What about using tires for foundations? In my opinion, earthbags are superior for foundations and walls. If you’re not convinced of this, tamp one tire (the way it’s supposed to be done, which takes 20 minutes or so). Then tamp the equivalent (in cubic inches) in earthbags and see for yourself which is easier. But it gets better, because lower courses can be filled with gravel (double bagged for durability). I could fill and stack about one-half to one whole course of earthbags on a small dome in the time it takes to tamp one tire. That’s a 10 to 20-fold improvement in speed! Swinging a sledge hammer is gut busting hard work. Tamping earthbags isn’t exactly “easy” but it’s way easier and faster than doing rammed earth tires. And with earthbags you can use insulated fill material such as scoria or perlite to create an insulated foundation.
I love the look of earthships and admire all the wonderful eco features, but I’ve learned how the same things (roofwater collection, solar hot water, etc.) can be integrated into a well designed earthbag home. With earthbags you can have these same features at a fraction of the labor and time.
Thank you for pointing that out, I agree time and energy saved by using earthbags over tire is very significant, and as natural buiding is mainly work labour, it therefore reduces buiding “costs”. However, do Tires and earthbag have the same mechanical caracteristics, and aren’t there any advantage of using tires over earthbags in a foundation?
I can’t think of anything good to say about building with tires. I’ve seen abandoned earthships firsthand, and have heard how people watched their dream of home ownership slip away due to the years of hard labor required. They’re definitely not “free” when you factor in all the labor. Very few people are cut out (physically able) to build tire houses. They’re sort of a trap if you think about it, luring the unsuspecting. And what about the tire dumps left behind after people give up? They become a public nuisance. Another complaint I have is how some books tend to treat all natural building methods more or less equal. They’re clearly not. Why use tires when earthbags can serve as foundations, retaining walls, work in wet environments like greenhouses, hold back floods, withstand hurricanes, excel in hot and cold climates, and on and on.
hello, curious about the basic principles of creating a dome style home,in canada…..alberta.bound location where.temps.can get to-30c.
Does it make more sense to have thedome home down below frost line (here it is 3ft) and can you direct me to plans for a small style home with maybe a loft design for a 1-2person style………with the possibility of a cob oven and a rocket stove design incorportated in it or is this better suited with a real wood stove .
Books, web sites, blogs or any direction of all that would be offered would be greatly appreciated .
thanks for your time
Regards,
Be sure to check out my Earthbag House Plans website that includes three dome plans that meet your description: http://earthbagplans.wordpress.com/
The Peace Dome is small and simple to build, and has a loft: http://earthbagplans.wordpress.com/2009/04/19/earthbag-peace-dome/
The Enviro Dome is larger and more comfortable: http://earthbagplans.wordpress.com/2009/02/22/enviro-earthbag-dome/
The Earthbag Roundhouse/Dome Cluster is quite luxurious: http://earthbagplans.wordpress.com/2009/05/12/earthbag-roundhousedome-cluster/
Check out my article on building with earthbags in cold climates: http://www.earthbagbuilding.com/articles/insulated.htm
Building below grade can improve thermal efficiency to a point, but I don’t recommend this for areas prone to water damage. For cold climates, I would focus on using lightweight insulation materials (lava rock, perlite, etc.) and building small.
Rocket stoves are great! It makes sense to include a whole range of appropriate technologies in your home for roofwater collection, solar, composting toilets, etc.
