Passive self-closing flood barrier uses floodwater to raise it into position

From Superinnovators 01/12/23

Dutch company Hyflo manufactures a patented Self Closing Flood Barrier system that uses floodwater and buoyancy to raise it in to position – once the water has gone the barrier descends back into the ground.

One of the earliest deployments was in 1999 at a pharmaceutical factory in Netherlands, with Hyflo established in 2014 to redesign the system for mass production.

The barriers range from 30cm to 2.5m in protection height and multiple sections can be installed to fit any length.

The company details 29 installations globally on its website with one of the latest installed in 2018 at a house in the UK.
