Commercial & Residential Dredging

Serving the Northeast Coastal Waterways and Lakes

Strategically located in Newington, NH, Riverside & Pickering Marine Contractors is ideally positioned for commercial and residential dredging projects throughout the Northeast. Coupled with our knowledge of industry standards and environmental regulations, our team’s years of dredging experience in the coastal and inland waters of New England has given us a strong understanding of what it takes to complete challenging projects in winter conditions and tidal waterways.

In addition to our expertise in the general marine construction industry, Riverside & Pickering has more than 75 years combined experience in marine support, logistics and floating marine operations. As all of our work is performed in the New England area, we are accustomed to tidal ranges up to 13 feet and have extensive working knowledge of the local waterways. We have learned the intricacies of dredging in the region during restricted and non-restricted permit conditions, including the challenges of dredging on lakes and ponds during the winter months.

Our dredging services include the following:

Far-shore and near-shore environmental clamshell bucket dredging

Freshwater dredging in ponds and lakes

Dredged material dewatering, amendment, transportation and disposal

Turbidity control systems

Dredging in depths up to 65 feet

Marine support for tugs/barges in dredging operations
