Shallow Foundations in Karst: Limited Mobility Grout or Not Limited Mobility Grout
J. E. Gómez, A. W. Cadden

Construction of shallow foundations in karstic geology always carries risks. In many cases, the perceived risks are high enough for the engineer to recommend alternative deep foundations or ground modification. The difficulties associated with construction of deep foundations in karst have led to the development of Limited Mobility Grouting (LMG) methods to improve the subsurface conditions and, in many cases, to permit the use of shallow foundations. This paper reviews the aspects to be considered for selection of foundation alternatives in karst, and presents three case histories where LMG has allowed the use of shallow foundations for major structures.
