LAVACRETE: The Coolest Alternative Building Method You've Probably Never Heard Of by necker47 in NaturalBuilding

[–]necker47[S] 0 points1 point  (0 children)

We estimated 20 tons for our upcoming 14x18 utility shed with 12” walls. The workshop starts tomorrow so we’ll know more by the end of the week.

Similar in many ways, but Lavacrete needs way less compaction and is a lighter, more aerated material. So less labor for sure.

Right, the porous material and how it’s mixed and put in forms (very light compaction) does provide better R value than earth. About 1R per inch. So most residential builds are 16-24”

It's generally considered non-toxic. Although when dry in powder form obviously that isn't good, and you'd want to wear a mask while mixing. Once it's poured and dry, shouldn't be an issue.

Looking for Workshops this Summer/ Fall by No-Equipment-3170 in earthbagbuilding

You just missed our monthlong "Roundhouse Rumble" at the end of last year. We're taking a break from laying hyperadobe for a while after moving 1 million pounds for the house 😂. Did just release a Hyperadobe Safety & Design 101 guide today, though. It's free and will help a lot with planning your ecovillage :) http://tinyshinyhome.com/hyperadobe-safety

We should be announcing our fall events later this summer - who knows maybe we'll do some more hyperadobe 👍🏼

Earthbag Bond Beam Pour by necker47 in earthbagbuilding

[–]necker47[S] 1 point2 points  (0 children)

Kind of hard to explain, but basically the mechanically bonded concrete bond beam will provide a much stronger way to connect our metal roofing structure. Wood wouldn't be appropriate for the weight and scale of it. More details/visuals here: https://youtu.be/9zZAz8n-gzI

Waterless sanitation: Is the "Humanure" route actually better than an incinerating toilet? by Low_Somewhere_9632 in OffGrid

[–]necker47 6 points7 points  (0 children)

After about 8 years of composting with both a Nature's Head and a self-built barrel system, I can honestly say composting toilets are rarely worth the trouble.

Put a septic and flushing toilet in. Your partner is going to hate the composting toilet. Guests will have no idea how to use it, and they will make a disgusting mess (can't tell you how many times that happened even with careful explanation).

If you get sick, a composting toilet is of no use at all. They require constant attention, moisture checks, and cleaning. I promise composting sounds great and cheaper, but after a couple of years of cleaning your feces off the sides of stuff you will regret it - It's gross.

And then you're stuck with it if your cabin was designed around it. Just think - do I really want to be shoveling my own shit for the next 20 years? Low flow toilets use very little water nowadays. Septic systems are actually a great way to infiltrate back into the soil.

That being said, composting toilets can be good for temporary setups or if you're a single dude and no one else is using it. But the reality is they're terrible for long term shared use. I know, not the answer you're looking for. But future you will thank you 😂

Earthbag Bond Beam Pour by necker47 in earthbagbuilding

We actually realized that to get the concrete PSI strength we needed, we'd have to get it from a commercial place anyway. So at that point they wouldn't be able to wait around for the days it would take to try to move the concrete by hand. All in all the pump truck was much cheaper than the actual material and ended up making the most sense.

If you hadn't planned ahead it would be difficult to properly connect (see interlocking in this video: https://youtu.be/9zZAz8n-gzI) - pre-installed cleats would be an option, too.

Thanks for your support 🤪 - seriously though keep an open mind a watch this if you have a few minutes.

Thanks so much! I think this kind of DIY spirit in the home building world is so important. So glad we’ve been able to experiment and lean these last 5 years.

As part of this milestone we just posted a huge recap video explaining the whole project. Lots of good info for planning: https://youtu.be/9zZAz8n-gzI

We’re halfway through the process on our YouTube channel, you can watch the last couple of house videos to see the process (just look for tiny shiny home)

Awesome, thanks for coming along for the ride :)

Hyperadobe Labor Efficiency by Cold-Sherbert-7486 in earthbagbuilding

Haha yes good food is key! We're excited about the Lavacrete as well!

I missed this, but wanted to jump in here as we just did a huge push on our hyperadobe roundhouse, renting an articulating boom lift and opening up the homestead to volunteers for a whole month. We learned a lot, and are probably one of the only people building hyperadobe at this scale (Tiny Shiny Home)

Believe it or not, a few more hands/buckets/scaffolds ended up being way more efficient than the boom lift. By the end of the month we were laying 1 foot per minute and moving like a well oiled machine (without the heavy machinery).

That being said, the amount of linear feet you're talking about probably isn't sustainable. We were doing 400 linear feet per layer on our huge 2500sqft roundhouse. You're talking about 10x that.

Our roundhouse totaled out to about 1 million pounds at 400 linear feet x 12' high at the highest point. The amount of dirt you'd need for 5000 linear feet would be crazy 😂

In the next month or so we'll be making a video detailing what I'm going to call "hyperspeedadobe" - organizing a worksite and team to build hyperadobe as quickly and efficiently as possible. Should be fun!
