With roots solidly in the Midwest, Kolb Grading can travel to, and perform in, project environments across the continental United States. Serving in either a sub-contractor role or as a general contractor, Kolb Grading brings its commitment to safety, quality, timely project completion and being a good neighbor to any US neighborhood. In all cases, they are the local firm you want in your locale - working with local crewmembers, or bringing in a team - whatever it takes to bring about a successful, quality result.

The Indiana I-69 project is a project that involved a complex crew, multiple stages of work, challenges that were met, and wildlife considerations. Jeff Kolb commented, “We not only worked around the brown bat habitat, but we also worked around a bed of snails in a stream running underneath a bridge installation. We did extensive work in building embankments, excavating 10 million cubic yards of unclassified material, processing the materials to a 4 inch minus, and working with shale, sandstone, limestone and fat clays. We then refilled and built the embankments using the processed materials in conjunction with high strength geo-textiles for stabilization and erosion control.”
