The Dutch Float Dike is a self‑activating system. As the water level rises, the buoyant force pushes the gate upward, creating a solid flood barrier. The system can be designed so that once the closing water level is reached, the basin fills and the gate moves into its closed position in one smooth motion. This prevents the gate from “dancing” during activation.

When the water rises above the closing level, the gate is already fully closed and will hold back the rising water. The maximum dike height is 4.5 meters.

After the high‑water event, when the water level drops below the closing level, the basin will empty again if there is sufficient gradient. The gate will then return to its horizontal resting position in one motion. If there is insufficient gradient, the basin may need to be pumped empty.
