Asphalt Services in Boulder
Parking Lot Paving
From retail centers along 28th Street to office parks near Flatiron, Boulder’s commercial properties see heavy daily traffic and tough winters. We handle full parking lot installations and replacements, including proper subgrade preparation, appropriate asphalt thickness for your traffic load, and ADA-compliant design. For lots that don’t need a full replacement, we also offer asphalt milling and overlays to restore the surface without the full cost of a new build.
Parking Lot Sealcoating
Boulder’s UV intensity and freeze-thaw cycles are hard on commercial pavement. Without regular protection, a parking lot that should last 25 years starts deteriorating at 15. We apply commercial-grade sealcoating and handle crack sealing before it goes down, so you’re not sealing over problems. Done right and done on schedule, it’s the most cost-effective maintenance decision you can make.
Asphalt Repair
Boulder’s freeze-thaw cycles turn small cracks into big problems fast. When it comes to asphalt repairs in Boulder, not every repair is the same. Surface deterioration and structural failure need to be treated differently. Skin patches where the base is still sound, full-depth repairs where the damage goes all the way through. Getting the diagnosis right is what separates a repair that holds from one that fails again in six months.
Parking Lot Striping
We handle new parking lot layouts and lot striping in Boulder, including ADA-compliant spaces, fire lanes, and directional markings. Restriping is also one of the fastest ways to get more usable capacity out of a lot you already have. We regularly pair striping with sealcoating for property managers who want both done in one visit. A freshly sealed and striped lot makes a bigger first impression than most property owners realize.
Driveway Paving
As a residential asphalt contractor in Boulder, we handle full driveway replacements, new extensions, and repairs to existing surfaces. We assess the base conditions first and build accordingly. Boulder driveways have specific challenges that a contractor without local experience won’t account for. You get a driveway built right the first time.
Driveway Sealcoating
Boulder gets intense UV exposure at elevation, and that sun breaks down asphalt faster than most homeowners expect. We handle driveway sealcoating in Boulder, including crack filling before the sealant goes down, so you’re protecting the surface, not just covering it up. Seal every 2 to 3 years, and your driveway lasts significantly longer than one that goes without.

What You Should Know About Paving in Boulder
Boulder’s soil conditions vary more than most people expect, sometimes within the same property. Near the foothills, you’re dealing with decomposed granite that drains fast but shifts. Closer to downtown, it’s clay that holds moisture and heaves when it freezes. Rock layers appear where you don’t expect them. A contractor who treats every job the same is setting you up for premature failure.
Permits are worth understanding before you start. Standard residential resurfacing typically doesn’t require one, but anything involving new impervious surface area triggers review. Boulder’s stormwater regulations are stricter than most Front Range communities, and commercial projects may require detention or water quality treatment depending on the scope. If you’re unsure what applies to your project, the City of Boulder Building Permits office is the right starting point. We help you navigate the process and pull the permits your project requires.

How Enright Diagnoses Pavement Failure in Boulder
Boulder pavement fails for six main reasons, and the fix only holds if you treat the right one. Asphalt that’s heaved from foothills clay needs a different repair than asphalt soaked by a Boulder Creek flood event. A contractor who patches both the same way will watch both fail within a season. We figure out what caused the damage before we tell you how to fix it.
Pierre Shale and Bentonite Heave
Root Cause: Much of Boulder sits on Pierre Shale and bentonite clay. Bentonite can swell up to 15 times its dry size when it gets wet. The ground under your pavement can lift and drop three to six inches every season, which tears the surface apart.
ENRIGHT SOLUTION
Site-specific subgrade preparation with adequate base depth and drainage grading, calibrated to the soil profile we find on your property.
Magnesium Chloride Brine Corrosion
Root Cause: CDOT sprays magnesium chloride brine on US-36, Foothills Parkway, and Broadway as the main de-icer. The brine sticks to tires and gets dragged onto your lot. It soaks deep into the asphalt binder and breaks it down over time.
ENRIGHT SOLUTION
Sealcoat every two to three years to block the brine and rebuild your surface protection. If your pavement already shows brine damage, we mill and overlay the affected areas, then finish with a full sealcoat.
Chinook Wind Surface Drying
Root Cause: Boulder gets strong Chinook winds off the foothills, sometimes over 80 mph. The hot, dry wind sucks moisture out of the asphalt binder and makes the surface brittle. Lots up against the foothills age the fastest because they take the hardest gusts.
ENRIGHT SOLUTION
We sealcoat wind-exposed lots more often, usually every two years, to lock moisture back into the surface. That keeps the binder flexible and protects your asphalt from drying out.
Boulder Creek Floodplain Saturation
Root Cause:Properties near Boulder Creek, Goose Creek, or Bear Creek sit on a floodplain with a high water table. Even without a flood, water stays close to the surface and keeps the sub-base wet. Wet base means soft base, and soft base means cracking.
ENRIGHT SOLUTION
We rebuild the base with extra drainage and a deeper aggregate layer to handle the high water table. For lots with active drainage issues, we add a grading plan to move water off the slab.
Steep Driveway Drainage Failure
Root Cause: Boulder driveways in the foothills often run on steep grades. Water races down the slope and washes out the base near the bottom. Once the base is gone, the asphalt above it sinks and cracks.
ENRIGHT SOLUTION
We add cross-slope drainage and grade the driveway so water runs off the side instead of down the middle. For washed-out sections, we rebuild the base before laying new asphalt.
Freeze-Thaw Alligator Cracking
Root Cause: Boulder crosses 32°F more than 100 times some winters. Water gets into unsealed cracks, freezes, expands about 9%, and slowly breaks the sub-base apart. The damage hides under the surface until it shows up as alligator cracking.
ENRIGHT SOLUTION
For small alligator-cracked sections, we do full-depth repair and rebuild the base underneath. For larger areas, we mill the surface and put down a fresh asphalt overlay.
