Built on Integrity. Grounded in Craftsmanship.
At NorthStar Concrete Works, we believe concrete is more than just the foundation beneath your feet — it’s the backbone of every great project. Based in Alexandria, MN, we’re a full-service concrete contractor proudly serving residential, commercial, and agricultural clients throughout the area.
From driveways and patios to barn pads and decorative finishes, every job we take on is guided by the same promise: to do it right, not just fast.
Who We Are
NorthStar Concrete Works is a family-owned and operated business led by husband-and-wife team Nick and Catharine Hammje. What started as a passion for hard work and quality results has grown into a trusted name throughout the community.
When you hire NorthStar, you’re not dealing with a revolving door of subcontractors — you’re working directly with the owners who care deeply about every pour, every edge, and every finish. Our hands-on approach ensures that every detail meets the highest standards of strength, precision, and aesthetics.
