Abstract: Logan Martin dam on the Coosa River in Alabama has been plagued by underseepage since its construction in 1964. The karst forming the dam's foundation allows water to flow under the dam at depths as great at 131 m. Alabama Power Company, owner of the dam, began a deep grouting program in 1991 to halt the seepage. Because of the great depths and varying geological conditions involved, the company developed special drilling procedures and grout formulations for the project.
