Why does the flood barrier float?
The FloodBreak passive flood barrier is actually a buoyant panel constructed of hollow aluminum extrusions. The extrusions are designed to be structural while also providing excellent flotation. Additionally, the extrusions are chambered so that even if an area of the panel is compromised, the overall panel will still float. This is similar to the design of a ship’s hull, where bulkheads protect the ship even if the hull is locally damaged.
As the floodwater fills the gate pan, the hydrostatic pressure lifts the flood barrier and continues to raise it as the floodwater continues to rise. The buoyant flood barrier floats on top of the water. There is no need for human intervention or power to deploy the FloodBreak Automatic Floodgate. See How It Works
How much does the floating panel weigh?
The actual weight varies depending on the type of gate, size and any special coatings or surface treatments specified. We design the cross-section of the gate panel to ensure that the total weight is always less than the water it floats upon and include a factor of safety to ensure this. Every floodgate is certified by an independent professional engineer who ensures that the floodgate is designed to successfully deploy.
