Drop-Down Flood Barriers

When not in use the drop-down automatic flood barrier is unobtrusively located above the head of the opening, ready to be lowered at a moment’s notice.

Automatic sensors can operate the barrier with rising floodwaters, or with push button operation for complete control. Direct drive electric motors smoothly and precisely lower the barrier in to position and firmly lock it in to place to form an efficient, dependable flood defense.

The barriers work on dead level thresholds and require no excavation or civil works to install.

Drop Down Flood Barrier Safety

Safety is a key factor in this design and all motors have a ‘free-fall’, dead-stop braking system built-in as standard. In addition, all systems are installed with a pulley system that overrides the motorized drive and allows the flood barriers to be manually lowered and raised in safety.

As optional features, the systems can be activated remotely, triggered by water or smoke detection or by security alarm systems. Touch and motion sensors can also be added to the braking system whilst further security is available in the form of audio/visual alarms, warning as the flood barrier moves.

A 24 volt back-up system ensures that the flood barrier will operate in the event of a mains supply failure.
