This report reviews five low vibration ground
improvement techniques suitable for remedial work near
existing structures. The five techniques are:
compaction grouting, permeation grouting, jet grouting,
in situ soil mixing, and drain pile. The factors which
can influence the effectiveness of each technique are
identified. Cost estimates are given for each
technique, except the drain pile technique which is not
yet available in the United States. Nineteen case
studies of liquefaction remediation and remedial work
near existing lifelines are reviewed. Advantages and
constraints of the five techniques are compared. A
combination of techniques may provide the most
cost-effective ground improvement solution for
preventing damage to existing lifelines resulting from
liquefaction-induced horizontal ground displacement,
subsidence, and uplift.
