There are two methods of dredging employed by AE Commercial Diving Services: hand dredging and hydraulic dredging.  Only after a site visit can our specialist best determine which method is best for your project.

 

Hand dredging is labor intensive and time consuming.  It is very effective, however, for smaller more-precise projects where a machine would simply not be adequate. In hand dredging, a diver guides a dredge-tipped suction hose towards the debris and, using various techniques, guides the targeted sediments up the suction hose to the dewatering bag or site.

​

Hydraulic Dredging is more effective for larger scale projects in locations  where hand dredging is not feasible and excavation is impossible.  The principal is the same, only a mechanical arm guides a dredging tip rather than a diver.  Unlike traditional dredging barges or watering vessels, our hydraulic dredge is powered and operated from an amphibious machine made in Sweden called the 'Amphibious Tool Carrier' or ATC.  For videos showcasing the ATC, go to our 'Videos' page.

​

Because the Amphibious Tool Carrier moves on tracks, we are able to move our hydraulic dredging system safely across lawns, fields, and marshes into the body of water's target area with little impact to the transit areas and environment.  This is ideal for those looking to complete large scale dredging projects in areas that would be otherwise damaged by heavy equipment such as excavators, or is inaccessible by these machines.  

​

Also, the variety of attachments available for the ATC make it a versatile option when removing larger objects that cannot be removed by dredging, such as large stones, branches, some nuisance species, and other submersed items.
