Garage floor concrete in Juneau AK - a slab built to carry your vehicles
What goes into a new concrete garage floor in Juneau?
Juneau Concrete puts in garage floor concrete across Juneau as a thick slab with steel inside, made to take the weight of your vehicles. I come out to look at the garage and write the estimate myself, and on most garage jobs the bigger question turns out to be when to pour.
A garage floor goes in at the thick end of the usual range for home floors, with rebar or wire mesh inside, steel that holds the slab together under a heavy truck. If there's an old floor, we break it out and haul it off first. Then we cut control joints, shallow grooves that tell the concrete where to crack, because concrete cracks and it's better if we pick the spot.
On a garage floor the real question is often when to pour. A cold pour costs more, waiting for milder weather takes patience, and I'll lay both out so you can pick. Once the slab is in, we tell you when it can take your vehicle and keep heater exhaust away from it. Want color or a pattern on top? That's decorative concrete, priced on its own.
When a garage sits into a slope, the ground beside the driveway sometimes needs holding back, and our crew builds concrete retaining walls too. If you're also regrading around the garage, the engineering staff behind the City and Borough of Juneau's Permit Center offer public help on grading and drainage projects.
What the floor takes
- Breaking out and hauling the old slab
- Rebar or wire mesh through the slab
- A thicker slab for vehicle weight
- Control joints cut where cracks belong
- Covers against early freezing
- Heater exhaust kept off fresh concrete
What to weigh before pouring a garage floor
What moves the price
Size and thickness come first, then whether an old slab has to be broken out and hauled off, whether you want stain or color, and whether we're pouring in the cold.
What the schedule turns on
It turns on the weather and whether you'd pay for a cold pour or wait. Then the slab needs time to cure, hardening and gaining strength, before your car goes back in.
Ask what's in the mix
A mix with an air-entraining agent, which leaves tiny bubbles that give freezing water room, holds up better to freeze and thaw, and a drier mix shrinks less as it hardens.
Garage floor questions from Juneau
How much does a new concrete garage floor cost in Juneau?
A reinforced concrete slab in Juneau usually runs about $8 to $14 per square foot, and that doesn't include staining or stamping. If an old floor has to come out first, the demolition is added on top of that, so a tear-out pushes the number up. I come out, measure and give you a free written estimate, and our work is satisfaction guaranteed.
Can you pour concrete in cold weather in Juneau?
Yes, as long as the slab is protected, and the usual guidance counts it as cold work once the air is down to 40°F, or expected to drop below it, while the new concrete still needs shielding. A cold pour costs extra for insulating blankets, tarps, heaters and slower work, though it will likely keep the job on schedule. I'll weigh that against waiting for milder weather with you, and the Permit Center has a Cold Weather Concrete Policy you can ask them about.
How do I protect a new concrete slab from freezing?
Shield it from freezing for at least the first 24 hours, because concrete that freezes early can be ruined outright or left permanently weak. The guidance calls for that cover even in fall and spring in cold climates, since it's the surprise freeze that gets you. I'm on site for our pours and the covering is planned before we start, so ask any crew you're comparing how they'll cover the slab.
How long before I can park on a new concrete garage floor?
A new slab should be walkable within 48 hours, and to be safe you may want to wait a week before a vehicle or other heavy load goes on it. Concrete takes a month to fully cure, the slow hardening that gives it strength, so it keeps getting tougher after you start parking on it. We'll tell you when your floor is ready for your vehicle.
What causes a new garage floor to turn dusty?
One cause is exhaust from fuel-burning heaters or engines in the first 24 hours, because the carbon monoxide can leave a dusty surface on concrete that young. That's why we keep heater exhaust away from a fresh slab, and why you shouldn't idle a car or run a generator in the garage that first day.
Do I need a permit to pour a garage floor in Juneau?
It isn't settled for every job, so we check before we start. The city's engineering review list names site, grading, drainage and driveway work but not garage floor slabs, so when it's unclear we ask the Permit Center first. If a permit is needed, we file the application and book the inspections through our Civic Access account, the city's online system, and we're fully licensed and insured.
