Hyperadobe is too expensive? The material is, as far as I can see, admittedly somewhat more expensive than woven bags, but on the other hand you don't need the barbed wire, which is a slight savings.
That would depend on where you live, The omission of barbed wire in a seismicly active or potentially active zone could prove to be a fatal mistake. A dome still requires the use of barbed wire regardless of where you live, or what kind of bags you use.
The following company offers misprint bags at $150/1000 (15 cents each)

Even in a vertical walled structure, if you want to use barbed wire between the wall courses, it is dead cheap - a quarter mile roll of 12.5ga 4 point is well under $100. We fully intend to use it in some places, such as wal intersections and around openings (which will be arched).
How would you reinforce besides with barbed wire?
Chicken wire? Buttresses? Recycled fish nets? Rebar?
We are looking at building with earth in Japan, the mother of all seismic zones, so it is a big concern.
Thanks for the response, Doug. I am familiar with that blog. I had read a little about Prof. Inoue. The organization he works with is considered a cult by many in Japan. I do take that label with a grain of salt, because the Japanese tend to label anything outside the mainstream as a cult...and not entirely without reason as there are lots of cults in Japan. Regardless, I hope to see Prof. Inoue's domes one of these days.
this is a big tube instead of lots of bags. It works exactly the same though, you just have two ends to seal.
Its WAY cheaper....
That's solid polyethylene tubing, not woven polypropylene. I doubt the earth mix inside would cure with any speed as the moisture would be trapped inside, and I also wonder how well it would stand up to tamping and/or barbed wire in between the courses, especially as it's only 1.5mil, which is REALLY thin stuff.

Hyperadobe is too costly for our limited budget unfortunately.
I saw the bags on calearth.org - nice bags but wow are they pricey.
My thinking is that if I make 100 earthbags for 30 days, I'll have 3000 earth bags.
in 90 days.
If I can make one earth bag in five minutes, then in one hour, I'll have twelve earthbags. So if I have another set of hands helping, we can have our 100 earthbags together in about 5 hours in one day, not counting breaks, etc.
Not everyone is comfy with a small house or a dome/round house.
When you consider the benefit of not having a mortgage (low end $800/mth)
the five hours a day don't seem so bad for 30 days.
Someone posted that 1000 earthbags makes 700 sq feet of wall space, so
3 times that would be 2100 sq feet of wall space = 4 exterior 40 x 8 walls (1280 sq. feet of wall space) (about the length of a shipping container plus some walls for inside) = 1600 sq. foot house.
Reasonably speaking, this could be completed with about $5000?
The exterior could be secured with ferrocement and remesh, cured well for the maximum 21 days-28 days? So the house could be completed in six months.
Is it possible for a poverty line family to have affordable housing that they can live quite comfortably in. Can I do that? Numbers seem to show that it is possible.
We can offer Tube Netting Rolls from our stock, or if you require a different size, fabric, colour etc. than we hold in stock then we can have
it made to order to your specific eco friendly bag supply requirements.
Our Tube Netting Rolls are ideal for a building product, packing of vegetables, or anything that is on a continuous flow and needs to be contained".

You can find all calculations for the rest of the process from How many 50lb bags per ton, cost of bags, the barbed wire then calculate cost of materials per square foot, total number of bags by number of finished bags per hour and finally cost of labor.
You will also find number of hours to build the wall as an example the given in the book which uses 6 people in three teams you can lay 24 bags an hour or 192 in 8 hours so you could lay all 1,320 bags in 7 days.

Hoping that someone knows of an organization that donates free earthbags or at least a price cheaper than $250/1000.
The earthbag house I'm planning to build will need 2000 earthbags min, closer to 5000. I have 3 kids - I'm 5'10, hubby 6'2 so we need it to be tall - kids will prob. grow to be taller than us. Filling that many earthbags is hard, but easier than forming and baking that many adobe bricks with nearly the same bennies as adobe brick.
I found this place that sells used but clean sandbags but have yet to get the quote back from 'em. After reading the awesome posts on here, I'm sold on earthbags completely. The results are amazing!
