Self-closing flood barriers

The barriers are usually located in an underground steel or concrete tank, positioned vertically. The barriers consist of a rigid foam core and a GRP outer layer. When floodwaters rise to a predetermined level, water overflows into the service pit and then into the tank through pipes, allowing the barrier to float and fully rise. When the tank is filled with water, the inclined support blocks lock the barrier in place, sealing it and making it waterproof. The barrier is now fully effective and waterproof to its entire height.

As the floodwaters recede, the barrier is lowered again to its resting position. The tank can also be drained to lower the barrier before the adjacent groundwater level has completely receded.

Self-closing barrier features:

No energy required – operates even in the event of a power outage

No labor required – automatically deploys

No storage required – in the resting position, the SCFB is invisible and completely self-protecting underground

Short closing time – only deployed in the event of flooding

Low operating costs – high quality components; simple inspection
