Construction Products & Materials Supplier

Products

The quality of a finished project starts long before construction begins — it starts with the materials. Duininck mines, processes, and produces its own aggregate, asphalt, and ready-mix concrete, giving us direct control over what goes into every project we build. That's not standard in this industry. For our clients, it means tighter quality, fewer variables, and a partner who stands behind every layer of the work.

When we decided to improve our business' parking lot, there was only one choice in my mind...

Duininck! I’ve seen other jobs that were done by smaller, fly-by-night operations and I was not impressed. I knew if we were going to invest in improving our business’ facility, we wanted it done by a company we can rely on to do the job correctly, on-time, on budget and would be around in the future to stand behind their work. I was so impressed by Duininck’s estimate/bid price, I didn’t have to look any further. In addition, the job was finished a month before they originally thought it would be done!

Steve Nelson — Owner of Loftness Manufacturing

The Schwieter’s Chevrolet project in Willmar had a very aggressive schedule and Duininck was instrumental in the success of this project.

The owner took possession of the new facility the Monday after the Super Bowl in just under 6 months from start to finish. The Duininck team was excellent to work with and orchestrated the completion of a very difficult site in time to pave asphalt before freeze-up. Without Duininck’s horsepower, can-do attitude, and willingness to adjust on the fly, this project wouldn’t have been able to be completed until the following spring. We’ve been involved in construction projects in over 17 states. I would take Duininck any time on any project over any of the other site contractors we’ve worked with in the past. You guys rock!”
