What is the purpose of dredging?
Dredging is used to create, deepen and/or widen a channel, berth, harbor or other waterway. Dredging allows larger vessels access to piers and berths, thus expanding markets. Dredging can make waterborne transportation more efficient and plays a vital role in the economic development and environmental aspect of most countries in the world. Beaches suffering from erosion can be replenished by the use of a dredge. Marshes can be created by hydraulically placing dredged material, thus improving the aquatic habitat of many species. Dredging removes sand, sediments, silts, fines and sludge from the bottom of any waterborne environment. The material is then removed via the dredge and pumped or mechanically moved to a disposal site through pipelines or barges.

Can you do an onsite inspection?
Yes, depending on the project.

Do you offer consulting services if we choose another contractor?
No.

To what depth can you dredge?
We can dig as deep as 65 feet with a hydraulic dredge and over 120 feet with a clamshell dredge.

How do we begin the process to discuss our dredging needs?
You can call us, e-mail us or you can reach us on our website. We will then follow-up with you to discuss your needs, determine solutions, costs, and your timeframe.

How long does it take to move in and begin dredging.
If the proper permits are in place, we can get started approximately 10-14 days after agreeing to use our service.

How do I obtain a permit?
One of the first places to review prior to hiring a dredging company is to review information pertaining to a dredging permit. A good place to start is the Corps Regulations, Administrative, and Policy Materials page from the US Army Corps of Engineers website. It may be advisable to contact a survey or engineering firm to assist you with this process.

How much does dredging cost?
Costs are based on the scope of work involved and are influenced by type of material, amount of material, distance to the disposal area, weather concerns, vessel traffic concerns and other influences. Each request must be individually evaluated to determine the cost of that particular operation.
