Inside Austria’s Rammed Earth Factory: No Cement, Just Earth - Revolutionizing Sustainable Building

Let's bring you all down to earth again: Explore sustainable building materials on a groundbreaking scale in this episode of Reconstructing the World! We continue our journey in Austria at Lehm Ton Erde, where Professor Martin Rausch showcases the powerful potential of rammed earth construction. Using only natural materials like clay, gravel, and local stones-without any cement or concrete-Martin's team creates earth-based building elements with minimal CO2 emissions and unmatched thermal mass.
Tour their massive facility and discover the incredible processes involved in creating durable, eco-friendly walls. Learn how this modernized ancient technique, from adaptive formwork molds to the “Roberta” ramming machine, makes rammed earth construction feasible for large-scale projects. Not only do these walls have impressive structural integrity, but they also regulate indoor climates, reduce condensation, and create healthier indoor air quality.
From hybrid timber-and-earth constructions to energy-efficient office buildings, see how rammed earth is transforming sustainable architecture. Could this be the ultimate solution for a greener future in construction?
Watch to find out why rammed earth could become the top choice for sustainable and resilient buildings! To find out more about the amazing work at Lehm Ton Erde, visit www.lehmtonerd... (Not sponsored!)

interesting content. However I think the channel would benefit from having the guy with the cap, stay out of frame and keep quiet throughout

[@NathanNostaw]

Yeah, every word from him was limiting the genuine info and explanation.

I respect your opinion, but I also believe these videos are primarily made to be an approachable introduction for a wider audience to sustainable building practices. Its sounds like you're genuinly interested in the topics of this channel, so you're probably doing more detailed and deeper research anyway. There are already monotonous deep-dives into all of these topics on the internet, but no one knows about them because it is boring unless it is presented like this channel (for the tiktok generation in particular haha).

@@manuprosser8778thank you! This is exactly what we went for - incl the good Anders with the cap who was part of this from the beginning 😊

Thanks for dropping the video! Longest 2 weeks of my life.

Thank you for being patient with us! We hope to get the possibility to make more frequent videos, once we get the viewers for it, but thank you for being here from the beginning 🙏

@@ReconstructingTheWorld I have a new, interesting sloped roof technology that has already been built on existing buildings. I can't get your email address on this channel, it doesn't work. If you wish to learn about that world unique solution, give me some email for contact.

Brilliant material - superb video!

nice tech; but the yuk, yuk vanity style channel is a fail

[@ReconstructingTheWorld]

Hi! What is a vanity style channel? We'd love to learn!

[@someguydino6770]

@@ReconstructingTheWorld The type of channel where the "host's face" and their "reactions" are MORE important than the content. Basically it's all about their ego and thier lame attempts pretending to be an actor.

@ReconstructionTheWorld At 16:24 you write "We know, we have a whole channel about it!", while exclaiming "I hope every house in the world will be built like this". While I do appreciate that you finally have learned this, I do (once again) encourage you to preferably delete your episode 1, or as a minimum write a fat disclaimer "We were dumb and didn't mean to praise using 20 times as much lumber (from clearcuts) as necessary"

[@MM-sf3rl]

They need to automate the rammer.

[@mooselee902]

already one, there are small scale machines that can construct the entire wall

[@facundoarboit1020]

Is the recipe for this particular rammed earth a trade secret or is it something you can share with us? Pleease… 🙏

[@zurezkhan]

I figure it’s all in the name

[@ReconstructingTheWorld]

Professor Martin Rauch has not shared his recipe with us, but if you saw our previous episode, he tell us that he has one with casein in it... Calls it cheese 🤓 If he one day makes a recipe book, we'll be the first to buy it!

Well clay / soil is a very interesting building material, but it is also not renewable material / growing material. Or at least it takes very long time for the nature to produce it, I guess. When you dig it up, it doesn't renew itself - but in the end you can put it back, so to speak. But what I want to say is that you cannot allways use the soil, directly from your building site. Either the material is not good enough (does not have any or not enough clay) or there is not enough soil for the whole building. So if you want to build all buildings in the World this way, you end up digging big holes, just as the excavation for gravel for concrete. So it is interesting, but not in really large scale.

Could hemp fiber replace some of the wood chips? 🗯️⏰🙌
