Due to the increasingly prominent issue of detachment of exterior wall facing bricks in recent years,how to accurately determine whether there are defects in exterior wall facing bricks and the scope of defects is a key factor in preventing and repairing exterior wall facing bricks.This paper takes a certain project as an example,and uses appearance inspection method,direct tapping method,and infrared thermal imaging method to detect the defects on the exterior wall.Through exterior wall structural inspection and material bonding strength testing,the scope of hollowing and existing defects of the exterior wall facing bricks are comprehensively judged,so the causes are analyzed,which provides technical basis for subsequent repair projects or taking measures to prevent the detachment of facing bricks.
