Raising the bar on an Ohio Dam

Increased capacity for a fly-ash reservoir.

Inside the Project

This project consisted of raising the existing Earthen Dam using precast concrete mechanically stabilized earth (MSE) wall panels and vinyl sheet piling (VSP) as a cutoff wall. The VSP was installed at a depth of 30 feet through a bentonite slurry wall that ran the entire length of the dam. The dam raising was approximately 1,600 feet long and 13 feet high. This project also included the construction of a mile long access road, existing spillway and spillway inlet raising.
