Under the Flatirons
Concrete contractor in Boulder, CO
Boulder is one of the towns we work most. Driveways, patios, walks and steps, from older houses near downtown to the postwar streets in south Boulder.
From Mapleton Hill to Table Mesa
Boulder sits at the foot of the Flatirons, with the University of Colorado and the Pearl Street Mall at its center. Many older homes sit on tight lots, so access and staging get planned at the walkthrough.
US 36 brings us in from the south. Martin Acres and Table Mesa were built after World War II, and Gunbarrel and North Boulder filled in later.

Older houses, tighter lots
Mapleton Hill, west of downtown, is one of the historic districts in Boulder, with houses going back to the late 1800s. Exterior changes in a historic district can need city review, so check with the city before you change anything visible from the street.
Martin Acres and Table Mesa are postwar ranches and split-levels. Driveways, front walks and steps from those decades are the usual jobs, and a plain broom finish with clean joints suits them.

Permits and the right of way
Work in the public right of way, such as a curb cut, a driveway approach or the city sidewalk, typically needs a city permit in Boulder. If your block has an association, get its sign-off before the pour, and bring both to the walkthrough.
Clay, frost and the first winter
Boulder County is known for expansive clay soils. Water makes the soil swell, which is why driveways and patios heave and crack. A prepared base and reinforcement hold the slab together, and control joints placed to spec decide where it cracks.
Our process stays simple: measured walkthrough, written scope and price, base prep, the pour, then a clean site. After the pour, hold off on deicing salt through the first winter and use sand for traction.

Good to know
Concrete in Boulder: questions
Do I need a permit for a new driveway approach in Boulder?
Work in the public right of way, like a curb cut or the city sidewalk, usually needs a city permit. Confirm with the city before the pour, and bring questions to the walkthrough.
When can I use deicer on a new concrete driveway?
Concrete contractors generally advise skipping deicing salt through the first winter, because new concrete is still drying out and the surface can scale. Sand gives you traction without the risk.
Do you pour stamped concrete in Boulder?
Yes: stamped and decorative patios, walkways, steps and driveway patterns. Boulder is one of the towns we work most, and we walk and measure the site before quoting.
