Our previous post about Earthbag Locations caught the attention of readers, who are sending us information on additional countries. This is a good example of how it’s impossible to keep up with everything, especially when information is in foreign languages. Paula, one of our readers, said: “In Brazil there are various institutions that teach building techniques with earthbags and there are lots of places all over Brazil with these kind of buildings. This technique was developed by a Brazilian called Fernando Pacheco.”
Have a look in this video, they use a different type of bag:
Owen: I believe this building system has enormous potential. Here are a few facts from the website posted below. They are using tubes made of synthetic fabric — the same kind used in packing fruit. It seems the open weave in the fabric creates more friction between courses, thereby eliminating the need for barbed wire on certain designs. (This won’t work on domes, because you need the tensile strength provided by the barbed wire.) Also note, they claim enhanced bonding with plaster, probably because the fabric is not as slick as polypropylene. We’ll post more information about this exciting development as it becomes available.
Also note, the concrete foundation could be eliminated with 2-4 courses of gravel-filled poly bags or tubes with barbed wire between.
