DGI completed Optical Televiewer (OTV) surveys to characterize shallow bedrock in Ontario. High resolution borehole imaging identified key structural features within migmatitic rocks and biotite gneisses. By collecting continuous, depth referenced borehole imagery, DGI delivered detailed structural characterization of the subsurface, including fracture orientation, foliation, and lithological contacts. The project improved confidence in geological interpretation and provided high quality structural data to support future geotechnical investigations and hydrogeological evaluations.
