The founders of Hansje Brinker were looking for problems in 2008. “We had this great new technique, interferometry, to process radar images taken by satellite, but we were not sure how to apply it best,” said CEO Pieter Bas Leezenberg. The engineers didn’t have to search hard. “We got more then we wished for,” he added with a smile.
Hansje Brinker now uses the breakthrough technology to spot dynamic deformations in levees. “It monitors with millimeter accuracy along hundreds of miles of levees. So we can detect a problem really early, even before it becomes a problem,” Leezenberg says. “You see, the places where deformations appear are usually the same weak spots where cracks tend to develop later.”
According to Leezenberg, Hansje Brinker can be of great assistance to managers of waterworks to help keep people safe. ”Our images provide more information than you would get by inspecting on foot, and in less time. And we can go back in time to 1992,” he said.
Hansje Brinker’s largest project in the USA was scanning a dam for the Metropolitan Water District in California. The company’s technique is made for the American market, said Leezenberg. “Because this country is so big, it costs a lot of time and money to inspect structures in person. Infrastructure managers can use our QuickScan to identify risks after emergencies like earthquakes as well. This way they can support regular periodic inspection and maintenance without spending too much.”
Hansje Brinker already has plans to expand rapidly. “We can also use our QuickScan technique to monitor other major infrastructural works, like sewers, bridges, tunnels and railways. And the US has plenty of those.”
