Self Closing Flood Barrier

WORLD MOST EFFECTED FLOOD BARRIER

The Self Closing Flood Barrier SCFB™, a unique effective flood defense system to protect people and property from inland waterway floods caused by heavy rainfall, gales or rapid melting snow. This system has been developed in the Netherlands to provide optimal protection against extreme high water levels. The barrier systems have proved to be the best flood protection and has already been built and installed in several countries around the globe. In operational use globally since 1998, the SCFB™ is acclaimed as the world's most effective flood protection system. The success can be attributed to the simple, but ingenious concept of using the approaching floodwaters to automatically raise the barrier; effectively using the problem to create the solution. With an unblemished 100% track record the SCFB™ is a highly favorable preference when specifying optimal and cost effective but passive flood defence.

Key benefits

NO WARNING SYSTEM

The SCFB™ is not energy driven and operates without any human intervention and gives 24/7  a full 100% protection. Even when there is a power outage the SCFB™ will raises instantly though the rising water level.

No manpower 

 The SCFB™ request no manpower and for testing the barrier very few people are required.

No storage 

In resting position the SCFB™ is invisible and fully self-protected at the location in the ground. No storage elsewhere and transport is needed in case of testing or a flood situation.

Short closing time

Because of the short closing time the barrier will only comes up when there is a flood situation. No unnecessary falls deployment is needed. So the area remains accessible until the last moment.

Low operational cost

All applied elements represent the highest quality, with a unlimited time length. The recommended frequency for maintenance and testing of a flood barrier is once or twice a year. The SCFB™ can be connected to the main water supply ore filled by a pump. By filling up the pit the barrier is lifted automatically and ready for inspection so this is a one-man job.

The most reliable flood barrier 

Rapid onset flooding usually causes the greatest damage due to the lack of time to deploy the more traditional type of manually operated floodgates and "demountable" systems, typically stored off site, and requiring human intervention. The SCFB™ overcomes all the issues associated with these older- generation flood defences, and has the considerable advantage of not requiring any intervention during a flood warning, which would otherwise put lives at risk. The SCFB™ underwent in excess of 70 tests; these tests included static load, dynamic load, buoyancy force, sand and gravel tests, duration tests (35 days) extreme cold temperature tests, earthquakes tests, 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 system is made of very durable materials designed to last for 50 to 100 years and remains virtually maintenance free of many years.

The most economical flood barrier.

With a design life of 100 years, and requiring minimal maintenance, the SCFB™ is not only an extremely effective flood defence system, but it makes a strong economic case too. With zero operational costs the SCFB™ has none of the high on-going expenditure associated with manually operated systems. When not in use the barrier is protected underground and its seals are sheltered from the elements. The SCFB™ offers optimal protection against extreme high water levels, and a rigorous on-going R&D program ensures that the SCFB™ will remain the first choice for discerning clients seeking cost effective and superior flood defence solutions for decades to come.
