Concrete Contractors in Gretna, LA

What concrete services are available in Gretna?

We pour the full range of residential and commercial flatwork in Gretna and the surrounding Jefferson Parish area.

Residential concrete work in Gretna

Residential work covers driveway installation and replacement, front walkways, patio slabs, garage aprons, and shed or pool surrounds. A standard residential driveway is 4 inches of 3500 PSI concrete over a prepared base, with #3 rebar on 18-inch centres and control joints at 10-foot intervals. Exposed aggregate, broom, and brushed finishes are all available. Decorative stamped concrete is available for patios where drainage fall is confirmed before the pour.

Commercial flatwork in Gretna

Commercial work includes parking lot replacement, loading dock aprons, warehouse slabs, and ADA-compliant walkway pours. Commercial slabs start at 5 inches of 4000 PSI mix with #4 rebar on 12-inch centres. Thicker sections and higher PSI ratings are specified where load calculations require them.

What do Gretna's ground conditions mean for concrete work?

Gretna sits on alluvial clay and variable fill deposited over former backswamp, with a water table typically 2 to 4 feet below grade. This specific combination produces differential settlement: old fill compresses at a different rate than adjacent native clay, and the slab follows. The failure shows up first at driveway aprons, garage transitions, and any slab edge where fill depth changes abruptly.

Why differential settlement is the primary failure mode here

When a slab spans two zones of different bearing capacity, the zone over loose fill deflects under load while the zone over native clay stays stable. A 4-inch slab without reinforcement cracks at that boundary within 3 to 7 years under normal residential traffic. Rebar and fibre reinforcement slow the cracking but do not eliminate settlement once the subgrade moves. The only durable fix is correcting the subgrade before the pour.

How subgrade preparation changes in Gretna

On any Gretna slab over filled ground, subgrade compaction is tested with a nuclear density gauge or Proctor test to confirm 95% compaction before forming. Soft zones are excavated to a minimum of 8 inches below finish grade and replaced with compacted crushed limestone in 4-inch lifts. Where the water table is within 18 inches of the subgrade surface, a 6-mil polyethylene vapour barrier is laid under the slab to limit moisture wicking into the concrete. Drainage fall is set at a minimum 1/8 inch per foot away from structures so standing water does not saturate the base after the pour.

Slab thickness and reinforcement for Gretna soil

Residential driveways in Gretna are poured at 4 inches minimum, with 5 inches specified where the existing apron shows prior settlement or where site inspection reveals a shallow fill-to-native boundary. Commercial slabs start at 5 inches. Steel reinforcement is #3 rebar on 18-inch centres for residential work and #4 rebar on 12-inch centres for commercial. Synthetic fibre admixture at 1.5 pounds per cubic yard is added to all mixes as secondary crack control.

What does concrete work cost in Gretna in 2026?

Concrete pricing in Gretna follows Jefferson Parish labour and material rates, with subgrade repair being the variable that most frequently moves a west bank job above a simple square-footage estimate.

Three factors move the number specifically in Gretna. First, subgrade excavation and replacement adds $1.50 to $3.00 per square foot when soft fill zones require removal to 8 inches or deeper. Second, demolition of an existing slab runs $2 to $4 per square foot depending on slab thickness and rebar density. Third, tight access on narrower lots near central Gretna increases forming and finishing labour time. These ranges assume standard residential or light commercial loading. Heavier commercial specifications are quoted separately after a site review.

What permits and approvals are required in Jefferson Parish?

Flatwork permit requirements in Jefferson Parish are set and enforced by the Jefferson Parish Department of Inspection and Code Enforcement. Whether a specific concrete project requires a permit depends on factors including the amount of new impervious surface being added, changes to site drainage, work within a dedicated right-of-way, and whether the property falls within a mapped flood zone. Projects that increase runoff or alter drainage patterns are more likely to trigger review than simple like-for-like slab replacements, but the determination is made by the parish, not by the contractor.

Confirm the permit status of your specific project with Jefferson Parish Department of Inspection and Code Enforcement before work starts. Requirements can change, and the parish office holds the current thresholds, fees, and flood-zone maps for your address.

Recent projects in Gretna

Driveway replacement, central Gretna, 520 sq ft

The original slab had settled 3 inches at the garage apron where decades of fill had consolidated under traffic loading. Removal exposed a 14-inch deep zone of loose organic fill beginning 4 inches below grade. The soft material was excavated to stable bearing, replaced with two 4-inch lifts of compacted crushed limestone tested to 95% Proctor density, and topped with 6-mil poly before forming. The replacement slab was poured at 5 inches of 3500 PSI with #3 rebar on 18-inch centres and a brushed finish. The job ran four days including excavation, compaction testing, forming, pour, and finishing.

Backyard patio slab, west Gretna, 380 sq ft

The existing ground was saturated to within 10 inches of finish grade following a wet season, and the homeowner's previous attempt at a gravel base had washed toward the rear fence. The subgrade was regraded to establish a 1/4-inch-per-foot drainage fall toward a new perimeter channel, then compacted limestone was placed at 6 inches and tested before forming. A 4-inch slab of 3500 PSI concrete with synthetic fibre admixture at 1.5 pounds per cubic yard was poured with control joints at 8-foot intervals. Broom finish. The project took three days.

How do you get a concrete estimate in Gretna?

A free on-site estimate takes 30 to 45 minutes. The visit covers measuring the work area, walking the subgrade to identify soft zones or drainage problems, confirming access for the truck and pump if needed, and discussing finish and reinforcement options. A written line-item quote is provided within 24 hours of the visit. Call or submit the contact form to schedule.
