Serving Longmont for Over 30 Years
Enright has poured concrete in Longmont since 1989, and we know exactly what this ground does to a slab that wasn’t built for it. Longmont sits at roughly 4,979 feet at the foot of the foothills, with the St. Vrain Creek running through it. The soils here are loaded with the same expansive clay that runs under Boulder, the same Pierre Shale formation, and that clay is the single biggest reason concrete cracks early in this part of the Front Range.
We’ve worked on everything from driveways in the older neighborhoods around Old Town and Roosevelt Park to commercial lots along Ken Pratt Boulevard and the Highway 119 corridor. We know the way Longmont’s clay soils move with the seasons, the way the 30-inch frost depth shapes every footing, and the way runoff from the foothills puts pressure on drainage.
When you call us, you get a contractor who’s been on the Front Range for over 30 years, who builds to Longmont’s standards instead of cutting around them, and who pours residential and commercial concrete, ADA ramps, curb and gutter, and structural flatwork meant to last.
Why Longmont Property Owners Choose Enright
Family Owned, Personally Accountable: Enright is our last name. Every slab we pour in Longmont either builds or hurts that name. When your name is on the work, you make sure it’s worth it.
Since 1989 on the Front Range: Over 30 years watching how Longmont’s expansive clay soils, freeze-thaw cycles, and runoff from the foothills affect concrete over time. We pour for the conditions you actually live with.
BBB Accredited with an A+ Rating: Honest quotes, no bait and switch, and base prep that doesn’t get skipped to protect a margin. That’s how the rating gets earned over three decades.
Concrete Services in Longmont
Concrete Parking Lots
Commercial lots along Ken Pratt Boulevard, Main Street, and the Highway 119 corridor see steady traffic from retail, manufacturing, and delivery operations serving the broader Boulder-Longmont market. The Pierre Shale clay under Longmont moves under loaded slabs in ways that cheaper crews don’t account for. We pour to City Street Specifications, with the six-inch minimum non-reinforced concrete pavement on compacted subgrade that Longmont requires for structural sections, built to handle the loads and last.
Concrete Driveways
Longmont’s expansive clay sits on the same Pierre Shale formation that runs under Boulder, and it moves dramatically with moisture. Driveways in older neighborhoods near Roosevelt Park and newer builds out toward Prospect Ridge see the same swell-shrink cycle. We over-excavate where the clay needs it, compact the subbase to City spec, and reinforce strategically at the apron. The slab stays flat through Longmont’s freeze-thaw winters without heaving against the street edge.
Concrete Sidewalks
A cracked or uplifted sidewalk in Longmont’s older Old Town neighborhoods or along the St. Vrain Greenway becomes a trip hazard fast, and property owners carry the liability. We pour new sidewalks and replace failing sections to City spec, with proper width, slope for drainage, and detailing where walks cross driveways and curb ramps. Done correctly, the walk stays compliant and safe to use for decades.
Curbs & Gutters
Longmont sits at the foot of the foothills, and runoff from spring snowmelt and summer thunderstorms moves through town fast, much of it eventually into the St. Vrain. Failed curb and gutter lets water cut under your lot or driveway and undermine the base. We build curb and gutter to City standards, integrated with the storm system, so water gets carried away from your property instead of pooling against it.
Trash Pads & Equipment Pads
Longmont’s mix of commercial, restaurant, and light-industrial properties means dumpster and equipment pads carry serious load every week. Loaded compactors, frequent pickups, and pivot points where trucks turn all break down pads that weren’t built for the abuse. We pour reinforced trash pads at the thickness your actual operation requires, on properly compacted subgrade, with drainage designed to keep water moving away from the slab edge.
ADA Ramps
Accessible ramps on Longmont’s commercial properties, from Main Street storefronts to professional buildings out at Prospect Ridge, have to meet federal ADA spec. The 1:12 maximum slope, landing dimensions, ramp widths, and detectable warning panels at curb cuts all matter for compliance. We pour ADA ramps and curb ramps built to code from the start, so your property stays accessible and your Building Inspection passes without rework.
Concrete Permits & Regulations in Longmont, CO
Concrete work in Longmont has to follow City and federal rules, and getting them wrong is expensive. We handle the details so your project passes inspection and stays compliant.
Permits and right-of-way. Replacing an existing slab on the same footprint often doesn’t need a permit. But new work, added impervious surface, or anything in the public right-of-way (sidewalks, curbs, gutters, driveway aprons) usually does. The City of Longmont also requires a Construction Activity Permit for stormwater on projects above defined thresholds. We pull the paperwork through the City Building Inspection and build to Longmont standards.
ADA compliance. Public ramps, walkways, and parking spaces have to meet ADA rules for slope, width, landings, and detectable warning panels. Commercial work along Main Street, Ken Pratt Boulevard, and out at Prospect Ridge all gets held to this standard. We build to it from the start.
Stormwater and grading. Longmont’s Stormwater Construction Activity Permit is required for projects disturbing one or more acres or that are part of a Common Plan of Development. With the St. Vrain Creek running through town and significant runoff from the foothills, drainage matters here in a way it doesn’t on flatter ground. We design every pour to move water off the slab and off your property line.
We handle permitting as part of our service. We know what Longmont requires, including the stormwater rules that come with proximity to the St. Vrain. You focus on the results; we handle the paperwork.
