Geotechnical services involve exploratory drilling combined with testing and instrumentation installation to determine sub-surface ground characteristics for infrastructure development purposes including, but not limited to; tailings storage feasibility or upgrades, pipeline alignment investigations, hydro-electric dam feasibility investigations or upgrades, road network evaluation, LNG facilities and construction/ foundation design for buildings. As of 2016 Geotech also has the ability to drill offshore with a barge and drill system. This method has been successful on multiple near shore (marine) LNG facility investigations.
Many mining, consulting, construction and utility companies, contract Geotech’s drilling services to complete subsurface investigations to evaluate their properties. Unlike exploration drilling, these geotechnical projects focus on the characteristics and structure of the subsurface material, rather than the value of the mineral composition.
Geotech was founded in 1996 with an emphasis on geotechnical specific programs, after identifying a need within British Columbia’s Ministry of Transportation division. Geotech facilitates investigations to obtain information required by clients including the drilling of multiple boreholes, completed with various in-situ tests and installations. These testing techniques include, but are not limited to; standard penetration tests, cone penetration tests, packer tests (pneumatic and hydraulic), shelby tubes, piston sampling, core orientation, vane shear (nilcon and standard), and hydro fracturing tests. Geotech also offers an array of instrumentation installation services, including, but not limited to; monitoring wells, vibrating wires, slope inclinometer casings, extensometers, de-watering pumps, and nested installations.
As of 2016 Gregg Drilling & Testing Canada, has become part of the Geotech Group of Companies and offers a full suite of competitive drilling and Cone Penetration Testing (CPT) services.
Since 1985, Gregg Drilling & Testing Inc. (Gregg), has been a leader and innovator in site investigation services. Gregg has been pushing cones for over 25 years and is currently one of the largest operators of CPT equipment. With multiple drill rigs and CPT trucks, Gregg has the experience, knowledge and systems in place to successfully complete large and high-risk projects for safety conscious clients.
Similar to Geotech’s exploration services, these geotechnical services have grown significantly and include projects in; the Canadian Arctic, Western Canada, USA, Chile, Greenland and Suriname.
Numerous major pipeline, mining, construction, consulting and utility companies have sought Geotech’s geotechnical services to complete projects, these clients include, but not limited to; AMEC, Golder Associates, BGC Engineering, Stantec Consulting, Worley Parsons, SNC- Lavalin Thurber Engineering Ltd., Anglo American, KGHM International (formerly Quadra FNX Mining), Teck Resources, Grande Cache Coal, Columbia Power Corporation and BC Hydro.
