Maximize strength and ductility 

Enough strength

without too much steel 

Earthen walls rely on stability and are reliable even without strengths comparable to concrete block or brick walls.

• What structural guidelines are there for brittle unreinforced earthen walls?

• Reinforced adobe, rammed earth, CEB all have high strength with some ductility.

• Reinforced ICEB can have moderate ductility, and cob even more

• Conventional earthbag has moderate ductility with low strength.

• Improved contained earth (CE) detailing delivers moderate strength with high ductility.
