Geotechnical Exploration and Sampling
DA Smith provides a full spectrum of geotechnical drilling services for site subsurface investigation. Our experienced personnel and adaptable equipment can meet the objectives of any project large or small.
Our fleet comprises both track-mounted and truck-mounted equipment and small rigs for accessing tight spaces such as beneath low-clearance structures or powerlines, inside buildings and basements, down narrow alleys, and in trenches. We have completed numerous projects for engineering and geological firms, constructors, government entities, mining companies, and property owners.
