Earthbag building techniques were also explored in Sri Lanka after the 2004 tsunami . Multiple earthbag construction projects have been completed in Haiti , most of these after the earthquake . First Steps Himalaya and other charities had built more than 50 earthbag buildings in Nepal prior to the April 2015 earthquake . Since then , local builders flocked to ongoing earthbag training opportunities , including those by Good Earth Nepal , which have led to official Nepal building code acceptance of this technique for residences . International NPOs have built hundreds of contained earth or earthbag buildings in Nepal as well , more residences than larger clinics or schools . NPOs are asking for more structural information to be better able to choose reinforcement types and intensity appropriate to local soil strength and seismic risk . University testing has begun but more is needed
