Drilling & Sampling

Triad owns and operates numerous drilling rigs. Our drilling fleet includes truck-mounted, track-mounted, skid-mounted and ATVmounted rigs. The fleet services our regional footprint as needed. The track-, ATV- and skid-mounted units can access the most difficult types of terrain. Our rigs provide support primarily for inhouse geotechnical engineering projects and Triad routinely provides subcontract drilling services for other consultants, private industry, and state, federal or municipal governments. Triad can provide drill crews who are OSHA and MSHA trained when required for a project.
