Geological and Geotechnical Aspects of Grouting in Karst
Our last paper presented in 2003 at the Third International Conference on Grouting and Ground Treatment, Grouting in Karst Terrane - Concepts and Case Histories, described the effects of variations in karst origins on the efficacy of the eventual grouting concepts adopted to remediate a variety of sites in the eastern United States. This paper describes a number of case histories of karst mitigation wherein a range of grouting methodologies were used with a wide range of success, demonstrating the need for as complete an understanding of the geological and geotechnical characteristics of the site's subsurface as possible. The sites described are located in regions of the eastern United States underlain by Proterozoic (Precambrian) to early Paleozoic carbonates of the Appalachians and Valley and Ridge. Rock types vary; faulted and folded marble, dolomite and limestone all in varying stages of weathering and dissolution. The authors have used a number of techniques to resolve karst hazards in the complex geologic conditions of the eastern U.S. The authors have also reviewed a number of projects in a regulatory capacity where mistakes, both of a technical and economic nature, have been observed. Case histories are presented that relate differences in approach of investigative techniques that vary from comprehensive and relatively expensive to "bargain-basement" and relatively inexpensive. Approaches vary from soil grouting, hybrid grouting of soil/rock interfaces, compaction grouting and slurry grouting. This paper reviews several case histories relating to roadways, detention basins and general building construction to illustrate the successes and failures of the different approaches.
