Geological Investigations

In situations where the geology or depth to bedrock is poorly constrained, geophysics can provide valuable information. Natural voids, sedimentary structures, or fractures and faults can cause significant problems if they remain undetected.

Electromagnetic mapping, electromagnetic profiling, electrical resistivity imaging, electrical resistivity sounding, seismic refraction and seismic reflection are all commonly employed in assessing near surface geology. Stratigraphy, depth to bedrock, presence of voids and hydrogeological assessments are all common applications of geophysical techniques.
