Dam Spillway Blocks
Moving water through the spillway of a dam can cause erosion at the outlet, which can lead to the instability of the dam spillway.
Installing our Dam Spillway Blocks can reduce the undermining of the spillway, as well as damage to the stilling basin and erosion of the outlet channel and embankment material, which can ultimately lead to the failure of the dam.
Made to suit the requirements of the project, our precast wedge-shaped blocks use the hydrodynamics of the water flow to achieve stability in high velocity open channel conditions, this reduces both erosion and damage.
The Dam Spillway Blocks protect embankment dams and spillways, which are subject to high forces associated with overtopping flows, by using a concrete-step-overlay-system.
The downward weight (positive force) of the concrete block and the uplift pressure (negative force) of the flowing water, allow the system to remain stable, by preventing excessive acceleration of the flow and stopping the damage occurring from a high discharge velocity.
Designers must ensure an effective drainage network, by allowing water to be removed from beneath the system to safeguard the design of the overlay.
The Elite Dam Spillway system is a cost-effective, easy installation solution that can be installed in confined, hard-to-reach areas where large machinery is impractical or where there is an environmental impact within the surrounding area.
The concrete Dam Spillway Blocks are typically installed over site-specific filter fabric and subsequent drainage medium on a well-compacted surface.
