HYFLO was established in January 2014 to set up the production for the Self Closing Flood Barriers (SCFB™) to meet the growing requirement for global solutions to extreme flooding events and to establish the highest possible quality for all the components. Therefor all the components were redesigned by Hyflo civil engineering specialists and there are subjected to strength calculations and various tests. In total the SCFB™ underwent in excess of more than 70 tests; these tests included static load, dynamic load, buoyancy force, sand-, gravel-, duration (35 days) extreme cold temperature-, earthquake- and obstruction-tests. These tests concluded that the barrier never stayed stuck and rose up in all tests. The SCFB™ remained watertight in all tests. The SCFB™ is made of very durable materials designed to at least for 50 to 100 years and remains virtually maintenance free of many years.

The SCFB™ can be built at any required length: 1 m - 10 m - 100 m - 1000 m and more. To meat all the requirements Hyflo will make every barrier to fit. The wall is fabricated in nominally 1 m lengths with a close tolerance. The floating walls are connected to each other with a special designed reinforced rubber and stainless steel 316 mounting strips. The basin from the Self Closing Flood Barrier can be built out of concrete or steel. Depending on the requested length and location the Hyflo dealers can advice what the best option is for this location and if a service pit is needed. Hyflo and the dealers can help and support local architects and civil engineers with the necessary calculations and drawings.   

HYFLO Production

All the components of the SCFB™ are produced in the Netherlands and are recorded and tested. One of the main components of the SCFB™ is the floating wall. This floating wall consists of a foam core with a fibreglass outer layer. The wall are reinforced with composite profiles and woven fibreglass and is fabricated in a special designed mold that the floating walls can be made out of one piece. This combination give the wall extra strength and makes it very light. Because of the unique design each section can resist at least three times the maximum water pressure.
