Bridge Rehabilitation Project (New York)
In a rehabilitation initiative on a heavily trafficked bridge in New York, our crack width gauges enabled engineers to monitor expansion joints and deck surface cracks in real time. Integration with wireless transmitters provided remote access to readings, significantly reducing inspection costs and improving safety forecasting.
Seismic Zone Building Monitoring (California)
A structural consulting firm deployed our gauges in a high-rise building located in a seismic zone. The team used digital readings to develop a crack progression model post-earthquake. The system’s accuracy and alert function enabled rapid assessment and structural clearance.
Historic Structure in Ontario, Canada
To preserve the structural integrity of a 19th-century courthouse in Ontario, our non-invasive crack width gauges were used for long-term monitoring. The project required minimal interference with existing materials, and the system provided consistent data through seasonal changes, enabling conservation efforts with factual insight.
