Because no earthbag buildings were seriously damaged by seismic motion up to 0.8 g in Nepal 's 2015 quakes , Nepal 's building code recognizes earthbag , although the code does not discuss soil strengths or improved reinforcement . Nepal requires buildings to resist 1.5 g risk although hazard maps show higher values . Better trainers assume the use of cohesive soil and barbed wire , and recommend vertical rebar , buttresses , and bond beams , but rule of thumb earthbag techniques should be differentiated from contained earth that follows more complete guidelines
