Family owned and operated company since 1978.
In 1978, Sonny Kaltz founded Kaltz Excavating, a company that has developed its sterling reputation serving communities in Michigan for decades. To this day, we continue to be family-owned and family-operated.
To expand the scope of the services we offer and increase our ability to improve people’s quality of life, we acquired MUE Inc. in 1996, broadening our pool of top workers.
Acquiring Union Excavating in 2008 was another important milestone, and it further enhanced our ability to perform complex and varied projects. The acquisition is also further proof of our strong skills in management and collaboration.
Our facility in Pontiac, Mich., which we moved to in 2018, has marked an exciting and promising new chapter for our business. We continue to provide high-level services to numerous communities in the area.
