Welcome to 3C Custom Commercial Concrete

Concrete Is Our Business

We don’t try to do it all. We specialize in concrete.

But when it comes to concrete, we do do it all.

We form it, we place it, we finish it. We excel at big, complex, structurally-critical commercial jobs. And we produce gorgeous residential driveways, firepits or custom-stamped patios – and everything in between.

We Have The Horsepower

3C is a large commercial concrete place and finish company in the Eugene/Springfield area. 3C is backed by a full crew with expertise in every level of commercial and residential concrete placement and finishing. We have structural crews, residential crews, custom concrete crews. However large or complex your job, 3C has you covered.

And, forget the delays of waiting for subs to come finish a portion of the job. One call to 3C, and you’re done. With all the expertise and power in-house, 3C controls the entire job and schedule. That means a more streamlined process with no bottlenecks.

We Have The Expertise

We’re new, but you already know us. Long time concrete finishers Sean Slater and Kevin Fonseca bring 35 combined years in working with concrete to 3C. What does 35 years look like? It looks like every concrete job you could conceive of. As Kevin says, “If it’s concrete, we do it.”

We're Always Available

Sure, we’re probably out there on a job site. But the phone is always answered by a real person, so you can quickly get a question answered, schedule an estimation, or just chat.
