Automatic Hydraulic Flood Barrier
A self-closing, non-electrical automatic flood defence system
The Hydraulic Barrier is a passive flood defence measure which is highly suitable for rapid onset flooding, when there is little time to deploy manual measures.
The system can either be embedded flush into the ground or surface-mounted.
In the event of a flood, when water flows into the lower part of the water defence door leaf and reaches a trigger value, the buoyancy pushes the front end of the water defence door leaf up to achieve automatic water defence with the rising water.
A warning light flashes each time the barrier is activated to warn the onset of pedestrians or vehicles.
Prior to a flood event, the barrier can also be opened manually and locked into place.
