Touring earthbag building projects in Nepal has allowed us to gather hundreds of photos, dozens of hours of video footage, and discover lots of interesting new earthbag techniques and developments. I now have fresh content for lots of future blog posts. The volunteers and workers here are very good and so there’s quite a bit of innovation taking place. The photo above is one example of how earthbag builders in Nepal are improving the building process by sewing perfect corners on earthbags.
We’ve nearly finished an earthbag water tank with narrow tubes that cost $200 in materials. Plastic tanks this size retail for around $1,350 in Vanuatu, so this design costs far less than the main competing product. It won’t blow away in a hurricane, break down from UV rays or taint the water with plastic chemicals. Our water tank includes a domed ferrocement top that’s exceptionally strong. It can be built in 2-3 days by four workers with minimal skill, although plastering skill is very helpful. There’s a huge water shortage on the islands here in Vanuatu, as well as many other places. Those who learn this method could make a lot of money selling water tanks since demand is high and cost of labor is cheap.
