Concrete dams, designed for flood-control, irrigation, or to provide hydro-electric power, have limited life spans and face severe pressures, stresses, and harsh operating environments. Spillways are subject to the constant flow of millions of gallons of water and enormous friction, and as a result, will erode over time.

When concrete on the dam, spillway, or basin erodes or deteriorates, it must be removed and repaired quickly and safely with minimal disruption. For that reason, Rampart’s hydrodemolition methods are perfectly-suited for both large-scale dam repair projects, like the Folsom Dam in California or the Canyon Ferry Dam in Montana, as well as smaller projects like the repair of the Quemahoning Dam in Pennsylvania. Those are just a few of the many reinforced, concrete dams that Rampart has helped repair.

Dam and spillway hydrodemolition can be performed in both dry and wet (underwater) locations. The concrete removal at the Canyon Ferry Dam was

performed 50 ft below the water surface  Rampart designed, constructed and operated our own special underwater hydrodemolition unit specifically for this project.  While it was difficult to take good pictures of this underwater process, we were able to record a short video.  Click here to view the underwater video.
