Triad owns and operates numerous drilling rigs at various offices. Our drilling fleet includes truck-mounted, track-mounted, skid-mounted and ATV-mounted rigs. Drill rigs are available at all office locations as needed. The track-, ATV- and skid-mounted units can access even the most difficult types of terrain. Our rigs provide support primarily for in-house geotechnical engineering projects. In addition, Triad routinely provides subcontract drilling services for  other consultants, private industry, and state, federal or municipal governments. Support equipment includes water trucks, tanks, piping, pumps and portable grout mixer/pumps.  Triad can provide drill crews who are OSHA- and MSHA- trained when required for the project.
