Abstract: A red mud storage yard of China Aluminum Guizhou Co. is located in a karst terrain. The alkali solution from the red mud requires seepage cutoff design to prevent leakage to the karst rock fissures. This design is the first jet grout case history reported by using conventional portland cement slurry in the karst environment for the seepage cutoff design for strong alkali solutions.
