Concrete Contractors in Broomfield, CO

Broomfield lies midway between Denver and Boulder along U.S. 36, at the north end of the area our concrete contractors cover. It incorporated as a city on June 6, 1961, and became a consolidated city and county on November 15, 2001, the 64th county in Colorado. Its growth is steady and long: 4,535 residents in 1960, 20,730 in 1980, 38,272 in 2000 and 74,112 in 2020. That gives Broomfield concrete from nearly every decade since the 1950s.

Old Broomfield and new Broomfield

The older parts of the city, built in the 1960s and 1970s, have driveways and walks that are past 50 years old. The neighborhoods added since 2000 have concrete that is mostly sound but often missing the extras homeowners want. So projects split roughly in two:

Older homes: full driveway replacement, front step rebuilding, and removal of patios that have sunk or cracked badly.

Newer homes: patio extensions, stamped entries, side walks to the backyard, and parking pads next to the driveway.

A cold, dry climate

Broomfield's climate is classed as cold semi-arid, with about 16 inches of precipitation a year, a January mean low of about 18°F and a USDA hardiness zone of 6a, with an average extreme minimum around −9°F. Dry air plus cold nights is a combination that tests exterior concrete. We use an air-entrained mix, keep the slab moist or sealed with a curing compound in the first days, and recommend a penetrating sealer once it has cured.

Wind and fast drying

On a windy day, dry air pulls moisture out of fresh concrete quickly. That can cause plastic shrinkage cracks, the fine surface cracks that show up within hours of a pour. We reduce the risk by pouring earlier in the day, using evaporation retarders when needed and starting curing right after finishing.

One government for permits

Because Broomfield is a consolidated city and county, the city council acts at the same time as the board of county commissioners. That simplifies things: one local government handles the rules for your project. We check the City and County of Broomfield's requirements for work at the curb, on the public sidewalk or for new slabs before scheduling.

Where the name and the rail lines came from

The Broomfield post office opened on September 26, 1884, and historians think the name comes from broomcorn, a sorghum grown in the area for broom-making. A narrow-gauge rail line arrived from Golden in 1873, two more railroads followed in 1881 and 1886, and the Denver–Boulder Turnpike opened in 1952. That long run as a farm town and then a commuter stop is why house ages vary so much from one neighborhood to the next. Before quoting, we look at the age and condition of the existing slab, not just its size.

A city that grew by annexation

During the 1990s Broomfield annexed land aggressively and spread into Adams, Jefferson and Weld counties as well as Boulder County. The 2020 census counted 31,298 housing units, and the count of households kept rising after that. Areas annexed at different times were built under different eras of practice, so two driveways a mile apart can have very different base and thickness under them. When we cut out an old slab, we measure what was there and set the new base to suit the soil we find.

What we pour in Broomfield

• Concrete driveways, replacement and widening
• Concrete patios, from small slabs to large entertaining spaces
• Stamped concrete patios, walks and front entries
• Sidewalks and steps
• Garage and shed slabs
• Concrete repair and replacement

Base preparation

The base under a slab matters more than most people think. We remove topsoil and soft material, add gravel and compact it in layers with a plate compactor. A firm, even base helps concrete resist settling and frost heave. On lots with clay soils that swell when wet, a deeper gravel base and good drainage reduce movement. Skipping this step is one of the most common reasons newer concrete fails early.
