Why Kolb
More than a grading contractor.
A letter from our founder
Welcome to Kolb Grading
If you’re one of our clients, team or stakeholders, thank you for choosing Kolb Grading and supporting our business.
If you’re a new visitor, thank you for taking a few minutes to get to know us and learn more about who we are and what we do. When you leave our website, what I’d like you to take away is a sense of “Wow! I didn’t know you did all of that!”.
Kolb Grading has grown from a small business that provided earthmoving services to one that now provides a host of services in multiple markets for public, private and government entities. We continue to grow using technology to refine our processes, improve our quality, and provide outstanding customer experiences.
We stand behind our word and fulfill our commitments. We provide value engineering, timely completion of projects, and offer the benefit of our experience as a part of the planning process. We’re seasoned business people who understand budgets, the importance of communication, the value of long term relationships, and keeping a sense of humor.
Take a look through these pages and see how we can apply our services to your business. I’d be happy to discuss your next project with you to see if we’d be a good fit. Call me at our office in Weldon Spring, MO or send us a contact request by clicking here.
We’re proud of what our family team has created, and we’d like to be a part of your project.
I appreciate your time and consideration.
Sincerely,
Jeff Kolb
Vice President
Our Mission
To be the most trusted and comprehensive partner, driving projects with precision, innovation, and unmatched quality.
What we stand for
Core values
Kolb Grading has been family owned and operated since 1960, and the way we work has changed less than the equipment we work with. We show up prepared, we do what we said we would do, and we look after the people on the site and the partners who trusted us with it. Those habits are what let three generations of the Kolb family grow a local grading outfit into a heavy-civil contractor that mobilizes nationwide.
Traditional values
We stand behind our word and fulfill our commitments, the same way we have since 1960.
Safety always
Everyone goes home the way they came to work. No scope is worth a shortcut.
Family first
Three generations in, we run a national contractor with the values of a family business.
Forward thinking
Modern equipment and technology that sharpen our process and raise our quality.
Outstanding results
Value engineering, on-time completion, and experience brought to the planning table.
Long-term partnerships
Straight communication, fast pay, and relationships that outlast any single project.
