Fernando Pacheco of Brazil pioneered the use of lighter HDPE mesh tubing for simpler hyperadobe walls . Rebuilding after natural disasters and in low-income regions around the world has included earthbag . Although heavy earthen walls are usually dangerous in quakes , Nepal 's spring 2015 earthquakes left earthbag buildings in good condition near destroyed buildings . Engineer Nabil Taha developed the first general specifications for one type of exterior pinning reinforcement appropriate for the highest seismic risk zones . Several engineering students have tested uncured or low strength earthbag , and Build Simple has tested cured cohesive walls . Organizations building in Nepal are currently working with engineers to improve and refine reinforcement options for seismic-resistant earthbag
