were loaded while simultaneously injecting grout under the other footings. This prevented the stai rs from separating from the rest of the building. After completion of compaction grouting and push pier activities, polyurethane grout was injected under each of the foundations to address any voids created from lifting and to minimize the potential of post-lifting settlement. Surveys completed after the grouting program revealed no additional settlement of the structure on any of the footings. Conclusions The stabilization and lifting program utilizing low mobility compaction grout on two very di fferent types of structures in different soil profiles highlights the adaptability of this technique when correctly executed. Proper evaluation of the structure and soil profile will allow the grouting contractor to identify the compaction grouting sequence to effectively s t ab i l i z e and l i f t a s t ruc t ur e . Additionally, adjusting the grout mix and injection rates in real time based on in situ conditions; implementation of a quality monitoring program prior to, during and post remediation; and realt ime mode l ing of the data are instrumental in a successful project. Compaction grouting provided an economical, controlled approach to mitigating the problem soil areas and reducing the risk of future settlement.
