Thanks for watching! And to clarify a point I make a few times about the curing of the hempcrete over time I need to clear up that the process of the hempcrete sucking carbon into the walls is called carbonisation - not petrification or petrifying.
Thanks! Create the form you want with molding first. 1/4 cut PVC pipes can work well. If going off form hempceret that one must be diligent with the packing and tamping but if it's rendered then you can refine the cures with render layers...
This is actually insanely good. Not only does it last way longer than concrete, but it's also a renewable resource and good for the environment though at the rate we're f****** up the environment. I don't know if little things like this is going to help
Thanks solarwind for your comment! But we gotta try hey!? And from small things big things come. I made these videos late 2022. Now I’m building a Hemp Building Directory www.hempbuilding.au with a famous Building Designer and within 2 weeks we have designers and architects, builders and installers, engineers and consultants all signed up. This should be good for the nascent hemp industry. Next we are involved with Professors at Syd Uni ag institute. The ball is rolling and thanks for giving it a push with your comment!
We need to be building with bamboo, hemp, and wood to remove as much carbon as possible from our atmosphere. These building materials should be made compulsory in earthquake zones like Turkiye.
I'm of a thinking "better to do anything then nothing at all", if we don't do anything then nothing will change and it can get even worse, at least we try
Hi guys this all sounds good but what about fixing out, doors skirtings, jams, architraves, cupboards etc, how do you secure these to the walls without it all falling off, also do you need to have the roof on when packing out the walls with hempcrete? And what about the external walls, can one use stone blocks or bricks as an external finish?
- That is quite a few question....thanks! I'd be happy to arrange a zoom or similar meeting so we can have a chat and I can address some of these.

Hi, great work! The hemp is really amazing. Maybe I got this wrong but I heard sand shouldn't be used in this mix or maybe it is when you only use hemp + lime as a plaster rather than building a wall? Thanks a mill.
Hi Julien, thanks for the comment and glad you like the videos. I've seen issues with sand mixed in walls and other walls that perform better due to the extra thermal mass. But I think 'no sand. is now best practice...
Well detailed, I have few silly questions. I need to retrofit a wooden/timber wall, please guide about the construction technique/detailsrequired to place hempcrete as insulating material between this wooden/timber facade and internal wall.
Hi Akash, thanks for commenting. That's more of a bigger question. If you want 15mins free consultation reach out to me on jeremy@environmentarian.au and we can go from there....
@@JeremyThomas_Environmentarian I don’t personally but a good conversation to have. Might do some research on them. So good seeing a building product tick all the boxes
Beautiful wall. Fine work. Aside from aesthetics, does the hemp wall provide a function as an internal wall? Will this wall serve as a thermal mass? Wonderful work here.
Hi Sean, yes, hempcrete has both insulation and thermal mass properties. So the thermal envelope of the room, the house, will be managed passively thanks to the hempcrete. Sound conditioning in the room is also amazing with no reverb/echo.
Well commenting here a a start. The hemp community is very friendly. There are workshops that would be good to attend so you can get hands on with hempcrete and meet other people in a welcoming environment. Check out www.hempbuilding.au and reach out to the businesses in your area. Enjoy!
Any design is possible. I’m standing on the balcony in the first shot. Adam Abbott is standing on the balcony for his interview. Balcony’s are an integral design feature of Queenslanders as they regulate the heat especially during summer.
Sorry I don't have the exact amount but it was about 3 pallets - you can see them stacked in the video. The river sand adds thermal mass but isn't used in all hempcrete mix recipes.
@@JeremyThomas_Environmentarian Excellent, with those details, I can make an approximation of how much I need when comparing the square footage of my future structure with the one in the video. Thanks!!
It is also not available around here, (or if it is I am unable to find it) and to get it would be more expensive then just using standard building materials.
@@erikzorger3311 for now the initial cost of hempcrete building can seem expensive. But when you factor in thermally controlling the spaces over the 100 plus years of the building and the fact the much less energy is needed to heat or cool these spaces then there is a factor that could help balance out the expense over the longterm.
@@erikzorger3311 In Australia for many years we had a hurd supply issue. We were importing from France and other countries. For many the import cost was worth the value of the product considering they were building a legacy for the future...

Hemp retrofits are the remodel of the future! Heck yeah. Nice work fellas
Thanks buddy!
Thanks for the video mate. Very interesting material and process.
@@dartology no worries. Thanks for the positive comment!
6:30 min. The cement is only to get it harder. The sticking is done with the lime.
Great video, and interesting to see bigger forms being used. How do you do our curves? With moulding or once the form is removed? Thanks

Love this - can you hang up photos frames etc on the hemp walls or how do you do that?
Hi there, great question! You have to locate internal studs. Or use this method.

Hello, I live in Qld and would like to see some hemp houses up close, meet with residents and builders. Daunting as i am a hermit 😂😂 How do i start?

can you have a house with balcony if you are building with hempcrete?

@@JeremyThomas_Environmentarian that's so good to know, thank you for the answer!!
Ok experiment with a concrete additive. Do the bugs like it and dies it decompose over time.
Approximately, how many pounds of hempcrete was utilized in this home? Also, how does the river sand contribute?
Sorry I don't have the exact amount but it was about 3 pallets - you can see them stacked in the video. The river sand adds thermal mass but isn't used in all hempcrete mix recipes.
@@JeremyThomas_Environmentarian Excellent, with those details, I can make an approximation of how much I need when comparing the square footage of my future structure with the one in the video. Thanks!!
if hemp was available in my area I would love to do this. I'll probably end up using sawdust in stead.
saw dust can work but hemp has a high silica content which means it sticks together better then other organic materials
It is also not available around here, (or if it is I am unable to find it) and to get it would be more expensive then just using standard building materials.

Do you have any estimate on how much the walls would weigh?
I'm wondering if it would be too heavy to retrofit a manufactured home with?
It's a very light weight material. But that's the kind of question to run by a structural engineer, preferably one that has experience with hempcrete.
So do you also do all the interior walls with hempcrete as well or just the exterior?
Where did you buy the hemp hurds?
I am not sure where it was sourced from however there are plenty of suppliers listed on the website I run hempbuilding.au/suppliers/
Surprised to see the hemp wrapped in plastic 😢
Surprised why?
It's "Tig" from Sons of Anarchy.😁
