Gregg offers High Quality Geotechnical Site Investigation Solutions.

Gregg Drilling and Testing Inc., has been conducting geotechnical site investigations to assist clients in determining ground conditions for over three decades and is currently one of the largest operators of Cone Penetration Testing (CPT) equipment. In 2016, Gregg Drilling and Testing Canada Ltd., the Canadian division of Gregg Drilling and Testing Inc., became part of the Geotech Drilling Group of Companies after a long history of Gregg (headquartered in the US) and Geotech (headquartered in Canada) working together. The shared company experiences and capabilities were focused on delivering high quality site investigation projects in Canada and the USA. Now headquartered in Canada and Canadian owned, Gregg Drilling and Testing Canada Ltd., continues to deliver high quality in-situ testing and drilling services in support of the geotechnical engineering community throughout western and northern Canada.

Gregg works internally with their own in-house world-renowned experts in CPT technology, as well as externally with global leaders in CPT and other in-situ testing equipment to deliver best-in-class performance in the CPT market. Their successes and strengths in supporting the mining and energy sector revolves around their value based approach to obtaining high quality CPT, sCPTu, sampling and in-situ vane testing (among many other available tests) in marine environments, tailings ponds, dams, as well as in more traditional and routine land-based programs related to site development.

With multiple CPT platforms, mine site experience throughout Canada, and a highly experienced and motivated staff, Gregg Canada has the experience, knowledge and systems in place to successfully complete large and complex projects in the geotechnical investigation industry.
