Geophysical Surveys

Geophysical surveys can provide a non-invasive and cost effective solution to locating and defining sub-surface features or anomalies.

The services we offer include:


  • Service utility locating.

  • Mine shaft locating.

  • Determining depth to bedrock.

  • Determining rock seismic velocities and rippability.

  • Void detection.

  • Peat thickness surveys.

  • Unexploded ordnance (UXO) surveys.

  • Landfill delineation.

  • Fault mapping.
  • Identifying relict foundations.
  • Locating groundwater table.
  • Locating unmarked graves.
  • Concrete thickness and reinforcement identification.

The geophysical methods we use include:


  • Ground Penetrating Radar (GPR).

  • Seismic Refraction.

  • Multi-channel Analysis of Surface Waves (MASW)

  • Continuous Surface Wave System (CSWS).

  • Electrical Resistivity Tomography (ERT).

  • Frequency-Domain Electromagnetic (EM) Induction.

  • Magnetometer Surveys.
