A Review of Drilling and Grouting Methods for Existing Embankment Dams

by Donald A. Bruce, Nicholson Construction of America, Bridgeville, United States,



Document Type: Proceeding Paper

Part of: Geotechnical Practice in Dam Rehabilitation

Abstract:

With the increasing emphasis being placed on dam rehabilitation and repair, more dam engineers are faced with the need to interface with drilling and grouting specialists. Regretfully, it is often the case that these specialists execute their work rather better than they explain their intentions, especially at the pre-award stage. This may lead to personal conflicts and professional disputes during the work, and so an unwillingness among dam engineers to entertain drilling and grouting techniques as favored options for future problems. This paper provides generic classifications of drilling and grouting methods and materials for both rock and soil, so that the non-specialist can have a basic framework of reference. An extended bibliography is provided so that readers can research particular points of interest.
