Concrete driveway building in Juneau AK - a slab built for freezing weather
What goes into building a concrete driveway in Juneau?
Juneau Concrete builds concrete driveways in Juneau from the ground up. Most of the work is the part you won't see once it's done. We dig out soft ground, pack a firm base and grade it so water runs off, then plan the pour around freezing weather.
Most calls start with an old drive that's cracked, sunk at one end or holding water by the garage. That trouble usually starts under the slab, so on the estimate visit I look at the subgrade, the ground the slab sits on, and where the water runs before we talk about the finish. I'll also ask whether the drive comes off a city street or a state highway, since that decides who handles the permit.
Weather data for Juneau show an average of 53 freeze-thaw cycles a year, so the mix matters as much as the base. One concrete additive maker advises an air-entraining mix, which holds tiny air bubbles that give freezing water room to push, and it's fair to ask whether any quote includes one. The mix we quote is meant for freezing weather.
Layout counts here too. A drive steeper than 10% or longer than 150 feet goes to the Fire Department for an emergency access review and may need a turnaround, and drives usually can't come closer than 6 feet to the side property line. The city's driveway page covers both. If a concrete patio is on your list as well, I can look at both on the same visit.

- Grading so water runs away from the garage
- A mix meant for freezing weather
- Cut joints so cracks land in line
- Protecting the young slab from cold
What to weigh before building a concrete driveway
What sets the cost
Size, base work and finish set most of it. If money's tight, skip the stamped pattern before you skimp on the base, because nobody fixes a base without tearing out the slab.
What sets the timing
Weather and curing, the wait while the slab hardens before use, set the schedule. Near or below 40°F fresh concrete needs protection, so we plan cold-season pours around the forecast.
Slab design for your load
Tell us what you'll park on it. Everyday cars set the usual slab, but bigger loads or weak ground call for a different design, often with rebar, steel bars that hold cracks tight.
Juneau driveway questions
Do I need a permit to build a driveway in Juneau?
Yes, a driveway from a City and Borough of Juneau street onto your lot needs a permit, and the city's General Engineering Division reviews it. A drive off a state highway, street or road goes to the state Department of Transportation instead. When a city permit is needed, we file the application and book the inspections through our Civic Access account, and if it isn't clear, we ask the CBJ Permit Center before we start. We're fully licensed and insured.
How much does a concrete driveway cost in Juneau?
A concrete driveway in Juneau usually costs about $7 to $14 per square foot, not counting tearing out an old driveway. Reinforced concrete runs more per square foot than plain, and demolition adds to the total. I come out, look the job over and give you a written estimate, so you know what's in the price before anything gets poured.
Can concrete be poured in cold weather in Juneau?
Yes, concrete poured in cold weather still gets strong and durable when it's mixed, placed and protected properly. The protection is the part people skip, so we plan it into every cold-season pour, and I'm on site for the pour myself.
How long before I can drive on a new concrete driveway?
Longer than it looks, because concrete keeps gaining strength well after you can walk on it, and color or surface hardness won't tell you when it can take heavy loads. We start curing right after finishing and keep vehicles off the edges and corners early on. Ask us when it's ready for your car and when it's ready for anything heavier, and we'll tell you for your slab.
What causes a concrete driveway to crack and sink?
Usually a poor base, meaning ground that was raked smooth instead of dug out and packed, so it settles and takes the slab with it. Spots over a culvert, trench or fresh fill need their own fix, not just thicker concrete. We also cut control joints, shallow grooves that give the slab a straight place to crack, before the slab picks its own spot. A nice finish on a bad base is just a good-looking crack waiting its turn.
How do I protect a new concrete driveway in its first winter?
Use sand for traction instead of deicing salt that first winter. One concrete additive maker advises this because deicers speed up scaling, the flaking and chipping of the top surface. A broom finish, light grooves brushed across the surface, also gives tires and boots some grip on ice.
