The SAFB’s success can be attributed to its’ simple yet ingenious approach to flood defence, using the advancing floodwaters to automatically raise the barrier; effectively using the problem to create a highly effective solution. As well as activating automatically, the SAFB DAM can also be activated by the means of an inflatable airbag remotely operated by a push switch or telemetry system. The DAM allows the end user to have full control over the barrier, enabling deployment in any situation, from pre-empting a storm to routine maintenance checks.
Whilst in its resting position, all operational parts of the barrier are invisibly concealed in the underground basin, sheltering seals from the elements. When the floodwater has risen to within 10cm below the pre-flood level the basin, housing the floating wall, starts to fill up prompting the barrier to rise and become fully deployed. A similar concept is adopted with the use of DAM; rather than using the power of incoming floodwaters to deploy, air is filled into the inflatable airbag replicating the pressure required for the barrier to deploy into position.
