One of the largest concrete bridge in Poland – distributed crack detection
EpsilonRebars had been chosen for this project as the best solution dedicated to crack detection and estimation of their width changes. Four sensors were installed in the pylon’s horizontal beam, supporting the deck slab. In this case, a near-to- surface installation method was applied (grooves) to provide appropriate integration of EpsilonRebars with the existing concrete and to create natural protection against environmental impacts.

Benefits of using the DFOS monitoring system
Results of using the DFOS monitoring system
EpsilonRebars integrated within the bridge pylon allowed for detailed analysis of cracks’ patterns along the supporting beam. It was also possible to observe real-time changes in widths, despite being extremely small – see example data in the plot below. Analysis of such tiny events was possible only thanks to the appropriate mechanical properties of the Nerve-Sensors and their perfect bonding with the surrounding concrete.
