Earth dam grouting technology is an innovation for seepagetreatment of earth dam and embankment. Grouting Technical Specification for Earth Dam was issued in 1988, and it has played animportant role in application and promotion of earth dam groutingtechnology. Many reservoirs and embankments were reinforced byusing the technology. Meanwhile the technology has obtainedimprovement and development in practice, and the application rangeand the scale of treated projects have extended. In combination withthe current development of earth dam grouting technology, thisStandard is prepared through the Supplementary and revision of theformer standard.
