Concrete Driveways in Kenner, LA

What Does a Concrete Driveway Cost in Kenner?

A concrete driveway replacement in Kenner runs $8 to $13 per square foot installed in 2026, putting a typical 600 square foot residential driveway between $4,800 and $7,800. A two-car apron with a longer run reaches $9,000 to $12,000 depending on demolition scope, subgrade repair, and finish choice.

Four variables move the number most in Kenner specifically. First, the existing slab often requires full demolition and haul-off because settled sections cannot be ground level without removal. Second, soft subgrade frequently needs 6 inches of compacted limestone rather than the 4 inches adequate on stable soil, adding material and compaction time. Third, lots with the water table above 3 feet may require dewatering before the base goes in. Fourth, a broom finish adds no cost, while an exposed aggregate or stamped finish adds $3 to $6 per square foot.

What Does Kenner's Ground Demand for a Concrete Driveway?

Kenner's soft alluvial clay compresses under load and loses bearing capacity when saturated, so the subgrade and slab spec both step up from regional minimums. The following is the standard we work to on Kenner driveways.

Excavation goes 10 to 12 inches below finished grade to make room for a 6-inch compacted limestone base and a 5-inch slab. A 4-inch slab on native clay alone will settle unevenly within a few years as the organics beneath compress. The limestone base is compacted in two lifts with a plate compactor, and compaction is confirmed before any concrete is placed.

Reinforcement is #4 rebar on 18-inch centers throughout, lapped 12 inches at intersections. Wire mesh alone does not provide sufficient tensile strength across settlement-prone soil. The concrete mix is 3500 PSI minimum. The apron at the street receives an extra #4 bar along each edge because the transition from slab to road surface concentrates stress where settlement is most likely to begin.

Control joints are tooled or saw-cut every 10 feet in both directions within 12 hours of the pour to direct cracking to predictable locations. Drainage fall is set at a minimum of 1/8 inch per foot away from the structure to move surface water off the slab before it finds its way through a joint and undermines the base.

How Does the Job Run in Kenner?

A standard Kenner driveway replacement runs 3 to 5 days from demolition to finishing, with one additional day if dewatering is required.

Day one covers demolition of the existing slab, haul-off, and excavation to depth. If the water table is sitting high, a sump pump runs overnight before base work begins. Day two places and compacts the limestone base in two lifts. Day three sets forms, ties rebar, and pours the slab. The concrete cures under burlap or curing compound, control joints are cut the same day, and the surface is broom-finished. The driveway is closed to foot traffic for 24 to 48 hours and to vehicle traffic for 7 days. Full design strength reaches 3500 PSI at 28 days.

Permits for driveway work in Kenner fall under Jefferson Parish Department of Inspection and Code Enforcement. Confirm current requirements and any apron replacement rules with that office before work begins.

Recent Driveway Project in Kenner

Driveway replacement, Kenner residential. The existing driveway was a 680 square foot slab poured in the early 1990s. Settlement had dropped the apron end 3 inches below the road surface, and a longitudinal crack ran the full length of the driver-side wheel track where the subgrade had lost support. Removed the full slab, excavated to 11 inches, dewatered for one day, then placed 6 inches of compacted limestone in two lifts. Poured a 5-inch 3500 PSI slab reinforced with #4 rebar on 18-inch centers, including double bars along both long edges. Broom finish, control joints at 10-foot intervals. Four days total.

Questions Kenner Homeowners Ask About Concrete Driveways

Why do concrete driveways in Kenner settle faster than in other areas?

Kenner sits on soft alluvial clay and organic silt that compresses gradually under the weight of a slab, especially when the water table rises and saturates the material beneath. A properly built driveway with a compacted limestone base and adequate slab thickness slows settlement significantly, but the ground condition is why the spec here is heavier than a national standard would suggest.

Is 4 inches of concrete thick enough for a Kenner driveway?

On Kenner's soft clay subgrade, a 5-inch slab is the practical minimum for a residential driveway. A 4-inch slab over unstable soil does not carry repeated vehicle loads without cracking. The additional inch adds modest material cost and meaningfully extends service life in these ground conditions.

Do I need a permit to replace a driveway in Kenner?

Driveway replacement in Kenner falls under Jefferson Parish jurisdiction, and permit requirements depend on the scope of work, particularly any changes to the apron at the street. Contact Jefferson Parish Department of Inspection and Code Enforcement directly to confirm whether a permit is required for your specific project before any demolition begins.
