Confined masonry is one of the most common building systems in the world, with millions of structures built this way. The first confined earthbag house is now under construction in Ecuador.
Confined masonry construction consists of unreinforced masonry walls confined with reinforced concrete (RC) columns and RC bond beams. In Mexico, where confined masonry makes up over 60% of all structures, it is used for lowrise construction and for buildings up to seven stories high. Confined masonry housing construction is practiced in several countries that are located in regions of high seismic risk, including Mexico, Slovenia, Chile, Peru, Argentina, Serbia and Montenegro. Columns and beams are cast-in-place after the earthbags are placed to help tie the wall together.
