Abstract : Glen Canyon Dam is founded in the relatively pervious Navajo sandstone geological formation. Although flows from drain holes drilled during construction of the dam are somewhat less than anticipated in the designs, the wide variation of permeability of the sandstone as determined by laboratory tests indicated a possibility of higher than expected flows through localized zones higher in the abutments. Since the capabilities of several chemical grouts as sealants in this type of rock had not been previously evaluated by testing procedures, a laboratory program was initiated. Several types of grouts were investigated, and tests, results, and conclusions derived from laboratory work are presented. The grout field trials which were initiated at the conclusion of the laboratory investigations are also presented. Results of chemical, petrographic, and physical investigations on the natural and chemically grouted Navajo sandstone core drill samples will be presented in a supplementary report. (Author)
