VIBSIST-20, high resolution near surface seismic source

The VIBSIST-20 is a swept-impact, time-distributed seismic source. The seismic signals are generated by an electric hammer, which produces a rapid sequence of impacts according to a pre-programmed time function. The VIBSIST-20 is a non-destructive alternative that does not create environmental pollution such as chemicals and sound,. Legal risks frequently associated with using explosives are eliminated.

Key features

  • Portable and versatile
  • The VIBSIST-20 is portable, safe and versatile. It allows jobs to be done fast in very different conditions, from imaging ahead of tunnels to shear wave surveys on ground surface.
  • The VIBSIST-20 can also be used to generate and measure surface waves.

Applications

The VIBSIST-20 is intended for detailed P/S and surface waves surveys with a typical penetration range up to 250 m, in reflection mode. The fields of use include:

  • tunnel prediction
  • foundation engineering
  • roadbed and dam inspection
  • placer exploration
  • ground water exploration
  • ore delineation
  • research and education
