Dam spillway blocks are a concrete-step-overlay-protection system for embankment dams and spillways that are subject to high forces associated with overtopping flow.
The downward weight (positive force) of the block and the uplift pressure (negative force) of the flowing water allow the system to remain stable. An effective drainage network – allowing water to be removed from beneath the system – is essential to the design of the overlay.
