Understanding Dredging
All waterways, channels, and canals experience constant silting caused by stormwater runoff, erosion, and organic deposits called “Sediments.” Some inlets and waterways have the benefit of faster moving currents which help keep the passages clean. Others suffer as the deposits of sand, silt, and organics collect, making the water shallower. When this occurs, boat travel or even entry to your dock can become difficult as the water becomes too shallow for your boat and motor. When the waterways are no longer navigable, a process called “Dredging” is required. Dredging removed the built-up deposits of sand, silt, and organic from the bottom of the waterways. Typically, a dredge can remove the material up to its original depth initially permitted or excavated by the Army Core of Engineers (ACOE). PMC obtains the required engineering information to prepare and obtain all required permits.
Mechanical
A mechanical dredge is the most common method to perform small waterways, canals, inland channels, and dock areas. A mechanical dredge utilizes a backhoe or crane, which physically extracts and removes the material one scoop at a time. Once you remove the sediments, the excess water drains off, and the material is placed in a lined container or truck for disposal at an approved facility. Mechanical dredges require heavy equipment placed on a barge or the shoreline, and a skilled operator carefully removes the material to the proper depth.
