Brother could you possibly at some point go over how repairs would be made later on? or hanging pictures, adding outlets, any of that are some of my main curiousities at this point still

[@kovser]

Hanging pictures is ok, but if you are installing cabinets or a plasma TV screen in the kitchen you need to assemble it onto a stud. Adding outlets is ok, you just have to use lime based mortar with existing hemp hurds that you have taken out of the wall in order to patch the holes.

[@alextownsend6662]

Maybe a combo of building techniques and materials would be desirable. I could see using hempcrete for exterior walls, but building interior walls with standard studs and drywall.

[@hempireua]

@@alextownsend6662 drywall is considered a material of high toxicity in EU. Just some food for thought what you have been putting in your houses for decades.

[@davidfajfar229]

[@hempireua]

outside vapour permeable stucco- check with local suppliers. Internal: clay plaster, lime plaster, wood panels, something natural is A MUST!

[@SelfMakeover]

I'm obsessed with hempcrete. Maybe you could make block forms and them make hempcrete blocks (they look like legos). I saw another video with them and they are so fabulous!

[@kovser]

Blocks is a different type of product. IT works great if its a load-bearing block.

[@cathyhirzel8934]

I would love to see this in Georgia, where I live. I am currently building a barndominium home and I would have loved to do this kind of build but I imagine it would have been difficult to get building permits for this type of build. Finding contractors to build with this material would have been another issue. For my next build I would like to try Hemp.

[@kovser]

Its only a question of effort. Georgia europe or Georgia, USA? YOu should use hemp, its your health you are talking about.

[@jacquesmertens3369]

If you have a lot of spare time, or if you live in a country where labour is cheap, this process can work. But there's also the matter of building regulations, insurance etc. (edit: I initially described OSB as a toxic fire hazard, which it is, but OSB is used and re-used to shape the hempcrete, not as building material) If you can get pre-formed hempcrete blocks certified they would be an excellent building material for bungalows. Pre-formed, light weight hemp blocks (hemp, not hempcrete) are also very useful to insulate existing homes from the inside, when insulating from the outside is not an option (e.g. historic buildings).

[@hempireua]

Thank you for your comment🙏 We don’t use OSB on any of our builds. It’s a very toxic material.

[@genocanabicea5779]

Building a frame wall and covering it with hemp mesh and then packing the wall with hempcrete makes a very strong wall. The frame wall form can then be removed and reused to make more walls.

[@kovser]

it depends on the mix and the binder. "Very strong wall" is a very broad example. Can this wall hold two stories and a big hipped roof? our mix is very light - 260 kg/m3 in order to create maximum energy efficiency.

[@sz4179]

Hempcrete looks to be fantastic infill, with a ferrocement but permeable type of outer shell. Imo roof/ walls still need the vertical load bearing support of wood framing.

[@aleksandrbangers8756]

[@BrandonAbel01]

Muchly appreciated overview and looks like a fantastically healthy house. Key point, it's all about finding your local supply of materials. But what ingredient is in the binder that lets the form come off right away?

[@heartobefelt]

@@hempireua so you are not using pure lime as the binder ? In Australia at the moment only one company claims to have building code approval with their hempcrete lime and their price is ~ high. thanks for posting . good logic in your building method although i wish i could do lower labour input with shotcrete method to move material from the ribbon mixer to the wall void.

The timber can be made from hemp as well. Hemp crete made from a material with a finer grind makes it denser. And using a hemp mesh the wall can be reenforced.

In this house, is there a method for dealing with internal humidity moving into the ceiling? Is there a ventilation gap between the top of the hempcrete and the OSB? Again, thank you for the sharing your knowledge.

[@davidfajfar229]

Osb itself acts as a humidity barier, no problem with little humidity geting into osb because it easilly evaporates into hempcrete any day. Most important layer is the one after hempcrete😉

[@douglaspaulsmith]

Love this project and your clear descriptions. One question I have, is the lime render...if you coate the building in lime, would the wood structure - studs and beams - not shrink and expand with the humidity, thus cracking the lime render on top of it? Over time, I wonder if this would be a problem. Many thanks for sharing this and your expertise...

[@hempireua]

You need to install a mesh , otherwise it’s going to crack. Sometimes even two layers. First mesh goes right on the scratch coat and then the second goes right before the final coat of plaster.

[@irishcoffee6894]

Thank you Sergiy, for explaining. Perhaps a narration in concern of the sound would be great, the noise was now and then too much (for me, I'm hearing impaired) Everywhere I hear you only MUST use the shive (inner core of the hemp) for hempcrete, but the handful of hemp you picked up contained also fibres with leaves...... Can you please tell me if it is mandatory to ONLY USE the shiv(e) ?? What kind of binder do you use ? "Normal" cement (?) Do you use also a part lime in the mixture ?? Would love to hear the "exact" used materials. I'm planning on making our own hempcrete house in about 1 or 2 years, that is why

[@hempireua]

Thank you for your feedback, it was a bit too loud. That will be removed in future videos. Hemp hurds can contain fibers up to 10%, no more. So a bit of fiber is ok. We use hydrated lime in our binder. The exact proportion by weight: 1 part water, 1.5 parts hydrated lime binder , 2 parts water

[@scentybeast9531]

Fantastic video. Whats the approx R value when this is complete? You don't need any other insulation or vapour barrier besides this and the lime plaster? Any issues using this with a lightweight steel frame eg rust, etc? Thank you, slava Ukraine - SB

[@hempireua]

2.5 per inch on paper, but in reality it’s much more energy efficient since the middle of the mix is not being compressed as much as the edges of the wall.

[@bodymovin73]

great video, thank you! but what do you use between your timber frame and the concrete slab?

[@kovser]

[@kfffisher]

Thank you for this video. I have plans to build a few hempcrete cabins for rental income. Originally I had planned to use strawbale construction which I have used extensively for a few construction projects, and was very happy with the outcome. But hempcrete just seems like an easier method with the same outcome of being natural and of high insulation factor. I'll participate in a hempcrete workshop prior to construction but I was curious how you compact the very top layer of hempcrete of a framed wall where the roof rafters and sheathing would be in the way to allow for compaction. For example: At 12:14 in your video, how was the top layer compacted for the window framing with the bottom window timber not allowing you to compact the hempcrete from above?? Curious and stumped!!?? Thanks!

[@hempireua]

You install a formwork from one side of the mix and you compact hempcrete from the side, not from the top. Or other option, the bottom plate of the window frame install after you apply and compact hempcrete. Good luck with your project! 🙏

Thank you for kind words. Thermal conductivity for hempcrete is 0.07 Which is pretty high for biobased materials. We can make our thickness 10 -12-14-16 inches. Hempcrete is never limited by the thickness of the timber frame. Thats the beauty of this tech!

Just curious, could wheat straw couldn't be used when hemp isn't available? Anyone know? I mean I know it's not as hip as having a ganja house but wheat straw is EXTREMELY abundant as it is a byproduct of producing wheat.

[@hempireua]

You could use straw. But hemp is different in terms of thermal performance and humidity regulation.

Доброго дня! Штукатурка на основі гідравлічного вапна найкраще рішення. Товщина утеплювача може бути різна.

Do you have any problems with cracking where the timber meets the hempcrete?

[@hempireua]

Hempcrete has to flush with a timber, or if covering (going around) the stud the thickness of hempcrete should be minimum 3 inches (7.5 cm).

[@sunroo]

I mean cracking of the lime based render on the outside, I realise you should use mesh in the render to minimise cracking its just with this 2 stud wall system your creating a lot of timber to hempcrete joins which may be more prone to cracking of the render, do these joins hold up well over time? Especially if you use mesh

[@hempireua]

@@sunroo this house has timber shingles, so this double stud system is the correct one. For the exterior render it’s better to sink the stud in the hempcrete. You are correct.

I am in the U.S. and I cannot seem to find any in person trainings offered for 2022. Are you aware of anyone offering hands on experiences installing and finishing hempcrete. Also, I would suggest that anyone mixing hempcrete wear a high filtration mask as exposure to this dust might be the most hazardous part of working with hempcrete.

You can insulate it from inside

@@hempireua you mean I should build a concrete house with balcony and then insulate it with hempcrete?

[@hempireua]

@@wiezyczkowata I need to understand what you are trying to do. It’s not a load bearing material. It’s quite clear that you need timber frame or some kind of surface to attach it to.

@@hempireua sorry to answer so late, I had a hectic couple of days, what I would want is a 2 story house made of hempcrete with balconies on a second story, if I build a hempcrete house but with a regular ceiling like in a concrete house would it be able to support balconies? or does a hempcrete house have to have a hempcrete ceiling?

What is the stud spacing on this house and how do you determine where to apply the diagonal bracing? Also, is that a double stud wall with offset studs or are you using Larson trusses? We are praying that the Russians haven't destroyed your beautiful homes and pressing our government to support Ukraine to defend itself against the horrors of Putin's illegal invasion of your sovereign nation.
