I can either listen to the music or watch the process, I can't do both.

[@plasmamembrane3675]

Mute it my friend

[@seanhammer6296]

I've learned more in the comment section than from this video with it's annoying soundtrack.

[@voice-of-freedom]

Never use organic material in your stabilized earth - dig off the first foot and then use that after you test it to ensure the proper mixture. Cool music and nice personal experiment - but please never repeat in a real structure.

[@osamab814]

fassenkugel not really this way is used in South Yemen as well

[@Nabo00o]

@fassenkugel well you are partially right. What they do is mixing "fiber" into the clay/earth mix so that it is strengthened during drying, it might also help after solidification. Humus however is no longer strong organic fiber but broken down and mushy, perfect to grow plants in but bad for dry earth walls.

[@r.j.sigmund2424]

after about 1 minute of pounding with that sledge, i just headed out to buy concrete blocks.

[@andiarrohnds5163]

this is not the right way to make a wall. the soil is too wet and the mixture of sand and silt is incorrect

[@youssoufchalabi4627]

I confirm, beside the compaction technique was not correct !!

You have to use subsoil for long lasting rammed earth. The humus is spongy and wont compress or hold together.

[@remember25october]

What is the big idea wasting humus as such at all?!

[@davidsmith5023]

I didn't come for for a music video. I came for an informative tutorial with a dialogue that explains what the hell is going on.

[@jessicalatten718]

This was a good video. I've been casually doing research on this for years and this is the clearest, cleanest one yet. If you don't have other videos on how to make the rest of the house it would be great if you did.

[@Michael-it5zz]

You're supposed to let it cure before removing the formwork.

[@martijnheinsius7612]

You miss a step between 2 and 3... each rammed layer must be scratched/raked to roughen the top of it to provide a good mechanical key for the next layer. And as mentioned before, use subsoil.

[@architectcox6829]

nor do the wood blocks have perpend rebates to join to the next block - that step missed

[@RealisiticEdgeMod]

They did basically everything wrong but thats to be expected from varsity students. Its no wonder the chinese are building everything now.

[@FesterPussbucket]

Top soil would probably be a more stable feed stock if it was put through a settlement process first to float out organic material and then dried and sifted. I did some experimental projects a few years back and found that a cement binder is worth it in so many ways. Especially in a climate where moisture and frost heave could be an issue. I also experimented with a few additives to improve durability. It sounds a little nutty, but a little acrylic floor wax (future, Armstrong, ect.) Really helped the weathering resistance.

[@RebelofIreland]

Matt what would be your receipie for garden walls like this in Ireland? Just wondering I'm new to this.

[@MetalGearMk3]

If you use topsoil like in this video your walls will stink, smells like poop because of the organic matter. Always use subsoil for rammed earth.

[@NSResponder]

Jesus, the camerawork here is making me nauseous. -jcr

[@alexzabala2154]

nah, there are WAY better methods. this technique is way too labor intensive. these poor kids didn't even know how to properly use a shovel....but they get an A for trying something

[@whyjustyesterday]

What are some better methods?

[@davidchad77]

The SIREWALL method is probably the best

[@engisasp4808]

Please give me details about rammer process and how to select numbers of blows and rammer weight.

[@thomasgeorgecastleberry6918]

Don't you have to iclude water to activate the cement? Background music pretty pathetic.

[@SerenityGene]

"How to make a Mud Cake" Would be a better title to this video. Also a warning about the music would have been nice.

[@tbuttz]

I liked the video a lot more when I remembered KZbin has a mute button.

[@VerityNatural]

Yikes, never form like this please. This is how to NOT form a wall.

[@kennycouvillion8616]

the song is from the movie Holes

[@granthpal]

Well, the music indeed fits well with the hole-y performance of these jockeys. :(

[@johnperkins8895]

Looks like about 57 people beat me to the punch. Four-year-old video surely ya figured out the proper way by

[@bignail1954]

I like your vid but I especially like that song for the background. Is there a place I could buy the song and what is its name?

[@grey.the.ranger]

+Richard Vollnogle its from the movie Holes so you could probably get the song from iTunes and find it in the movies soundtrack

[@fig4159]

If everyone pirates everything, they'll stop making new. Aren't they entitled to be able to eat for their work? Making movies and music isn't free; why shouldn't you pay for it like the rest of the world?

[@evanherb5900]

@@fig4159 Literally nobody said they were going to pirate it. And artists rarely make a meaningful percentage of royalties anymore - their money is in physical merchandise. So it actually doesn't even matter anyway.

😄😃😄 This is interesting, I was taught in school that the great wall of china is built this way. Seriously! Thank You for sharing this😄 Best Wishes😄

[@salomepineda1238]

congratulations guys, well done and inspired us to do the same for our new little house in the countryside of Colombia.

[@BondedLiberty]

Holes. Good movie

[@hispanicuscorpus]

put you volume on mute, good video

[@ML6103]

Would someone mind telling me how you join one portion of the wall to the next using the existing formwork? I would imagine there is a some sort of hole for the rod between the two pieces of formwork that then needs to be filled? Cheers

[@hendrih.5349]

Hi, I know this is 2 years later, but what I've seen on KZbin and some other websites are that the block of formwork is removed witch would separate the first and second parts of the rammed earth walls. So instead of having all 4 sides of the formwork for the next part of the wall, you will be using the previous rammed earth part as a replacement for one of the sides for the formwork. For commercial house buildings I've seen the construction workers build almost the entire wall's formwork (except for height) and build the rammed earth walls like that. They also build the corners in formwork for the corner walls. You ca also make rammed earth bricks and build any way you like with those. I did not yet see what people use for mortar, but as far as I know, mud, concrete or lime could be used.

[@stephenroberts8361]

how do you make a long wall and the start next upper course how do you go round corners they never tell you how

[@amankhan4527]

good

[@alquilerestemporarios2700]

wooow alto tema! buenisimo

[@trollbbqer1267]

Great vid! I want to build an earthbag home using similar stabilization process. TY for sharing, a $5,000 new home by this type of construction is attainable for mid-income families, is weather resistant (with proper stabilization), and lasts for years!💗

[@beretgascon]

Love this - thank you! More fun than making 300 CEBs !!

[@remember25october]

Basically you need complicated tools to properly ram the earth. And it is not even the earth, but some well prepared mixture with addition of cement. I suppose I need a robot to do this for me.

[@kadiyalabharath5185]

Anyone tell me what is that song name (background music)

[@GardeningWithDoug]

Good work you guys.. I want to make garden walls out of this stuff. Thank you for showing us how it is done.

What is the process for stabilizing clay?

nice video, nice people, nice work.

[@youzhou2946]

so is the soil need to be dampened?

[@samanthanicholson9015]

what type of earth did you use with the cement?

[@skobiekilla]

Did it work? Any follow ups.

why cement its not needed

[@rawmark]

You do know that there is no need for cement if the amount of silt is high enough, right? This is the big problem I have with Rammed Earth construction in North America. Most builders aren't aware of this fact.

[@bendover9862]

You will need it if you want to resist weather erosion.

[@theturkanabus3610]

you do NOT need cement at all. the reason the 'unstabilized' earth in the video can get holes is because it is too wet. also, their compression technique is too soft

[@williamjackson5942]

The houses built in the middle ages of rammed earth are still around because the roof keeps them safe and as you say they were built using just slightly damp earth rammed hard and allowed to season layer by layer. No cement was used or really needed but it certainly would not hurt to add.
