Monitoring Program for Cement Grouting of Underground Karst Cavities

“…The cause of the sinkholes had been attributed to the dissolution of the limestone bedrock and subsequent raveling of the overburden soil cover into the underlying Karst cavities. Accordingly, treatment methods were recommended to minimize the recurrence of the sinkholes composing of filling the underground cavities by injecting cement grout at depths varying between 32 to 60 m in a pilot area and by eliminating the possibilities of collapse of the upper level Karst cavities within the limestone bedrock [5]. The pilot area located in Sector A1 of the residential area classified as the evacuated area ( Fig.…”
