*NEXT* Rammed Earth House Part 1

[parkert51]

Whats the cost compared to traditional building?

[SacredFireLodge]

My 1 question is this, how do you find a loan institution that will finance a home like this or a Qaunset hut? Would love to find out as we are putting up a Q hut to live in... Thanks to anyone with info about this...

And of course there is the no formaldehyde, benzine, styrene, heavy metals, pesticedes, etc you will be exposed to!

[moles2000]

This is a beautiful home. Unless you have been in a finished home like this you have no idea how wonderful it feels. And the benefit of this type building will last many lifetime. In many parts of the world you would never need any heating nor cooling. Is not that green enough for you doubters? Cost per sq f means nothing in the lifetime of benefits.

So thats pretty neat stuff but what is the cost per square foot for that type of construction? I know that depends on many many things but percentage wise versus conventional construction. Nice looking stuff though.

they make thicker walls so probably they use same amount of cement :( that is fail. SCAM!

[aaron4820]

@vaidotas86 They are using 10% cement as oppose to 30% cement, so unless the walls are 3x thicker, which it isn't, it wouldn't use the same amount of cement. On top of that, they are using earth found on site, which saves on what would have been the other materials and its transportation costs, this would be more energy efficient as well as cost effective compared to conventional concrete, what do you mean by scam? planet earth trying to scam you to use their material for free?

[vaidotas86]

@aaron4820 "we using a mixture of gravel and water and cement" they sad... so same stuff as for cement, I can see that they are creating much more thicker walls (more than 3k) in comparison of normal cement wall (10 - 20cm of cement is enough for one floor house. So in result they are using same amount of cement, 3x times more gravel, 3x times more sand and using a lot of energy while packing that stuff. So it is at least 3x times scam. Its is terrible technology and not eco friendly at all!

Why don't you call it rammed concrete? This is a disgrace to true rammed "earth". Neat concept but I'm upset. You want a tough wall? try mixing fly ash in. It will take a hammer blow plus give some insulating quality you wont get with cement.

[bobdeeks]

Using clay would certainly reduce costs and greenhouse gas emissions as well as lower the environmental footprint but due to the snow load and seismic standards we could not get our engineer to accept clay as the binding agent. Good suggestion though.

The walls are engineered to resist lateral and compressive loads and are not impervious to a direct blow such as a sledge hammer; even a high MPA concrete wall will chip if hit in such a manner.

The material is naturally beautiful - why not let it speak for itself instead of trying to form it into cheezy mt panoramas? My bet is someone paints those over before too long...

[fieldofrob]

HOPE YOU DON'T THINK IM PICKING HOLES, ITS GREAT TO USE LESS CEMENT AND THOSE MATERIALS YOU BULK IT OUT WITH WOULD JUST BE LAYING IN HUGE PILES OTHERWISE, AND THE FINISH LOOKS AWESOME. CHECK OUT USING CLAY INSTEAD, IT ACHIEVES HUGE STRENGTHS, AND IVE READ OF CASES WHERE IT ACTUALLY IS STRONGER THAN CEMENT STABILISED RAMMED EARTH. IT WOULD BRING THE COSTS DOWN FOR CLIENT AND YOU GET MORE NATURAL COLOURS, ANYWAY, HOPE ITS STILL GOING WELL.

[st1dinoh]

@fieldofrob

why are you yelling?

[fieldofrob]

HI, EVEN THOUGH YOU USE A LOWER RATIO OF CEMENT TO AGREGATES THAN A POURED WALL WOULD, DUE TO THE FACT THAT YOU COMPACT THE MATERIAL AND EVEN BUILD A THICKER WALL, IS THERE ANY ADVANTAGE AS FAR AS REDUCING GREENHOUSE GASES? ALSO, YOU CAN SUBSTITUTE THAT CEMENT FOR CLAY, PERHAPS IN HIGHER RATIOS, BUT YOU IMEDIATELY GET RID OF THOSE GREENHOUSE GASES FROM THE CEMENT PRODUCTION THAT YOU ARE CONCERNED ABOUT. I UNDERSTAND CHANGING THE MATERIAL WOULD MEAN A CHANGE IN DESIGN AND OTHER CONSIDERATIONS....

"Two thousand square foot bungalow..." >_> I AM HURT!!!

[canalitofamily]

these walls are strong enough to withstand bumps, sections of the Chinese wall were built with this technique and still exist in our time

[frankt04]

Why won't anyone hit one of these walls to show there strength in any of these videos.

[frankt04]

Why won't anyone hit the wall with a hammer in any of these videos to show there strength.

These rammed earth walls have been engineered for both the Whistler snow load and the Vancouver sismic region. The walls have 2 curtains of 15mm re bar connected together through the insulation every 2 feet and secured together at the top of the wall.

[hit2fly]

it is an amazing technique for 3rd world countries and where wood is not easily available.

nothing is perfect, if a house is made of wooden frame then fire will eat it in seconds.

and when it comes to earth quake then even strong steel frame couldnt resist.

but earthen architecture is best for 3rd world countries, where other materials are not easily available and soil is a best insulator.

[johnny102marvin]

rammed earth homes do not do well in earthquakes.  The best home for eathquakes are wood framed homes.

[taiyoukaie]

lies

[johnny102marvin]

Look at the homes in earthquake Haiti. Many of them collapsed because they were made of various alternative techniques. Very few houses in Haiti were made of wood, because wood is scarce in Haiti.

[kingmike40]

Do the walls have to be covered with stucco or plaster? I have heard different opinions on the subject.

[tredeep]

Great vid, im seriously looking into this method for my own home in Az

[Khepramancer]

I love this method of building and think the work you guys are doing is fantastic. Thanks for posting these great videos.
