How do ‘passive flood barriers’ self-deploy?

Floodwater can rise fast, and when it does, there isn’t always time to rely on manual deployment.

That’s where FloodFree’s range of Passive Flood Barriers comes in.

Passive Barriers are self-deploying, meaning they self-actuate or “pop-up” as floodwater levels rise. The system operates on the simple but highly effective principle of buoyancy.

As flood or storm water fills the barrier’s adjoining drain, the rising water level causes the barrier to lift into position, sealing the isolation point and forming an effective flood protection barrier across access points, including pedestrian walkways, driveways, and building openings.

In this video, the principle of buoyancy is demonstrated by a team member applying force to the barrier. Even when pushed down, the barrier instantly returns to its upright position, demonstrating that flood protection is active the moment it’s needed.
