Maximize strength and ductility 

Enough strength

without too much steel 

Earthen walls are reliable even when strengths are lower than concrete block or brick walls.

• Structural guidelines exist for brittle unreinforced earthen walls

• When reinforced adobe, rammed earth, CEB have high strength and some ductility.

• Reinforced ICEB has some ductility, and cob even more

• Conventional earthbag has moderate ductility with low strength.

• Improved resilient contained earth (CE) has moderate strength with high ductility.
