Geophysics & Blast Response Mitigation at ISE

ISE has been working for close to two decades on innovative and unique engineering solutions to the problem of measurement and quantification of in-situ dynamic wave response analysis. We have analyzed ground-blasting response on everything from conventional bench blasting to underground nuclear testing.

Our service areas in this discipline include:

  • Passive and active monitoring using geophone or seismometer arrays.
  • Shear wave velocity testing, up-hole, down-hole seismic testing.
  • Structural response and ground coupling.
  • Sensitive site compliance testing and site selection due diligence.
  • Material and soil damping estimations including soil-structure transmissibility testing.
  • Construction and operational vibration isolation and avoidance.
  • Blast mitigation control using analytical and experimental methods.
  • Surface wave propagation analysis and damage avoidance.

Featured Video Clip (Concrete Fail)

ISE performing load testing of concrete test specimens to determine its axial compressive failure characteristics.

In this example, you can see quite dramatically how concrete fails under a compressive load. Once the ultimate stress is reached, the load carrying capacity of the material rapidly drops off producing the fracturing seen in the video.
