Sinkhole Rectification by Compaction Grouting

by Joseph P. Welsh, GKN Hayward Baker, Odenton, MD, USA,



Document Type: Proceeding Paper

Part of: Geotechnical Aspects of Karst Terrains: Exploration, Foundation Design and Performance, and Remedial Measures

Abstract:

The unraveling of the overburden by solution activity in karst formations has caused many problems in existing structures and has generated high foundation costs on new construction. Slurry grouting and deep foundations have sometimes solved these problems successfully, but with much concern due to the high costs and potential cost overruns in dealing with the unknown in these formations. The ability of compaction grouting to more predictably seal the limestone cavities and heal the damage overburden soils has allowed this technique to be used to solve karst sinkhole problems with a degree of economic certainty. Two case histories are presented describing compaction grouting utilized to provide economical solutions to foundation problems in new construction work in karst topographies.
