Concrete Driveways in Harvey, LA

What Does a Concrete Driveway Cost in Harvey?

A residential concrete driveway in Harvey runs $8 to $13 per square foot installed in 2026, or $7,200 to $11,700 for a typical 900 square foot two-car driveway. Four variables move that range the most.

• Demolition and haul-off of an existing slab adds $1.50 to $2.50 per square foot
• Subgrade repair on lots with settled or mixed fill adds $800 to $2,400 depending on depth
• Rebar grids cost more than wire mesh but are appropriate on known problem fill
• Decorative finishes such as exposed aggregate or stamped patterns add $3 to $6 per square foot over a standard broom finish

Permit requirements for driveways in Jefferson Parish are set by the Jefferson Parish Department of Inspection and Code Enforcement. Confirm current thresholds and fees with that office before work begins.

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

Harvey's alluvial clay and backswamp fill create the most common driveway failure in this area: differential settlement where old fill meets undisturbed native soil. The slab cracks at that transition because the two materials compress at different rates under vehicle load.

Preventing that failure starts below the slab, not at the pour.

Subgrade Depth and Compaction

Harvey driveway subgrades require excavation to a minimum of 8 inches below finish grade, with 6 inches of crushed limestone base compacted in two lifts of 3 inches each. Each lift is tested with a plate compactor to 95 percent standard Proctor density before the next lift goes down. On lots where old fill is mixed or soft, that base depth increases to 8 inches. Skipping compaction testing on Harvey fill is the single most common reason driveways settle within three to five years.

Slab Spec and Reinforcement

The slab is 4 inches of 3500 PSI concrete minimum. On apron sections and areas spanning a fill-to-native-soil boundary, 4.5 inches is the safer call. Reinforcement on Harvey driveways is #3 rebar on 18-inch centers rather than wire mesh alone, because rebar holds position during the pour and provides meaningful tensile resistance after settlement stress begins. Wire mesh collapses to the bottom of the form in wet conditions and contributes little once that happens.

Joint Layout and Drainage

Control joints are saw-cut every 8 to 10 feet in both directions, to one-quarter of the slab depth, within 12 hours of the pour. The driveway surface falls a minimum of 1 percent away from the structure to move water off the slab before it can pond and saturate the subgrade. With a water table 2 to 4 feet below grade, subgrade saturation accelerates settlement faster here than on the north shore.

How Does the Job Run in Harvey?

A standard Harvey driveway replacement runs four to six days from excavation to finishing, with one additional day if subgrade repair is needed. The sequence is: excavation and haul-off, subgrade grading and compaction with plate compactor, base material placement in two tested lifts, form setting, rebar placement, pour, surface finish, and control joint cutting. If groundwater intrudes during excavation, the crew dewatered with a submersible pump before compaction begins. Vehicle traffic stays off the slab for seven days minimum. Full structural cure is 28 days.

Recent Project in Harvey

Driveway replacement, Harvey

780 square feet. The original 1990s slab had dropped 1.5 inches at the garage apron where contractor fill from a 1990s addition met undisturbed clay. Full removal to subgrade, 8 inches of crushed limestone compacted in three lifts with Proctor testing at each, 4.5-inch slab at the apron transitioning to 4 inches across the field, 3500 PSI mix, #3 rebar on 18-inch centers, broom finish. Control joints cut at 9-foot intervals. Four days total, including one dewatering day after overnight rain raised the water table into the excavation.

Common Questions About Concrete Driveways in Harvey

Why do Harvey driveways crack faster than driveways elsewhere in the metro?

Harvey driveways crack faster because the variable fill beneath most lots settles unevenly, and most installations do not account for it at the subgrade level. A slab poured over inadequately compacted or mixed fill will crack within three to seven years regardless of concrete quality. Compaction testing at each base lift is the fix, not a thicker slab alone.

Is rebar required, or does wire mesh meet code in Jefferson Parish?

Wire mesh meets minimum code in Jefferson Parish for residential driveways, but rebar is the appropriate choice on Harvey lots with known fill or settlement history. Wire mesh loses its position in wet subgrade conditions and provides limited crack resistance once settlement stress develops. The cost difference between mesh and a #3 rebar grid on a 900 square foot driveway is roughly $400 to $700.

How long before I can park on a new concrete driveway in Harvey?

Passenger vehicles can use a new concrete driveway after seven days. Foot traffic is safe at 24 to 48 hours. Full structural cure, meaning the slab has reached its design strength, takes 28 days. Parking heavy trucks or equipment before 28 days risks surface marking and edge cracking on a fresh pour.
