Depth to Bedrock

ATV  Refraction


Several geophysical methods can be applied to locate and map the overburden and bedrock interface:

One or more methods can be applied depending upon the site and requirements. For example, a Resistivity imaging survey combined with Seismic Refraction can help resolve uncertainties if the bedrock interface is highly weathered.  GPR can be used to detect karst terrain if the overburden is not too clayey.  TDEM soundings are used in areas where local infrastructure make it unfeasible to lay out long seismic or resistivity cables.  Frequency domain Electromagnetic instruments such as the Geonics EM31 can map variations in the overburden to complement another method such as GPR.

DEPTH to BEDROCK information is required for:

  • Wind Farms
  • Solar Parks
  • Mine Infrastructure and Extraction Planning
  • Building Design
  • Buried Pipes & Utility Planning
  • Water Exploration
  • Contaminant Migration
  • Tailings and Settling Pond Design
  • Sand and Gravel Resource Estimation
  • ....and so on....
