How thick should a concrete driveway be?

For passenger cars and pickups, 4 inches. For light trucks, 5 to 6 inches, and thicker again for heavy trucks, according to the Virginia Ready Mixed Concrete Association. Say what will park on it before you get a quote.

Does a driveway need rebar or wire mesh?

Reinforcement helps hold cracks tight and the slab together if the ground moves, but it doesn't stop concrete from cracking. The joints decide where cracks form, and the base decides whether the slab stays level. Ask what reinforcement is included and why.

Can my old driveway be poured over?

Usually it's better to take it out. New concrete poured over a cracked, sunken slab tends to crack in the same places, and it raises the surface against the garage and the street. If the old slab is level and sound, ask whether an overlay (a thin new layer on top) makes sense.

Do I need a permit to widen my driveway in Huntsville?

If the widening reaches the street, yes. The City of Huntsville's Driveway Curb Cut Permit covers building, altering or replacing any driveway approach or curb, and only the owner, an authorized representative or a contractor can apply. Work on your own lot is a separate question; ask the City's Inspection Department.

Replace or repair a concrete driveway?

Not every tired driveway needs to come out. Replacing it usually makes sense when:

Cracks are wide, keep growing, or have edges at different heights.
Panels have sunk, tilted or broken into pieces.
Water runs toward the garage or the house instead of away from it.
The surface is flaking or crumbling over a large area.

If one or two panels have simply sunk, lifting them back into line can cost much less than a new driveway.

What a lasting concrete driveway needs

A compacted, even base. The ground is graded, soft spots are dug out and replaced, and the base is compacted. Around Huntsville that matters: the Geological Survey of Alabama describes much of Madison County as limestone and chert weathered into clayey soils.
The right thickness. 4 inches for passenger cars and pickups; 5 to 6 inches for light trucks; more for heavy trucks (Virginia Ready Mixed Concrete Association).
Control joints in the right places. The National Ready Mixed Concrete Association (NRMCA) puts joints no more than 24 to 36 times the slab's thickness apart. On a 4-inch slab, that is about every 10 feet. Each joint is cut at least a quarter of the way through the slab, and never less than 1 inch deep.
Drainage. The slab is sloped so rain runs toward the street or the yard, not the garage.
A finish for traffic and weather. A broom finish gives grip when it's wet. Exposed aggregate and stamped borders are options.
Proper curing. NRMCA calls for curing to continue for at least 3 to 7 days, usually by keeping the surface moist or covered.

When you can drive on a new concrete driveway

Don't drive on new concrete for at least seven days, advise both the Virginia and Iowa ready-mixed concrete associations, and the Virginia association says to keep heavy trucks off for at least six months. Through the first winter, skip de-icing salt: NRMCA advises against de-icing chemicals in a slab's first winter. Sand gives grip without the damage.

Driveway widening, extensions and parking pads

A side strip for an extra car, a turnaround or a pad for a trailer can be poured next to the existing driveway, with a joint between old and new. New concrete starts out lighter than old concrete and darkens over time.

City permit for the end of the driveway at the street

The part of the driveway that meets the street (the approach) is regulated by the City. Huntsville's Driveway Curb Cut Permit is the permit "to construct, reconstruct, alter, remove or replace any driveway approach, or any curb, guttering, or sidewalk." Its points:

It's issued by the City's Traffic Engineering Office, 2100 Clinton Ave W, (256) 427-6850.
Only the property owner, an authorized representative or a contractor can apply. The application includes a sketch of the work.
The City's page doesn't list a fee; ask Traffic Engineering when you apply.
In one of Huntsville's historic districts, new drives also need a Certificate of Appropriateness from the Historic Preservation Commission before a building permit is issued. The application costs $15.

Concrete or asphalt driveway?

In its concrete-versus-asphalt comparison table (June 2025), HomeGuide lists concrete at $6 to $14 or more per square foot, lasting 30 to 40 years, and asphalt at $5 to $12 or more, lasting 15 to 30 years. Angi (August 2026) gives concrete 30 to 50 years. Asphalt also needs resealing every few years. If you're weighing the two, ask for both prices in writing for the same area.

Driveway price ranges

HomeGuide's main driveway guide (June 2025) puts a new concrete driveway at about $6 to $15 per square foot, plus about $3 to $8 per square foot to remove old concrete. See concrete driveway cost in Huntsville for local estimates and a calculator.
