Case Studies
Case Study – U.S.: Bridge Crack Monitoring in Pennsylvania
A transportation department in Pennsylvania installed wireless crack width monitors on a highway overpass. The system transmitted real-time data on crack movement to a central dashboard, enabling daily reviews and faster response times. Alerts helped avoid emergency shutdowns by flagging deteriorating conditions early.
Case Study – U.S.: Structural Crack Tracking in California Parking Garage
An engineering firm in California used Tilt Deflection Angle’s wireless crack monitoring systems during the seismic retrofitting of a multi-story parking garage. The sensors monitored concrete slab cracks throughout the retrofit, ensuring crack activity remained within acceptable thresholds and streamlining compliance reporting.
Case Study – Canada: Tunnel Infrastructure in British Columbia
In a major infrastructure project near Vancouver, crack width sensors were installed in an aging transit tunnel to track water-induced crack expansion. The data collected supported predictive maintenance and helped allocate resources efficiently during heavy rainfall months.
