Robertson’s Remarks

Gregg is pleased to provide a reference library for industry knowledge, created by Dr. Peter Robertson.

Dr. Robertson is the Technical Advisor for Gregg Drilling and Testing Canada Ltd. In this role, he assists clients in the interpretation of geotechnical data and provides oversight to Gregg with regard to business management.

Dr. Robertson is an acknowledged authority on in‐situ testing techniques and particularly on the electric cone penetration and seismic cone penetration tests. He has authored over 100 technical papers on the cone, dilatometer, and pressure meter and published a manual on the use and interpretation of cone penetration testing. He has conducted many seminars on in‐situ testing methods throughout the world. Recent research has been directed towards the use of the Seismic Cone Penetration Test for Evaluating Liquefaction Potential and the Estimation of Foundation Settlements in Sand.

Dr. Robertson’s website was created to provide information about Cone Penetration Testing (CPT) and liquefaction to practicing engineers and geologists. He has included all of his technical papers for reference as well as Robertson’s Remarks and other informal information about cone penetration testing.
