The company’s story began when Ray Schraufnagel and Roy Lemke started a plumbing business together in 1950. As the Milwaukee Metropolitan area grew, so did Super Excavators. The firm expanded into larger, tougher, deeper open cut utility projects as cities grew, earning an excellent reputation for quality work along the way. During the 1970s and 1980s, Super Excavators hand mined and used tunnel boring machines (TBM) for small tunnels. When Bob Schraufnagel took the reins, he continued building the business, expanding beyond Wisconsin borders to Albuquerque, New Mexico. In the early 1990s, Super Excavators landed its first large project in Kenosha, Wisconsin, as Jeff Weakly built the company’s tunneling business. Super Excavators became a larger presence in the tunneling world, job by job, building a stellar reputation beyond Wisconsin state lines. Today, Super Excavators has built tunnels across the entire United States from San Francisco to Delaware and Miami to Chicago. We specialize in large TBM projects up to 23 feet in diameter, microtunnel projects, pilot tube microtunnels, and bored casings. Super Excavators Inc. is a union employer, and signatory to multiple unions nationwide. OUR VISION We specialize in complex tunneling projects across the U.S. and Canada.
