Once the SCFB™ has been installed, the floating entrenched wall consisting of polyester is practically invisible under normal water level conditions. The wall is reinforced by laminated steel strips and protected by Kevlar for impact strength. On top, a steel lid locks in the entrenchment space under normal (non flood) conditions.

Once the water rises to approximately 10 cm beneath the flood level, the basin of the barrier fills up through a filling-pipe in a pit. The polyester wall rises and floats. As soon as the basin is totally filled, the closing surface will “lock” the barrier into a watertight position.

Now the water can rise further without flooding the protected area. Once the water level subsides to a normal level, the basin is drained through a drain pipe with non return valves or by a pump. Once the water has left the basin, the wall returns to its resting position within the basin. The lid on top of the wall then closes to prevent the inflow of waste or debris.
