What goes into a driveway that lasts in Aurora
Most driveways we tear out around Aurora didn't fail because concrete is weak. They failed because of what's underneath. Break one out and you'll often find two inches of sandy fill sitting right on clay, no rebar, and control joints spaced so far apart the slab picked its own crack lines. The top looked fine for a few years. Then the clay swelled after a wet spring, the slab rocked, and the corners started to crumble.
A new driveway here has to deal with three things at once. Freeze-thaw cycles all winter long. Deicing salt dripping off every car that comes home. And expansive clay soil that moves when it gets wet. So we start with the base: dig out the soft stuff, put down compacted road base, and tie a rebar grid that keeps the slab in one piece if the ground shifts. Then we pour a 4,000 PSI air-entrained mix, which has tiny air bubbles that give freezing water somewhere to go instead of popping the surface off.
Typical pricing runs $8 to $12 per sq ft. A Standard 2-car driveway (about 600 sq ft) usually lands between $4,800 to $7,200. If your old driveway has to come out first, that's covered on our driveway replacement page.
Is your driveway problem urgent, or can it wait?
Not every crack means you need a new driveway. Here's how we sort it out when we walk a property.
Call soon if you see
- A slab edge or panel that sits higher than the one next to it, enough to catch a toe or a snow shovel
- Cracks you can slide a pencil into, or cracks that got wider since last winter
- Water running toward the garage or the foundation instead of the street
- Chunks breaking off along the edges where tires roll
- A section that rocks or thumps when you drive over it
Usually safe to watch
- Hairline cracks that have stayed the same width for a year or more
- Light surface wear or a little exposed sand on the top
- Small spots of discoloration from oil or rust
- A crack along a control joint, which is right where it was supposed to crack
Signs you need a new concrete driveway
Wide or spreading cracks
A crack that keeps opening lets water and salt under the slab. Every freeze pushes it a little wider. Once cracks run across most of the panels, patching just moves the problem around. We break it out and pour new over a rebuilt base. If the cracks are still narrow and stable, crack repair may buy you years first.
Flaking, pitting, and scaling
That rough, pockmarked surface near the garage door is usually salt damage. It's worst on driveways poured without enough entrained air or finished while the surface was wet. On a new pour we use air-entrained mix, don't overwork the surface, and seal it before its first winter. If the slab underneath is still solid, resurfacing can cover the damage for less.
Sunken or heaved panels
Clay soil swells when it's wet and shrinks when it dries out. That's how you get one panel sitting an inch low by the garage and another lifting near the street. Small drops can often be lifted with concrete leveling. Big ones, or panels that are also badly cracked, are usually better replaced.
Bad drainage and ponding
A driveway should fall away from the garage at about a quarter inch per foot. When it doesn't, water sits against the garage slab, freezes, and works its way into the joint. A new pour lets us fix the slope for good.
How we pour a concrete driveway
-
Walk the site and measure
We check the slope, the soil, where the water goes, and whether the apron touches the city sidewalk or curb. You get a written price before anything is scheduled.
-
Excavate and build the base
We dig out topsoil and soft fill, then lay and compact 4 to 6 inches of road base. On sites with heavy clay, we go deeper. This step decides how long the driveway lasts.
-
Forms and rebar
Forms set the shape and the slope. Rebar goes in on a grid, held up on chairs so it ends up in the middle of the slab, not lying in the dirt.
-
Pour, finish, and cut joints
We place a 4,000 PSI air-entrained mix at 4 to 5 inches thick, then strike it off, float it, and pull a broom across it for traction. Control joints go in every 8 to 10 feet so any cracking happens in a straight line where we want it.
-
Cure, then hand it back
We apply a curing compound right after finishing. You can walk on it the next day and drive a car on it after about 7 days. Heavy trucks should wait closer to a month.
What affects the price of a concrete driveway
Most Aurora driveways land between $8 to $12 per sq ft. Here's what moves a job up or down that range.
- Size and shape
Bigger slabs cost less per square foot. Curves, flares, and odd angles take more forming time.
- Site prep
A flat lot with decent soil is quick. Slopes, deep clay, or a lot of fill to dig out add labor and base material.
- Removing old concrete
Tear-out and haul-off run about $3 to $7 per sq ft. That cost is built into our replacement pricing.
- Finish type
Broom finish is the base price. Stamped concrete runs $14 to $22 per sq ft, and exposed aggregate falls in between.
- Access
If the truck can back right up to the forms, the job goes faster. Tight access means pumping or wheelbarrowing, and that adds time.
- Thickness and reinforcement
Four inches works for cars. If you park a work truck, a camper, or a trailer, we go to 5 or 6 inches with heavier steel.
Pouring a driveway through Aurora’s seasons
Winter
We can pour in winter on milder stretches, but the concrete needs blankets and can't freeze for its first few days. Most homeowners are better off getting on the spring schedule early.
Spring
Spring is when the calendar fills up. Wet clay can delay excavation after a big storm, so we check the subgrade before we pour.
Summer
Hot, dry, windy afternoons pull water out of fresh concrete too fast. We pour early in the morning, keep the mix cool, and get curing compound on right away.
Fall
Fall is a good time to pour, but get it done early. A new driveway should be sealed before the first snow and kept free of deicers through its first winter.
Aurora soil, salt, HOAs, and permits
Expansive clay soil
Much of Aurora sits on clay that swells when wet and shrinks when dry. A thin base on top of it is what makes driveways crack and heave. We dig out soft material, compact real road base, and use rebar so the slab moves as one piece. We also keep downspouts and sprinklers from dumping water at the slab edge.
Deicing salt
Salt and liquid deicers from the roads ride home on your tires and drip onto the driveway. They're hardest on concrete in its first year. Air-entrained mix and a penetrating sealer are the best protection. Shovel instead of salting that first winter.
HOA approval
Many Aurora neighborhoods have an HOA. Most don't care about a same-size gray replacement, but widening a driveway, adding a parking pad, or switching to stamped or colored concrete often needs architectural approval first. Get it in writing before your pour date. We can give you the specs your HOA will ask for.
City of Aurora permits
The city requires a permit for work in the public right-of-way. For most driveways, that's the apron, the curb cut, and any sidewalk you cross. Widening a curb cut is a right-of-way job. Requirements and fees change, so we confirm with City of Aurora Public Works for your address before we schedule.
Concrete Driveways FAQs
How much does a concrete driveway cost in Aurora?
Most new driveways run $8 to $12 per sq ft. A Standard 2-car driveway (about 600 sq ft) is typically $4,800 to $7,200. Removing the old driveway, stamped finishes, and extra thickness add to that. See our Aurora driveway cost guide for the full breakdown.
How thick should a driveway be in Colorado?
Four inches is the minimum for cars and SUVs. We go to 5 or 6 inches for heavy trucks, campers, or trailers, and thicken the edges where tires roll on and off.
How long before I can drive on a new driveway?
Walk on it the next day. Drive a car on it after about 7 days. Keep heavy trucks off for close to a month while the concrete gets to full strength.
Do I need rebar or is wire mesh enough?
On Aurora clay we use a rebar grid. Mesh often ends up pushed to the bottom of the slab during the pour, where it doesn't do much. Rebar on chairs stays in the middle of the slab, where it holds cracked sections together.
Should I seal a new concrete driveway?
Yes. Wait about 30 days for it to cure, then apply a penetrating sealer before the first winter. Reseal every 2 to 3 years after that. Sealing runs $1.50 to $3 per sq ft.
Will my new driveway crack?
Concrete shrinks as it cures, so some cracking is normal. Control joints make sure it cracks in straight lines at the joints instead of across the slab. A good base and rebar keep any cracks tight and level.
