Building with Hemp – An Incredible Natural Insulation & Sustainable Material



Anthony from du Chanvre has built over 45 houses using hempcrete as a natural and sustainable insulation material. Hempcrete is made with a mix of hemp hurd (fibre), hydraulic lime (binder), and water.

You can follow Anthony’s building projects and get in touch with him on Instagram, or on his website here:

Hempcrete is not load-bearing, but it does provide insulation, thermal mass, and it regulates temperature and humidity. The R-value of hempcrete is R-2.1 per inch.

Some other advantages of hempcrete is that it resists fire, mould, and vermin, and it eliminates the need for a vapour barrier and drywall (gypsum). Instead, you protect the hempcrete with natural lime plasters on the inside and on the outside of the building.

Using hemp is a sustainable building material because it is carbon negative (it stocks more carbon in the fibre of the plant than is used to grow, harvest, and process it).

We’re very excited to learn about new and innovative ways to use natural building materials in conventional construction projects.

Anthony says the cast-in-place construction method creates the highest quality of hempcrete, but pre-formed, pre-dried hempcrete blocks are more likely to allow hempcrete to go mainstream.

In case you missed it, Anthony references a Bob Marley song at the end of the interview, comparing the conventional construction industry to the big tree, and the natural building industry to the small ax that will cut it down:

  1. I have read that hempcrete is weaker than concrete, but hemp is stronger than steel. Can someone please explain why this is the case.

  2. looks labor intensive and costly. if there is a water pipe burst it would expand the hemp wall and rot. I like the idea but needs more work.

  3. So the decline of hemp being grown is part of the global warming problem the democrats complaining about wasn't it democrats in office during the decline of hemp but in California democrats started using hemp to get votes during the 2016 election CNN had special segment on Marijuana witch had spin offs on other cable channels

  4. I'm gonna tinker with hempcrete in my back yard.

    Need to finish up a paver stone project, and right now a 10 lbs bag of hemp is around 40 dollar, and hydrologic lime is 6 buck a 5 lbs bag.

    I'm really curious to see how these stones turn out.

  5. Hemp is the sole reason for the demonization of cannabis. I wonder why the elites who have so much stakes in all these different industries haven't just monopolized the weed and hemp industry. Greedy fuckers

  6. The carbon concept is a myth pushed by the Oligarchy for control of the masses. Stop believing in Oligarchy pushed ideas. This is apart of the 2030 lockstep agenda. Poisons and pollution other than carbon should be the focus. That will lead you back to the Oligarchy owned corporations who are the real culprits of the degradation of mother earth.

  7. stated insulation value varies between 2.1 and 3.9 per inch depending on who you talk to. Wonder which is closer to the truth.

  8. If anyone knows the true story of Nikola Tesla then you would understand it has nothing to do with the advancement of humanity. Its all about money and greed and keeping the alogarch families in power.

    Of course we could stop and drop everything right now and grow so much hemp. A plant that can build and create almost anything in our daily lives. But it will not happen if we keep ignoring history and the strong holds the devil and his people have on the nations.

  9. Lumber lobbyists are the ones preventing widespread use of this material. People in their respective countries need to tear these greedy lobbyists down from their ivory towers and leave them in the mud where they belong.

  10. Love everything about this. While the finished product is indeed not only safe but healthful, you should protect your skin and lungs from the caustic lime while working with it. Lime is quite alkaline and can cause tissue burns.

  11. How are you using the hemp….as the exterior facing? I read that it's not useable as a foundation wall but only for interior walls…but it seems you are using it here as exterior walls. do you have more info. on the specifics of using it?

  12. This is a very old technology, and if you will go to Europe you will find many homes that were build in this manner. They just used straw instead of hemp that's all

  13. "Two masons can build a house in two weeks using the hempcrete blocks." This is for me! Hoping we can build with hempcrete and grow the hemp in Guatemala. Not legal yet I don't think… anyone know? Jan 2021.
