Given the presence of dense, bouldery glacial till from approximately 20-30 feet below ground surface, permeation grouting was selected for groundwater control to bedrock beneath Posillico’s structural secant pile excavation support for the new 46th Street Vent Plant in New York City. Jet grouting was also used to close gaps around a water main that traversed the excavation.
