HYFLO Passive Self Closing Flood Barriers
The Hyflo SCFB™ is a Passive device that harnesses the power of floodwater to raise the barrier, effectively using the problem to create the solution. Flash flooding scenarios limit the time available to deploy manually operated flood gates and demountable systems that are typically stored off site and require human intervention to assemble. The Hyflo SCFB™overcomes these limitations of manually deployed flood defences, and has the considerable advantage of not requiring any manpower during a flood warning, which would otherwise put lives at risk.
With a design life of 100 years, and requiring minimal maintenance, the Hyflo SCFB ™ is not only an extremely effective flood defence system, but it makes a strong economic case too. Minimal operational costs give the Hyflo SCFB ™ a distinct advantage over other systems in terms of ongoing costs.
When not in use the barrier is protected underground and its seals are sheltered from the elements. With an unblemished 100% deployment success record the Hyflo SCFB™ is a prime consideration when specifying a flood defence that is cost effective and passive - (no people, no power).

Principle of the Hyflo SCFB™
1.
2.
3.
Following installation and in non-flood conditions, all operational parts of the barrier are invisibly concealed in the ground inside its basin.
When floodwater rises to within 10cm below flood level, the enclosed basin, which houses
the floating wall, starts to fill up through an inlet pipe from the adjacent service pit.
The flood wall floats and rises. When the basin is totally filled, the angled support block will lock the barrier into position making it watertight.
The floodwater can now continue to rise without flooding the protected area.
As the water subsides , the flood water in the basin is drained by drain pipes with one way check valves.
As the water continues to drain from the basin, the flood wall returns to its resting position within the basin and the lid seals the barrier to protect the barrier from waste and debris.
Innovative, effective and proven defence.
This award winning concept has been acclaimed as the world's most effective protection against floods. The Self Closing Flood Barriers SCFB™ have now become the leading flood defence device in its field. It has been in operational use around the globe since 1998 with a 100% success rate.
