Seismic Survey

Seismic Techniques are commonly used to determine site geology, stratigraphy, and rock quality. These techniques provide detailed information about subsurface layering and rock geo-mechanical properties using seismic acoustical waves. Reflection and Refraction are the most commonly used seismic techniques.

These methods determine geological structure and rock velocities by either refracting or reflecting waves off boundaries between rock units with different seismic velocities or impedance.


  • General geologic structure
  • Faults and other hazards
  • Landfill investigation
  • Overburden thickness
  • Rock rippability and quality
  • Water table depth
  • Bedrock depth
