National Marine And Diving Services Focuses on Underwater Construction.
Diving for Construction

Underwater Repair
and Restoration.

Diving for construction requires a highly qualified and certified supporting specialist, with both advanced education and field experience.
Employing a commercial diver to support the build of your underwater structure means that you’re employing two professionals in one:
a certified diver and
a building subcontractor.

Building And Restoration Services We Provide.

Bridges & Dams

Diving for construction is no easy task. To assist in the build of a submerged structure, the commercial diver must complete the same job as your average above sea-level subcontracted laborer—except in conditions that compromise vision and stability, among many other factors. In other words, when it comes to underwater contracting, your best bet for a safe and satisfactory subcontractor is hiring a long-standing company with a track record of success —the more experience, the better!


To build a bridge that spans a body of water, a partially submerged support system of piers must first be put in place. There are many methods for achieving this goal, most of which require a commercial diver who can support the structural engineering details and work with the composition of the submerged foundation.


The purpose of the dam is to stop the flow of water; but how do you build a dam in the flow before it’s stopped? NM&DS can  provide assistance in accomplishing this feat and help bring your dam construction project to successful completion.


Peirs, Docks, Wharfs,
Intakes and Outfalls

Piers, Docks, and Wharfs
Underwater support for marine structures such as these calls for intensive underwater labor and a certain level of know-how on the way in which each component works to support the structure, as well as the sequence in which the components must be placed for build. The result is a safe and sound on-water edifice that can support traffic and a multitude of end-user purposes.

Intakes and Outfalls
Any facility that requires a water supply system or network, such as power plants or water treatment facilities, will necessitate both intake and outfall structural components that retrieve and dispense of water from and to various natural sources, such as lakes, rivers, groundwater, or the ocean. The intake component is an above or below ground raw water collection point, and the outfall component releases water back to its natural source. Our team can provide assistance in the construction of each of these components.


Pipeline, Diving & Building

Any facility that requires a water supply system will demand a network of pipelines built for conduction. A sealed pipeline system is essential for the successful transfer of water from one point to another, and installing pipeline in an underwater environment is a task that calls for expert diving contractors.

Diving for construction demands skill, experience, and dexterity—all key traits of an exceedingly skilled and experienced commercial diver hired for the build of an underwater structure. The team of commercial divers at National Marine & Diving Services, Inc. possesses thes traits and so much more.
