Resin injection has long been used internationally for the lifting or ‘level correction’ of buildings. For this purpose, expanding resin mixes are injected into the ground at relatively shallow depths,
resulting in ground heave and building lift. It is logical to expect that this resin injection and expansion process also results in compaction or densification of the ground (in a similar way to
compaction grouting). As such, resin injection can potentially be used to mitigate liquefaction or for other applications where ground densification is required.
The aim of this study is to examine whether resin injection is a viable form of ground improvement, primarily for liquefaction mitigation.
