Gregg understands that geotechnical testing requires us to meet exacting standards and perform our tasks with accuracy and without compromising results. The method and precision of obtaining data will influence decisions on future recommendations for use of a particular site. That is why Gregg utilizes state-of-the art equipment and instruments to collect geotechnical data. With senior technical leadership from Dr. Peter Robertson, Gregg has also aided in the design of specialty equipment, probes, and samplers to obtain data pertinent to geotechnical investigations.
