Our Legacy

What started as hands-on grit has become an industry benchmark for safety and efficiency. We’ve built our reputation on reliability, reducing downtime and extending asset life across North America and beyond. Key Milestones:

  • 1985: Founded by John Lehman in Marietta, Ohio, as a small operation with limited resources but a laser-focused vision and a refusal to ever say no—solving some of the most challenging silo storage and blockage issues in the grain, food, and cement processing industries.
  • 1988-1989: Added dedicated supervisors like Phil Proctor, Mike Wagner, and Les Van Oster to handle more projects with personal service, while building a reputation on hard work and infallible reliability with a workforce of tough, determined individuals—many with farming backgrounds—who brought grit and problem-solving skills to every job.
  • Over 40 Years: Pioneered innovative cleaning and inspection technologies, developed proprietary equipment systems, and set industry benchmarks for safety, efficiency, and reliability—all while evolving from humble beginnings into a global leader with unchanged core values of excellence, integrity, safety, and relentless customer satisfaction.
