FloodBreak is essentially a buoyant composite beam placed at the entrance to a driveway, doorway, or other potential flood path. The barrier hinges into a recess in the pavement immediately in front of the entrance. Its normal position is down, allowing full-time protection without affecting traffic or otherwise changing the look and feel of the area. The barrier's surface finish can be matched to existing decorative elements as required.
When water rises and approaches the entrance, FloodBreak floats and rotates upwards. The hydrostatic pressure of the backed-up floodwater pushes the barrier closed and seals it against a rubber flange. Once a flood has begun, the barrier will be held shut by the water and cannot be opened until the water recedes, when FloodBreak returns to the lowered position, opening the entrance once again.
