Marina Renovation/ New Marina Construction
In the fall of 1987, the Sandusky Yacht Club retained our services to enlarge their basin and construct a new marina which included:
- 610′ rubble mound breakwater
- Dredging of 30,000 cubic yards
- Construction of 240 linear feet of steel bin breakwater
- 1,800 linear feet of stone revetment
Other Major Projects:
In the mid 80’s, we were contracted to reconstruct Battery Park Marina in Sandusky. The project consisted of demolition of the existing docks and stone filled cribs, closing the existing entrance with a sheetpile cell, excavation of a new entrance, construction of a breakwater extension and drilling and grouting of 15” diameter pipe piles into a limestone bottom for new floating docks. The project was completed in June of 1986.
Geotechnical Borings
Geotechnical borings and test borings are often required offshore to determine bottom soil samples prior to construction of large scale projects. Our barges are equipped with “through hull” drill compartments to allow easy set up for drill rigs aboard the barge.
We have supplied Geotechnical borings barges and crews for:
Cedar Point, the U.S. Coast Guard, the City of Sandusky, Quay 55, North Coast Harbor, ODNR (at Wildwood Marina), NEORSD (at Westerly WWTP), and various engineering firms.
Underwater Operations
We do underwater operations such as underwater inspections, repair, drilling and grouting, cutting and welding, and salvage operations.
In 1979, we successfully salvaged two 20’ diameter by 35’ high sewage treatment tanks belonging to the regional sewage district. These tanks had been lost during transport on Lake Erie when severe weather arouse. The search and salvage operation took two weeks around the clock. Once located, the tanks were recovered from a depth of 70’.

Boathouse Foundations
We were hired by a group of homeowners on Bimini Drive in Sandusky after a fire consumed their boathouses. Our scope of work included 3 phases. 1) Demolition & Removal 2) Surveying, dredging, new sheetpile bulkheading and backfilling for 33 homeowners 3) Construction of catwalks and fire walls for boathouses.
Dredging
We were secured by US Army Corps of Engineers to dredge near unexploded Ordnance which peppered the mouth of the Toussaint River resulting from testing and fireproofing artillery in the early 1900s. The project was to determine a safe and efficient means to dredge such materials. Blast protection shields were built and installed to protect the crew. The material was dredged by clam bucket and placed on specially constructed screens which were affixed to the tops of the dump scows. Then a high powered fire hose was used to sift the dredge material through a screen, leaving any ordnance atop the screen. Video cameras were used to monitor the screens. An ordnance team from Human Factor Applications, Inc. worked with our crew, handling and disposing of any ordnance found.
