Relative merits of grout and drainage curtains are given; effect of pressure on discharge in Lugeon-type water tests is considered; in certain cases, this discharge varies as fourth power of pressure; opening of joints under pressure effects can account for most of discrepancies observed between water test results and amount of cement injected; influence of cement grain sizes on groutability is mentioned; grouting pressures currently used in United States and Europe are discussed; effects of grouting and drainage on bank abutment stability are compared.
