient knowledge was lost during the Dark Ages or who knows where we would be now.
Visit india for ancient practices....😁✌😁
@@helpinghand862 The Arabs were the most advanced and then they went backwards. They still haven't caught up.
@@helpinghand862 I'm not going to India any time soon, but I get updates about it from the guy that runs my liquor store.
Fasinating to watch! Those gentlemen are highly skilled craftsman! I salute them!👍😄
okay, but how do you turn the gravity off?
They are in moon
@@sajinraj2250 haha😂
God has provided them the switch to turn ON/OFF Gravity. jokes apart, this is called talent, that is polished by lots of hardwork. Experience matters a lot.
@Smile did you see the video? They build a mall roof in one day. But you have your own opinion and comment !!
Gravity doesn't exist 😂
This is the same technique as Brunelleschi’s dome for the cathedral of Santa Maria del Fiore in Florence. He built two dome, one inside the other and used herringbone brickwork, an innovation.
Impressive how the men in this video build their dome without any such additional techniques!
Thank you sharing knowledge. Liked it.
Thought I would just watch a mnute or so. Not possible. Absolutely mesmerising!!
OSHA: *heavy breathing*
J M the engineer in me would not want to be anywhere near these during an earthquake.
This is the first time I have seen anything like this and it's simply amazing to watch. Like most I can't seem to grasp how the individual bricks don't fall inwards/downwards while it's being constructed but seeing is believing, Wow! Thanks for sharing this technique🥰
If hundred people try to enter a single door all at once, no one will be able to enter through the door. Similarly, all bricks are trying to fall all at once but none are falling. It is the gravity itself which is holding them up.
Literally no one:
TH-cam at 3 a.m.: Hey, you wanna see people laying bricks?
Heck it's 3:29 am as I read this
2:55 am for me
I am seriously impressed!!! How does a brick even hold at that angle!?! Thanks for sharing!
no engineering PhD , no CAD design ,no stress analysis simulation , our ancients figured out HOW to get things done and "WE" are bound to be AMAZED 🙏🇮🇳
Got earthquake it will be disaster for our family. Safety first
@@shiddiqalminsyawi1195 Brick fall on had, disaster for him.
@@shiddiqalminsyawi1195 You are un uneducated moron without any clue about buildings but quick in commenting! There is a ring anchor reinforced with structural steel around the dome. This is earthquake resistant and the dome will not collapse as long as the ring is not broken. This is one of the best constructions to resist long time as the dome even may be shuttered, it will just settle.
@@mucsalto8377 This construction should be outlawed as a profligate and wanton use of cement. Cement production is highly damaging to the environment. Does anybody want to join me in writing an appeal to the country's authorities with a view to stopping this type of roofing?
These people are real engineer.. Hats off 🧢 lots of love and respect.. 🙏
Always appreciate the value of genuinely skilled workers. My thoughts however are how this type building can stand during and earthquake.
Just why each individual brick stays in its place without any kind of support is twisting my brain into a painful knot. I saw it happen but simply do not understand. I couldn't be more amazed if this had been performed on the "Fool Penn & Teller" show. True craftsmanship. Thank you for documenting the skill that could not be believed without seeing.
I was thinking exactly the same.... Surely the cement isn't enough to hold it
That's impressive , most modern day brickies couldn't do that I'm sure
They do this in Mexico alot I've seen it in several towns I've visited
It's most likely the mortar their using
Super amazing marvelous... Hatsoff to this skilled aretisian... No words to express...cherish these artisans...
We already have this technic. 150 year old in my town.
Very interesting and informative.one of the best craftsmanship showing video on the TH-cam
VERY VERY IMPRESSIVE ~ AND QUITE BEAUTIFUL.
Thank you so much sir for making shallow dome technology available to many through your efforts of simplification here and on your website :)
For those why the structure just doesn’t collapse under its own weight Its because after the cement dries with the bricks the entire structure becomes the equivalent of a large cement panel or block, the bricks also stay together thanks to the interlocking placement which exerts compression to the outer wall a bit like the structure of a dome but in this case it’s flat, but the same principles apply
Not entirely flat mybe, well it's look a bit like dome but rather flat compared to its real appearance.
@@workinprogress6504 The trick is to use a reverse fish-eye lens when filming. ;-)
@snowman - right, and there's also ZERO support underneath.. not a building I would prefere to walk into. Forget it
@@nightshift2780 I agree. This construction should be outlawed as a profligate and wanton use of cement. Cement production is highly damaging to the environment. Does anybody want to join me in writing an appeal to the country's authorities with a view to stopping this type of roofing?
@@happyharry5153 in what way does the production of cement damage the environment? You must be joking around because the entire world uses cement.
Very good brother your team is a wonderful one. I like your art, I love it
I've seebn videos of almost the exact same thing done in Mexico, the main differences I see is that in Mexico it looks like they you plaster de Paris, for mortar and it's very thin. I believe the Mexican way is a little faster and probably just about the same in strength, because though the mortar may be weaker the joints are tighter. Either way, beautiful work. Being a mason myself I'd like to try it, but where I'm from in the states you can't get brick like that, and no way would it ever get past code.
Bricks maybe costlier in America but Timber is cheap, quite opposite here in India. Econony matters so different places has different building techniques .
Try baking them...
Excellent craftsmanship gentlemen. Well done.
awesome amazing mind-blowing respects from Pakistan
Seriously impressed! Great work! respect to you for a so beautiful results.
Interesting, using bricks to hold all the mortar together...
Yes
Fantastic work, guys! Thanks for posting this. If I ever get the chance, I'll try it. You should build dome homes too.
For the people who wonder about the strength of the roof. Its not as simple as seen in the video. All the bricks are places at very precise angles making a low ark dome. This structure is in use since long in ancient buildings. Very stable and strong. Dome shape structures are very common in Indian architecture. It is modified form of same technique.
SUPER!!! Szacunek dla murarza, to jest mistrzostwo.
I'M not sure whether I'm not understanding or I'm just refusing to accept it, that this is actually done by hand.

@@happyharry5153 It uses 10 times less concrete than regular rcb roofs. Are you 9 years old sweety?
@@seetu1500 There is no concrete being used in the build of the dome, but your point is not wasted. If only they would include some concrete ballast in their mortar, it wouldn't be so wasteful of the cement to which you are referring. Oh and the roof would be stronger.
I fully understand why it not collapse! brilliant idea! Thanks for upload this video.
Not confident ...nver forget,the earth is always active
Precisely. Death Trap during an earthquake
i was thinking same
Yeah, I'm interested in what kind of loads it can bear, and how long would it last for.
I like the fearful comments. No clue about buildings, but commenting. There is a ring anchor reinforced with structural steel around the dome. This is earthquake resistant and the dome will not collapse as long as the ring is not broken. This is one of the best constructions to resist long time as the dome even may be shuttered, it will just settle.
@@mucsalto8377 I'm sure the dome could collapse in certain instances without the ring being broken. If the ring was deformed a bit and the mortar between the bricks was sufficiently crumbled. That being said, many common building techniques do not endure earthquakes.
Incredible craftsmanship, they are highly skilled at what they do. The end result from inside looks beautiful, such a nice change to a normal white ceiling.
Very popular in USA introduced by spanish architect named Rafael Guastavino in 1900s
There is a Catholic Church, the Basilica of St. Lawrence, here in Asheville, NC that was designed and built by Guastavino. He came here to help with the building of the Biltmore House and Estate. There are no steel supports at all in the construction. Beautiful inside and outside. He died here in Asheville in 1908 and is buried in a vault within the Church.
@@larrykeenan598 wow! its such a wonderful connection knowing that he is now at peace within his own masterpiece! thank you for sharing this story.
Love to watch a professional tradesman work. Amazing.
Impressive skill. I don't know how they make it crown accurately.
H DB why do you think you’re smarter than them?
@H DB that what happened to your head?
@H DB I doubt a bridge collapsed due to coconuts and jackfruit 😂
H DB okay, you’re saying that buildings collapse. Yet you have no real reason to give why these would? Other than some gut feeling that it’s not strong enough? I just think that you don’t understand how strong a dome like this can be and so you try and act like you know more than you do about a bunch of unrelated stuff.
@H DB you talk about weight--in the video they show the roof supporting three or four men quite easily. If it holds up a man, how could a jackfruit break it?
Most satisfying thing I have seen in Months 👍
I can just imagine trying to get a building permit for that here in canada.
No kidding lol
Lol
I'm waiting for the video of the collapsed rubble after the next earthquake!
not a chance in he double toothpicks
i hate the frigen government so damn much
Wonderful craftsmanship. A lesson for builders in the West.
Looks like a nightmare during a earthquake.
my woman is saying that but I think it should be ok
@@jmadventures9830
In a earthquake, the only thing that will keep the bricks from falling is steel reinforcement. It could last 500 years or drop tomorrow. Good luck!
TRU Dat
These kind of structures are being built from centuries when there was no steel reinforcement in use....and the place where they are built in India lies in “seismic Zone-4”...they are engineered to last long
Keep it Up . One day rohtak dome will become famous all over the world. Like our ancestors, which was one of the best engineers in the world 🇮🇳❤️👍

I feel like such a chode... I cant even cut my lawn without my DieHard's. This guys building a structure barefoot. SMH!!
Unbeliveable, mind-boggling skill! Wow, I am blowed over by this video. Master Art. I have not seen anything more skillful than this. One mistake, they will all be under rubbles.
I just can't understand how would bricks stick to the cement mix without a vertical support, at least till it dries? 🤔. If one circle is completed, may b bricks wouldn't have enough space to dislocate from each other but till that circle completes only thing which holds bricks are wet cement mortar.
The mortar has to be just the right mixture of stickiness and stiffness. The bricks need a slightly rough surface (for example made with sand in them). The mortar must cure properly, NOT dry out, otherwise it crumbles. I have seen an arch made using concrete blocks, but it was not very wide.
@@paullangford8179 very interesting construction. I think even igloos are built similar way?
@@paullangford8179 cure like ham?
These brick are light compared others and also very dry. As soon as you put the mortar on, it starts to pull out moisture so you must be fast when placing the brick. It also creates a suction, like when you step in thick mud with your shoes on. Plus once you complete a row, it then has binding strength. The type and consistency of the mortar is important also depending on joint size. There are other factors I'm sure, but the main thing is that it works. The ones done in Mexico look like they're done entirely by eye, no tape, no strings, nothing, just put em up. This is what amazes me.
It's possible sir we can calculate tensile stress and compressive stress on that dome even my college also constructed like that my you can a check it for knowledge purpose my college name is Andhra University bachelor of architecture department
Incredible watching such skill tradesmen work their art!
How are the bricks not falling without support during laying?
HOW?
Its called physics... in general,
th-cam.com/video/xNDppVTVUss/w-d-xo.html would explain
They want to fall out, not down -see 'domes wiki' or something- soo.. your answer is ringbeam.
The guy in the thumbnail had also came to my site and worked... It only depends on him and his skills his parents did that... And his grandparents too...!
And it depends on their observation of the first Corner and the first brick they put one and then their slice on bricks matters...
Oh ok.
Good work...thank you guys for promoting such kind of skills which were lost in time ...if psbl provide training and spred knowledge
god bless you....
I suppose earthquakes are very rare in this region?
Exactly Right
No. Rohtak is in sesmic 4 zone i.e high damage risk zone and this region got 13-14 earthquake in lockdown period 2020 only with most epicenter in Rohtak itself.
I wish I had HALF the skill these men have...
you probably do but just on www things ...
