LSC Storage Facility
Aggregate pier ground improvement for an existing warehouse
Subsurface Constructors installed 400 aggregate piers inside an existing warehouse on Long Island, New York that is being converted to a two-story storage facility. We used our innovative vibro flot system on a rig set up for working inside a building with height restrictions varying between 16 and 20 feet. The aggregate piers were installed to a depth of 10 to 13 feet to improve and reinforce loose fills and soft silts. This approach provided the project with significant cost savings from over-excavation of 10 to 13 feet below the existing building or pile foundations.
