Our hydraulic dredging equipment has a cutting head to dislodge sediment which is then immediately suctioned through the pump ladder. This diluted sediment, or `slurry´, is then pumped through a flexible, floating pipe to a covered floating barge, or directly to an on-land dewatering site, where the sediment is allowed to settle out of the water and then the spoils can be removed or repurposed.
Our long arm excavators or waterborne barge mounted excavators use a set of mechanical arms with a bucket attached at the end to dig material from the bottom surface and dump the material into a land based stockpile, container or onto a barge to be transported.
Often time’s sediments reclaim previously dredged channels, waterways, and channels. Our services range from restoring one personal boat slip to an entire community’s waterways back to a navigable condition. We also perform maintenance dredging services at drainage canals, bank stabilization, weed and trash aqua harvesting. These efforts can be accomplished hydraulically or mechanically depending on site requirements and conditions.
Environmental dredging is used to remove contamination from targeted areas. This technology is very precise and is designed to minimize resuspension of small sediment particles that may be contaminated with PCBs, heavy metals, or other toxic materials. This process is much more controlled than navigational dredging, using our hydraulic dredge, which functions like a large vacuum cleaner to remove contaminated sediments which is then pumped to a dewatering geotextile tube for removal.
Permit acquisition can be a complicated process that often involves a great deal of research and formalities. Five Dredge & Marine will expertly manage all required due diligence, agency correspondence, and inspections that go along with proper permitting. Our goal is to make dredging and marine construction projects smooth and efficient for our clients.
Marine permits in Florida are handled on a case by case basis by Five Dredge & Marine to make sure each customer has the proper licensing, authorization, and documentation for their specific project. Most cities and municipalities require environmental, state, army corps, county, and city permits. The process to obtain permits ranges from 2 – 12 months depending on the projects requirements.
Our permitting department has a solid working relationship with all the necessary permitting agencies. We also ensure all work is in accordance with the stringent environmental rules and regulations that govern the dredging and marine construction industry.
