Beach Restoration
|
|
Sand is first hydraulically dredged from the dredge site and transported via pipeline to the restoration area. There the dredge materials are deposited and later graded and planted with grass. |

Trenchless Pipe Replacement
|
Pipebursting is a method of Trenchless Technology where old, damaged pipe (sewer, water, gas or other production pipelines) can be replaced with "size for size" or "up sized" new pipe, all without having to dig it up. The pipebursting tool is inserted into the old pipe through a small insertion pit, travels through the old pipe, bursting it as it goes, and pulling the new pipe in place behind it. Inner Space Dredging Services, Inc. was the first contractor in New England to use this method. |

The trenchless tool burst the old pipe that ran beneath this marina building simultaneously replacing it with the new PE pipe. Concerns of tool vibration damaging the old structure proved unfounded.
The cast iron pipe incorporated cement sealed joints, which were easily burst. |
