It involves a technician actively monitoring the grouting procedures taking place, recording the relevant data, and assuring it meets the project requirements.

<p><p><h2>Project Summary/Scope:</h2><div>After the 1989 Loma Prieta Earthquake, sand boils and cracking were observed north and south of the east abutment of the Laurel Street Bridge in Santa Cruz, California. The bridge was designed and built in 1967 prior to when there was a good understanding for seismic design. Compaction grouting was chosen to densify the soils thus increasing the Cyclic Shear Resistance (CSR).
