NO CURRENT TOO STRONG, NO WATER TOO MURKY

When inspecting the below-surface structural integrity of bridges, conditions can often be less than ideal. Fast currents test the abilities of divers and murky waters hamper with their vision.

With VRT’s Multibeam Sonar and 3D Imaging Technology, underwater bridge inspections can be carried out faster, with more detail and, above all, safer than any traditional method. Our 3D images present decision makers with clear data on the condition of the structures and everything is done from the surface, so murky water and fast currents have no effect on results.

MAINTENANCE WITH PINPOINT ACCURACY

Maintaining a satisfactory condition of bridges is a legal requirement that ensures their safety for us all. A VRT underwater bridge inspection provides the most accurate way of fulfilling this requirement by pinpointing any possible needs for maintenance and repair work. The inspection of the structures and the sediment topography is considered to give a clear and complete overview of the overall condition.

With over 250 bridge inspections under their belt, our skilled inspectors are approved and qualified by the Finnish Transport Agency, FISE and Finnish Transport Agency’s guide for special structures 17 / 2013.

By using VRT's sonar technology, we can get a good overview of the targets, and we're not restricted by poor visibility in the water
