Commercial Diving


Over 35 years ago, Inner Space Services Inc. started as a commercial diving company and then quickly grew into a full service Marine Construction and Hydraulic Dredging company.

We are still out doing the diving ourselves. ISSI has held the Underwater Maintenance and Services Contract for the Commonwealth of MA, Department of Conservation and Recreation (formerly the MDC) for most of the past 30 years, performing inspections, maintenance and repairs to all their facilities including all the major locks and dam systems, piers and pipelines to recreational islands.

ISSI performed for many years underwater jobs: Installing valves, gates, trash racks, piping and pipelines for municipalities, pulp and paper industry and power generating plants.
