Building with Adobe
• mud plus sometimes straw, manure, or hay were mixed together to make adobe bricks
• the mixture was then put in molds and left outside to dry in the sun
• adobe bricks don’t permanently harden, so they shrink or expand like a sponge, depending on how much moisture is around them

Adobe Deterioration
• water - makes adobe putty-like and can possibly wash it away
• plants - roots grow into the adobe bricks, which causes cracking
• pests - eat the adobe and make homes in the walls
• wind - erosionhttp://www.nps.gov/history/hps/tps/briefs/brief05.htm

Restoration and Maintenance
• major renovations were finished in 1917, 1920 and 1995
• roof and walls have been reinforced with steel to make them stronger

Why the mission still stands today
• earthquake survival – having thick, relatively short walls (4 ft. thick, 22 ft. tall), makes it very stable and hard to knock down
• general longevity – the site most likely has good drainage, which keeps the adobe dry and stable
