Prefabricated Earthen Walls — 8 Comments

  1. Thumbs down on this one – greenwash. I agree with all you say about it, plus one more thing – there will be a massive hole in the ground near the manufacturing plant where all that soil is coming from.

  2. Clifton Schooley sent me this observation:
    I don’t see a future in prefab RE walls, I have made some huge ones ( 18′ tall) and also consulted with a experienced RE builder who shared the challenges of this idea from experience. The real solution is to improve cast on site RE walls, there is a lot that can be done to improve efficiency and lower cost.

  3. I think it s a good step compared to prefabricated concrete wall that i see sometimes here in France.
    No sand quarry, easily cyclable, easily maintainable.

  4. I completely agree that shipping pre-fab earthen walls does not make sense — it almost sounds like a parody of eco-building. The beauty of earthen building is that the dirt is right there!

    At this moment (yesterday & today) we are digging a big ditch for a partially submerged greenhouse. One of the great side benefits is that we now have 130 cubic yards of dirt, for our spring house build! We will be using earthen plaster inside and out, and earthen floors. Our dirt is very sandy, but this dig hit a sizable clay layer– couldn’t be happier!

  5. Perhaps the company could make the manufacturing process mobile and make the walls on site. I think everyone would profit from that approach. I would not like to pay for shipping a rammed earth house anywhere.

  6. I totally agree with you. The embodied energy required for transport and assembly would be very high compared to building on site. And with the soil not stabilized I would think cracking could be an issue in transport and set-up. And thank you, thank you, thank you for pointing out that high thermal mass BY ITSELF is a poor choice for most climates! I’ve seen so much misinformation on this point and people just starting out don’t realize the difference between thermal mass and insulation, at least not in relation to different climates, and when it’s okay to use alone.

  7. How do you install electrical and plumbing doors and windows looks like more work than there worth and what’s the cost not practical for remote areas
