Larger structures such as schools and other commercial structures in earthquake zones require strong reinforcing. Patti Stouter and I have been working on a school design for Haiti. The first earthbag school is now under construction near Leogane. Part of the design is this reinforced earthbag buttress, which will help stabilize the long walls.
Complete drawings are now available for free on our EarthbagStructures.com website, along with many other resources on rebuilding with earthbags in disaster areas.
