Solid granite? Not a problem.
Dewatering for utility contractors, whose work is spread along a line, let Tri-State develop a very mobile operation. To do this they purchased two pieces of equipment that again would change their focus business—the Watson truck mounted drill rig and the Barco boom truck. Along with the growing popularity of hydraulic rams, this equipment made it possible for crews to move to a new location and set up ready to drill faster than ever before. This capability allowed Tri-State to make roads into the power line construction industry.
From the regional base in the Midwest expansion to other large market proceeded at a rapid pace. Soon, Chicago, New England and the entire East Coast became as familiar to Tri-State crews as the plains of Minnesota. With the onset of cellular phones in the late ’70s and early ’80s Tri-State was mobilizing across the entire nation providing foundations for microwave towers as well as power lines.
As always, Tri-State is looking toward the future—purchasing the latest drilling equipment and pursuing drilling innovations. A recent addition to our stable of drill rigs is our 48” diameter Ingersol Rand Cluster Drill. It is capable of boring holes into solid granite at advance rates of 1’ to 2’ per hour. With this acquisition Tri-State can now say, "there is no rock we cannot drill."
So whether it is hard rock, unstable soils, high water table, or pier diameters to 18’—all are in a days work for Tri-State crews and equipment somewhere in the U.S. Whatever your project—The Rockies to the Appalachians, swampland, desert, or tidewater flats—Tri-State has:
- Environmentally sensitive experts for drilling in Flood Plains, Tidal Flats, and Marshlands.
- Management and employees that have more than 800 Years of Combined Drilling Experience.
