Family-Owned, Built on 30+ Years of Experience
Hamman Developing & Grading was built with a clear purpose: deliver disciplined, high-capacity excavation company services that support Indiana’s commercial and industrial growth. From data center and solar farm sites to lake homes, municipal infrastructure and civil site development, everything we do is grounded in precision, safety, and accountability.
Hamman is family-owned. Our owner took over the business from his father and brings more than 30 years of his own experience, building on the years his father put in before him. We’ve always operated on a simple principle — execute correctly the first time, protect the schedule, and safeguard the integrity of every project we touch.
What Drives Our Work
We approach every job through three core values. Precision keeps our grading accurate and our sites compliant. Safety ensures every crew member and stakeholder is protected on what is one of construction’s most risk-sensitive phases. Accountability means developers, engineers, and project managers always know where their project stands.
As an excavation company in Indiana built for commercial scale, we combine experienced operators, heavy-duty equipment, and structured site management to deliver results that hold up through every phase that follows.
Serving Northern Indiana
We serve North Webster and all of Kosciusko County, plus Fort Wayne, Auburn, Kendallville, Huntington, Elkhart, Mishawaka and Plymouth. Each community brings its own soil conditions, regulatory environment, and project demands. Our regional experience means we adapt quickly and perform consistently — wherever the work takes us.
Lay the Groundwork for Success
When your commercial or industrial project is on the line, the right excavation partner matters. Downtime, compliance failures, and rework are expensive. Precision, safety, and reliability aren’t optional.
Hamman Developing & Grading delivers excavation services in Indiana designed to protect your investment and support long-term growth. If you’re planning a commercial build, utility installation, or large-scale earthwork project, now is the time to partner with a team built for results.
