Shallow dock? Shallow berth? Boat sitting on the bottom at low tide? We deepen residential slips, marina basins, commercial berths and canals — dredging technology used for precision, permitted end to end, and cut to depth by our own long-reach excavator, spud barge and push boat.
Ask a typical South Florida marine contractor to dredge your slip and you get whichever crew is free that week, on a barge borrowed from the dock job, squeezed in between pile driving and seawall pours. That’s why dredge schedules slip and customer get frustrated.
CMC by Marinus runs a dedicated dredging division — its own crew, its own equipment, its own survey workflow — and dredging is the only thing it does. When you call about a shallow slip, you are not getting the leftovers of a dock or seawall schedule. You are getting the people whose entire job is moving the bottom.
Dredging is its own line of business here, with its own estimator, project management and permitting pipeline. It never competes internally with a dock or seawall backlog for attention.
The same operators, deckhands and survey tech run every job. They read a bucket by feel, they know what South Florida's bottom to a cut, and they aren’t learning it on your slip.
Spud barge, long-reach excavator, push boat, bins and turbidity gear stay rigged for dredging. Nothing has to come off another project, so mobilization is a phone call — not a queue.
Because dredging is all we do in this division, we’ll tell you when you can expect a cut. A generalist chasing a slow month usually won’t.
We sound your slip and build a bathymetric model in Dredgemagic. You see exactly how shallow it is and how much material has to move.
Drawings, application and agency correspondence handled end to end — federal, state, county & city. You sign the owner authorization and we take it from there.
Turbidity curtain in, barge spudded down, long-reach excavator cuts to design depth. Material is loaded to sealed bins and hauled to an approved upland site.
Post-dredge survey against the permitted cut, as-built handed over, site left clean. Then you put the boat back where it belongs.
Slips we’ve already deepened.
Yes — dredging in Florida waters requires federal, state, county & city authorization, even for a small residential slip. We handle the whole path end to end, so the only thing you sign is the owner authorization.
The dredging itself is usually the short part — a residential slip in the 20–100 CY range is typically days on site once we mobilize. Permitting is the long part, so start that conversation early.
To whatever depth your permit allows. Our long-reach excavator working off a spud barge handles the depths typical of Miami-Dade canals, slips and berths — and our dredging technology program keeps the cut inside the permitted envelope.
Yes. Florida certified general contractor CGC #1540011, fully insured, and owned & operated by a Texas A&M Maritime Academy graduate holding an unlimited tonnage U.S. Coast Guard license.
