Some Considerations for Remedial Grouting for Seepage Control

by Kenneth D. Weaver, Woodward-Clyde Consultants, Oakland, United States,



Document Type: Proceeding Paper

Part of: Geotechnical Practice in Dam Rehabilitation

Abstract:

The inadequate performance of grout curtains and the consequent need for remedial and supplementary grouting of dam foundations probably arises, in essentially all cases, from a combination of factors. A detailed review of the project records in conjunction with an examination of the geologic conditions is likely to reveal deficiencies that can and should be corrected by means of remedial and supplementary grouting. Unfortunately, it sometimes is assumed that inadequate performance of a grout curtain demonstrates that adequate grouting cannot be accomplished at the site, and more drastic (and expensive) remedial measures are selected. Although this may be economically and technically inappropriate in many cases, the problems associated with accomplishing remedial grouting in an existing dam can be substantial, and they increase with depth to the point that other methods of seepage control become more attractive.
