Underwater Unit

There is something fascinating about underwater hydrodemolition–using water, while in water, to remove concrete–but that is exactly what we do with this unit.

In addition, Rampart’s Underwater Hydrodemolition Unit is an excellent example of our ability to quickly design innovative and effective solutions to challenging engineering and removal problems. In this case, we responded to the requirement to remove a badly eroded spillway floor fifty (50) feet below the water’s surface!

Given the unevenness of the eroded floor, a diver located and leveled the unit, which was then operated by a Rampart field technician, who was stationed in a barge above.

Dive time is regulated and limited; so, our Underwater Hydrodemolition Unit is very effective way to maximize cutting speed, minimize diver fatigue, and successfully complete the work.
