ABSTRACT
The world of grouting is truly and indeed wide, as illustrated in a succession of recent conferences and textbooks. Paradoxically, the grouting techniques used in the United States to remediate existing dams and levees are surprisingly few, even though their annual dollar value has reached extraordinary levels in recent years: industry reviews and estimates put this gure in the $80-$100-million range in each of the years from 2006 to 2010. It is, of course, highly debatable if that level of intensity can and will be sustained in the years ahead, and indeed the debate is most likely to be lost. As introduced in Chapter 1, the current phase of dam and levee remediation represents an unparalleled intensity of activity in specialty geotechnical construction circles in the United States and it may well be unprecedented in any country so far.
