Ground penetrating radar (GPR) is an effective tool to rapidly image shallow bedrock under the right conditions. This project was conducted along a proposed pipeline alignment where geotechnical boring logs showed variable bedrock depth along the entirety of the alignment. The alignment consisted of a variety of ground … [Read more...]
Seismic Refraction
Pyramid Geophysical Services was contracted to perform seismic refraction survey along a proposed trail in North Carolina. The seismic refraction method consists of measuring (at known points along the surface of the ground) the travel times of compression waves (P-waves) generated by an impulsive energy source. In … [Read more...]
