GMI performed compaction grouting operations on an emergency sinkhole repair project for Caltrans.  This particular sinkhole ran across all lanes of southbound traffic and two lanes of northbound traffic along a section of I-880 in San Jose, Ca.  Safety was the number one priority on this project since the work was being performed next to a force main for the City of San Jose.  Compaction grouting was used to densify soil and re-level settled portions of the roadway
