Jetties & Sea Walls

Bulkhead Upgrade

This project highlights a new vinyl bulkhead installation over in Cotuit. The wall is over 180’ long and made up of  ShoreGuard vinyl sheet-piling, and Chance helical tie back anchors. After the new wall was installed and all the fastening complete, the wall was backfilled with over 150 cubic yard of clean compatible fill material to re-nourish the heavily eroded embankment. All wall construction mobilization and installation had to be done by water, however, all of the new fill material was brought in from the upland side of this project and installed using a chute system. This was done to confirm there would be no further disturbance of the embankment.

Sea View Stone Revetment

This project was a total upgrade for this property’s beachfront. This project included 180 feet of revetment reconstruction using a combination of the existing armor stone and new armor stone, and a 4’ increase in the top of wall elevation. In addition to the fortification of the wall, 2,200 cubic yards of beach compatible nourishment sand was installed to provide a buffer area between the seawall and the ocean. The stone groin projecting out into the water were completely reconstructed to help retain the sand from laterals erosion. Lastly, an embankment staircase and deck area were upgraded and reconstructed using wedge anchor to anchor the structure to the new revetment and finished with IPE Hardwood decking and handrail material.
