ESG offers custom seismic equipment for monitoring underground caverns, tunnels, and structures such as dams, bridges, railway tracks and buildings.

Our instrumentation and services have become the industry standard for many unique environments that require careful monitoring of the surrounding rockmass.

The flexibility of our systems allow for sensor installation from the surface or from the cavern or tunnel interiors, and our unique product line offers permanent systems for long-term installations, or portable rapid-deploy systems for short-term risk assessment. We also provide integrated instrumentation monitoring solutions that automatically collect other types of geotechnical data from measuring ground movement, hydraulic pressure and stress/strain. ESG’s iAccelerograph and iSeismograph are examples of portable Paladin™ based monitoring systems that are ideal for seismic monitoring of civil/geotechnical applications.

Our systems are fully automated and web-enabled which means they can be accessed through the internet from virtually any location in the world.  The detected seismicity can be time-scaled and mapped in 3D, providing operators and engineers with visualization capabilities of seismically active areas within the structure, including where and when they occurred and at what strength (magnitude).
