Concrete Driveways in Gretna, LA

What does a concrete driveway cost in Gretna?

Concrete driveway installation in Gretna runs $8 to $14 per square foot in 2026, including excavation, base material, concrete, reinforcement, and a broom finish. A 600 sq ft driveway lands between $4,800 and $8,400. A 900 sq ft driveway with a two-car apron runs $7,200 to $12,600.

Four things move the price on a Gretna job specifically. First, subgrade depth: lots where old fill sits over former backswamp clay sometimes require 8 to 10 inches of compacted limestone instead of the standard 6, adding $0.80 to $1.20 per square foot. Second, demolition of an existing slab runs $1.50 to $2.50 per square foot. Third, dewatering adds cost when the excavation hits standing water. Fourth, any section crossing the boundary between fill and native clay calls for #3 rebar on 18-inch centres rather than wire mesh, which adds material and labour.

What does Gretna's ground demand from a concrete driveway?

The dominant failure mode in Gretna is differential settlement where old fill meets native alluvial clay, and every spec decision on a driveway here flows from that fact.

Subgrade preparation starts with proof-rolling or probing the excavated base to locate soft zones. Any area that deflects under load gets over-excavated and replaced with compacted limestone in 3-inch lifts, each tested before the next lift goes down. The finished base is a minimum 6 inches of compacted limestone, rising to 8 inches where soft spots were found. Compaction must reach 95 percent of Standard Proctor density before concrete is placed.

The slab itself is 4 inches of 3500 PSI concrete. Wire mesh works on stable ground. On Gretna lots with mixed fill, #3 rebar on 18-inch centres holds the slab together if one panel settles relative to its neighbour. The apron, where the driveway meets the street and bears the sharpest load transitions, gets #3 rebar regardless of the rest of the lot condition.

Control joints are cut every 10 feet in both directions within 12 hours of the pour. The slab surface is pitched a minimum of 1/8 inch per foot away from the structure to carry rainwater off before it saturates the base.

How does the job run in Gretna?

A standard 600 sq ft driveway replacement in Gretna takes three to four days from demolition to final finish. Day one covers demolition and haul-off of the old slab. Day two covers excavation to the correct depth, subgrade testing, and base compaction. If soft zones require over-excavation and replacement, that work extends day two or adds a morning on day three. The pour and finish happen in a single day, followed by joint cutting the same day. Foot traffic is safe after 24 to 48 hours. Vehicle traffic waits seven days. Full cure is 28 days.

Recent project: driveway replacement in Gretna

Driveway replacement, Gretna

720 sq ft, two-car layout with an apron to a residential street. The original slab had dropped 1.5 inches at the midpoint where 1970s fill had consolidated into the native clay below. Removed to subgrade, probed the base, and found a 4-foot-wide soft zone running across the centre of the lot. Over-excavated that zone an additional 6 inches, brought it back with compacted limestone in lifts, then placed 6 inches of compacted base across the full footprint. Poured 4 inches of 3500 PSI with #3 rebar on 18-inch centres throughout, cut control joints at 10-foot spacing, broom finish. Four days total.

Questions Gretna homeowners ask about concrete driveways

Do I need rebar or is wire mesh enough for a Gretna driveway?

On lots in Gretna where subgrade probing shows consistent compacted fill, wire mesh at mid-slab is adequate. On any section where old fill meets native clay, or where a soft zone was found during prep, #3 rebar on 18-inch centres is the correct choice. The apron always gets rebar because load transitions there are the harshest.

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

Vehicle traffic is safe after seven days. Foot traffic is safe after 24 to 48 hours. Full compressive strength develops at 28 days. Parking heavy vehicles, trailers, or equipment before seven days risks surface marking and can crack a slab that has not yet reached design strength.

Will a concrete driveway settle in Gretna's soil?

A concrete driveway placed over a properly compacted and tested base will not settle under normal residential use. Settlement happens when soft zones are missed during subgrade prep, which is why compaction testing before the pour matters more in Gretna than in areas with stable sandy soil.
