We've been at this a long time.
Since its founding in 1955, Tri-State Drilling, Inc. has been a family-run business. Today, in its second generation, Tri-State is recognized nationwide for its expertise in electrical transmission line foundations, but the company began as a municipal water well contractor and pump supplier. In those early days, the company had just four employees and co-owners: driller Wayne Riethmiller, driller's helper Ralph Eisele, mechanic Clarence Berthiaume, and pump salesman Bob Melcher.
In the 1960s, Tri-State's focus gradually shifted from drilling for water to drilling in order to remove water. We developed techniques for opening and maintaining wet holes, allowing us to install dewatering pumps. During that time, we also began installing drilled foundations for buildings.
In the 1970s, our utility work led to two other innovations. Our ability to maintain wet holes enabled us to install foundations in wet soils. Since utilities typically span great distances, Tri-State developed new techniques for quick and easy mobilization. This mobility brought us to the attention of power line contractors and by 1980, power line foundation work grew to over half of our total volume. In the late 1980s this expedited mobilization also made Tri-State attractive to the wireless industry, whose need for towers exploded in the mid-1990s.
Today, the lion's share of our work is for power line contractors, throughout the United States. Keep a lookout. You just might see our rigs somewhere, when you travel, or even in your own community. And although Tri-State has grown significantly in size and volume over the years, if you stop to say hello, you just might meet a friendly son or even a grandson of our original founders.
