I really don't understand modern people neglecting to use lime wash. It's aesthetically pleasing and it protects the cob from the elements.
yah i thought so too, even firing calcified brick too..

So is two bowls of green olives.

CHEVERE
Why not have a motorized track to pull all of that mud up? Seems time consuming and a lot of effort to throw little chunks of mud
I haven't seen it done quite this way before, intriguing, thank you.
Do you plaster over it?
Старый, добрый саманный дом!👍 Летом прохладно , зимой тепло. СУПЕР!
Going back to basic cool idea ! This was how we used to build houses in Ethiopia!

This is both dangerous, time consuming and impractical for certain locations. There is a reason we use the materials we do today rather then this crap.
@@rage9278 You're just jealous 😆 get well soon.
@@rage9278 Some of the longest standing homes around are cob you dingus
People of Central Asia build home 1000 years by this style...its warm in winter and cool in summer!
Dilshod Mirzaaliev Eastern Europe to!😂😂 but for them is NEW !
My village still has few houses of mud
Yes I remeber people in Afghanistan also stamping on the mud with the straw haha.
literally everyone in the world has been doing this. In the midwestern united states they used to make cob and sod houses in the 1800s
Begon Genesis and before that, native americans in the southwest used earthen materials as well. its ridiculous for anyone to claim the oldest building material in the world lol
Seems a very dry mix with less structural adhesion, but probably due to the ply shuttering which will not allow drying until removed. Mixing cob (or bauge as it’s French) with a digger in a pit or skip would be quicker and more efficient. No mention of the need to meet French legal thermal requirements with that thickness of wall. See the UK/French CobBauge project which meets UK and French building regulations using a composite low carbon structural/thermal earthen material.
Nice!! Well done!
A cement/concrete mixer, a jackhammer and a simple conveyor belt would make the job much easier.
yah so would have just ordering lumber and hiring the local framers
These techniques: to build with mud. (adobe) are very old, the conquerors found it in the ancient cultures of America. the preColombines already had it, it is not a modern thing, but it is the best invention.
Uzbek style, cool in summer and warm in winter, most importantly clean air and good health
Interesting technique of making your soft bricks to pack. I'll try it on a small wall of the shed. Looks promising.
Человечество возвращается туда с чего всё начиналось. Новые технологии не к чему хорошему не привели.
Бизда пахса дивол дийишади гап йук лекин!!!okey👍
Европада пеноблок, газоблоклари бошидан утгазип, хатоларини тушиниб бизнинг пахсага мехри пайдо булибди.
Бизлар эса ахмоклик килиб энг экологик уз технологиямиздан бош тортиб пеноблокдан куриб бошладик!
Super nice house!! Good work! Thank you
:O! woah. This is way different than rammed earth. I like this variation.
yea no cement at all
I get the feeling that a lot of sustainable building is really relearning what we did a long time ago but with a modern twist to the method. I mean, that cob could be mixed in a cement mixer. Instead of straw, they could use plastic strands reclaimed from discarded bottles. For additional binder strength, a little cement goes a long way. Instead of manually throwing it up, a forklift or a manual hoist could work as well.
I get that they're doing it this way to emphasize the sustainable, low-emissions aspect with basically dirt-cheap costs in terms of material, but in terms of labor, all the cost savings go out the window. If you can show it can be done quickly with little labor through the use of modern machinery, be strong and consistent enough to hold up to building codes, and still be economical overall, then you have a system that would be a viable, competitive option to be considered for use.
It's the inconsistency that's really the problem here: no architect or engineer would check off a design that uses an unknown or inconsistent material because if that wall failed, breaks, or kills someone due to inadequacies in the material, the legal repercussions could fall on them just as hard.
First off you wouldn't use plastic it wouldn't bond with the clay you could use some concrete in the mix and ram it and get a consistent compressive psi rating adiquite for even multistory construction I would suggest an electric mixer but volunteer labor is free so it doesn't seem to affect their costs...
Of course there are volunteers to be (ab)used 😾
Nice,,, take me back to oldday , where we were building our homes with sand and hatched coconut leaves.. 🤝🤝
It seems you need to let it dry out before the finish process. Which is like waiting for adobe bricks to dry out. But this way the mud is more pliable so can fill every little crack. Shuttering the boards is like rammed earth or a hemp mix.
So, is this style of construction seen in medieval architecture from the region as well or is this a modern application of various techniques?
Excelent Job thanks for sharing
How long do you let it dry out before you start the finish coat process? Do you fill all those exterior cracks with the first finish coat which I guess is thick?
Assolutamente bellissimo. Mille grazie per la condivisione!
in romania i see this stuff till 2000 in the villages , more exactly in the moldovian , or eastern areea of romania ,Europe
Que bello trabajo y que personas tan lindas.
c'est très bien! merveilleux.
What can be the finishing materials here to give a clean finish as well as which can reduce the impact of rain water on wall?
The best way to reduce pollution 😊
Excellent work
It's good for countries where the weather is moist?
i wonder wouldnt it be a lot less labour intensive to make wood panels, put them horizontally and fill with cob and then erect and screw them together?
Very very good job . Thanks bro .
Like houses in Kyrgyzstan! There are, 3 tipe of tehnologies we build houses, 1 brick, 2 ( basma) like on the video and ( sokmo) when wet dirt pressing with device made from wood. We begin to forget build houses from earth, build our houses with urban materials, trying to be similar with evrope, at the same time evrope build this old tehnologie beautiful eco houses!
A lot of cultures in the world independently developed cob houses. It's been a traditional type of building in Britain right up until the last hundred years and is seeing a resurgence.
Epic! Merci
Now that is some hod tending.💪🏻😀✌️
Great going. I wanted to do such a thing.
Дуже трудоємкий процес... Ручна праця дорого коштує...
Проте еко того варте...
Это самая экономичная стройка дома тем более чисто экологически
И всего-то пятьдесят студентов месяц на стройке провели, практику закрыли. Дешево, че.
How do you get the cob to not crack when it dries? When I build things with cob, the walls crack.
Super 🙏👍👍👍👍👍👍🌹❤️❤️
very good friends.
Looks like they are not compacting it enough... The tighter the compaction the more stable the wall will be..
You're awfully critical...
@@callmeswivelhips8229 , no.. just seen these builds many times..i live in the desert southwest..there are quite a few of these..and if you don't pack it well it will become crumbly.
@@dfbess I understand if you have your own experience with it, but all kinds of cultures build these type of structures all over the world, and they all have their own recipes, and maintenance schedules to go with those recipes. This building type is extremely cultural. It seems short-sighted to so judgemental of their method if you don't know much about the cultural surroundings to it. Not that I'm saying you're wrong. But I question how much of an expert you really could be on these people and their way of life.
It's always good to have differing opinions to make good sound weighed decisions upon.
Makes sense kind of a rammed earth concept, I think it's not compacted to give it that texture look which I think is what shuttered means, I clicked on it to find out
Этот важный технологии в Узбекистане до с тех пор в моде
Узбеклардан хали булар куп нарса урганишади😊😊😊
херб какая-то. особенно порпавился способ доставки кирпичиков из глины на второй этаж, поштучно
Amazing
Fun @ work 😀 i love it!
Мои предки так строили до 20века😄
Хотя соман хороший материал. У них нет такой зимы как у нас
Из самана можно строить где хочешь. Главная проблема его высушить .
❤️ this video
In my country the soil is salty would you be affected if you build a house in the same way
How do you get your Gage good adhesion between layers?h
Hey now, that's the last straw! Nothing added to the mix besides straw?
Very nice.
Sehr gut
As a natural builder, primarily cob, this seems to be a strange mix of cob and rammed earth without actually ramming the earth or applying cob as its traditionally applied, my questions is with all of the thousands of seams left un touched, how do you prevent seismic fracturing or simple adhesion release once the cob is dried?
My thoughts exactly. They are just hoping that friction and water bonded the natural clay.. that whole structure is going to have pieces break off and cause damage. I genuinely hope a wall doesn't collapse on anyone!!!
ye
hopefully there's some kind of ram we're just not seeing
Ваше новые технологии наши старые технологии
африканцы ахереют с этой технологии. зачем они бегут из африки во францию,чтоб в таких же землянках жить?))))
@@vladplatov9577 Ха ха ха. Проморолик для Африки и снят, наверное.
@@vladplatov9577 я живу на таких домов зимой тепло , летом прохладно 👍
Это не "наши" и не "Ваши" технологии, это умные технологии, им тысячи лет.
so true!
Самое главное экологически чистый внутри воздух другой летом в жару прохладно зимой тепло
Еs to es la arjitectura esta buena i muy barato por materiales super
Старый добрый саман))) только технология чуть изменили)))
Cob should be called "composite adobe" to make it sound more modern
We have this kind of buildings in Cyprus since 1930-50 some of them still stand today but you will learn soon you should have build your foundation longer and higher cause this mud when it rains for extended period soaks up all the water and shifts. 2-3 times and building collapses. Every time we have a lot of rain news outlets in Cyprus say bla bla bla this mud house collapsed and killed 2 elderly etc.
If you put on foundation plastic or bitum sheet then build walls, walls will not be soaked in raining season.
Plinth beam is must for safety.
Since you're shuttering the walls and Hemp is available in France wouldn't hempcrete with lime be easier and more energy efficient?
Cob is much more energy efficient than lime / concrete, which need great heat/energy to manufacture... and are a limited resource... not to mention the carbon miles to get them to site. The material for cob usually comes from the building site or its neighbouring area.
அருமை very good
In waziristan and tribal areas still we have homes made on same concepts..
This may seem like a silly question, but, can you mix linseed oil and peppermint oil to seal the wall and repell rodents? Or can you mix a soupy slurry of peppermint oil,straw and clay to stuff the walls to deter rodents?
Lime works well to repel rodents. However, in the USA, you'd be required to have a perimeter foundation 3'- 4' deep, plus cement up the wall, I think, at least 3' would be advisable. So, there is quite an expense there but... then youre on solid ground (pun ntended) to finish your project....
Also, in the USA, more into rainy/snowy areas in the north, you'll have to cement the walls, at least the OUTSIDE.
If building a strawbale house & you want plaster board walls INSIDE, you have to know WHERE, EXACTLY, the 4' sections of plaster board will meet & place short 2x4 pieces "through the wall" at the 4' wide mark to nail/screw the wall board to. This is more labor intensive & slows the process down. Also, IF the bales will be bearing the roof load (not a wood frame job), then the building will have to have time to settle (6 months I believe), BEFORE cement plastering the walls, or anything affected by the settlement. But, this gives you plenty of time to get your floor, etc, done inside........
@@ohwhatelse cement plaster on a straw bale house sounds like the dumbest thing to do. Strawbales with cob walls are meant to breath, but the can't with cement. Lime would be a better idea.
that is cool
verry very COOL
in Central Asia this ancient technology is called pachsa

But how to protect it from the outside from the rain?
я сделал бы закругленные углы - это очень интересно смотрится и очень приятно глазу
What is the life of this house? Any idea?
@zeeshan niazi. The houses normally are not made up of cob but of clay, that's why theres a problem. Moreover, the house dont have good hats and boots.
This is the Future healthy and dry
Ломпач ето отлично! ==))

I'm so glad that this isn't one of those hippy cob houses
This is advances or super cob house building thanks for putting it on you tube for us
I am interested.But I learn to your experience.
Таза экологической уй не деген енбек керемет
После замеса глина с соломой надо надо сверху накрыть соломой и оставить хотя бы на сутки, ийы қану керек, доводить до кондиции, после этого замес будет эластичным , плотно ложиться, это древняя технология, зимой тепло летом прохладно, эко чистый, человек в таком доме не болеет, аура хорошая.
Loved the construction. Anyone in India doing this, I will be keen to build a small house for me.
Ashish Sahu your kidding right ?
@@rage9278 I was not. But now i am Keen why you suggest so
Wahaha is super. but in Uzbekistan there are a lot of such houses.
Базар жоқ
you got the healthiest areas to live
How long will this building stand?
The oldest cob house is 10000 years old
Вижу свой кишлак:) мой дом тоже из глины.
Guys what about when it rains? would rain damage it? you know its clay and straw rain decays it? or it becomes water proof?
Rain does not have much effect. Theres a reason many cultures from ancient times have been using this tecnique for building shelter. To prevent bad effects from rain, they use stabilisers - wheat husk, straw(as u mentioned), lime, cow dung, and maybe more options too. Ancient Egypt and Mesopotamia used this method too, and they even plastered the walls for more efficiency. But every culture differs cause of their location. In Japan wooden houses is the most common because of its lightweight since natural disasters happen often. Some Asian cultures uses bamboos too
What's the solutions for rat attacks on wal
And I think I’ve seen a wide clay wall!
hah! How cute!!
В средней Азии всю жизнь так дама строили
There are building research establishments which do seismic stress testing - it would be interesting to see how these particular constructions would compare to a cob construction built with traditional/current cobbing techniques. I would expect very poorly. ...Not to mention that appearance-wise the gappy walls make me think of a shoddy concrete shed wall made with rough boxing and poor quality concrete which is crumbling - contrast this with to attractive hand sculpted cob or layered rammed earth walls.
I don't see any reason that shuttered cob couldn't work well, IF it was pugged and stitched properly, and only used in small sections - e.g. a vertical piece of similar bulk to a horizontal lift - it could enable you to work in awkward vertical areas and make sure you don't bulge the wall wider than a width you need to keep below for some reason (as you can with rammed earth)
It would enable you to build faster and further than you do working in lifts, because you wouldn't need to wait for the lower lifts to dry as hard before continuing upwards, BUT I would be concerned that building larger areas in one hit would lead to cracking and shrinkage due to the whole thing drying and trying to shrink in all dimensions at once. What you would gain in speed, you could pay the price for in quality and longevity.
Rammed earth gets its textural consistency from downwards and horizontal pressure (the ram and the shutters) filling out all available space. Cob gets it from making sure each part is good before continuing - people seeing and filling and stitching gaps during construction. If you're only lightly stamping cob into boxing (as opposed to ramming earth) you're only seeing the top surface and not seeing the gaps you're leaving beneath your current layer, because it's concealed by the shutters.
If you're leaving gaps and crack (as can be clearly seen in the end result in this video) then you're leaving internal flaws and weak points in the construction, and rough edges which can catch water and wash away material from the outside (I'm thinking of old earth brick walls I've seen in central Europe, being eaten away by the weather)
Ekan Vitki Well-said points. So far, regular cobb seems to be the most appealing for my own near future building projects. Have you any sources you can suggest for research/learning?
@@YountFilm For sure!
I would definitely recommend Becky Bee's excellent book:
