Expert Concrete for Strong Foundations

At Flint Construction LLC, we believe good work starts with doing the basics right. We serve homeowners in Rapid City and across the Black Hills with honest communication, solid planning, and workmanship that is built to last. Most of our work is residential, and we also work with other contractors who trust us as a subcontractor. That kind of repeat business means a lot to us because it shows people know we do the job the right way.

Concrete is the core of what we do, and it makes up about 90% of our work. We know how important a strong base is, whether we are pouring a new driveway, slab, patio, sidewalk, garage floor, or foundation. We do not rush prep work or cut corners. We focus on proper site prep, correct compaction, slab thickness, rebar placement, vapor barriers, and the right concrete mix for the job. Those details matter if you want concrete that looks good, performs well, and holds up over time.

What We Do

• Concrete flatwork and slabs
• Driveways, patios, sidewalks, and garage floors
• Excavation and dirt work
• Site prep and grading
• Garage builds for residential properties

Why Homeowners Choose Us

We are a small team, and that helps us stay hands-on from start to finish. In most cases, the owner handles on-site estimates personally, so you get clear answers from someone with real field experience. For customers in northern areas like Sturgis and Spearfish, a senior teammate may handle the estimate, but the same standards still apply. We keep communication simple, straightforward, and honest so you know what to expect.

• High-quality workmanship with no shortcuts
• Clear, trustworthy communication
• Strong focus on foundations and site preparation
• Follow-ups with past clients and leads
• Service across Rapid City and a 100-mile radius in the Black Hills region

Built on Trust and Steady Growth

We are proud of the reputation we are building. Around 30% of our work comes from other contractor referrals, which says a lot about the trust we have earned in the industry. We did about $350,000 in revenue last year and are on track for around $550,000 this year. To us, that growth is a sign that customers value quality work, fair dealing, and a crew that shows up ready to get it done right.
