Concrete Contractors in Marrero, LA

What concrete services are available in Marrero?

New Orleans Concrete Contractors handles the full range of residential and commercial flatwork in Marrero. That covers driveway installation and replacement, patios, walkways, garage slabs, shed pads, parking lots and commercial aprons. Decorative finishes including broom, exposed aggregate and stamped concrete are available on any of those surfaces.

Every service uses the same subgrade process because the ground in Marrero does not change between a patio job and a parking lot job. The clay and fill conditions under the surface are the constant that governs every pour in this city.

What do Marrero ground conditions mean for a concrete pour?

Marrero sits on former backswamp that was progressively filled over the past century, which means any given lot may have native alluvial clay under one section and old variable fill under another. When a slab bridges both materials, the fill compresses at a different rate than the clay. That differential settlement is the specific mechanism behind the cracked driveways and tilted slabs common in this part of Jefferson Parish.

The water table runs 2 to 4 feet below grade across most of Marrero. At that depth, moisture wicks upward through the subgrade continuously. A slab poured directly over uncompacted or saturated material will lose support from beneath as that material shifts with seasonal moisture cycles.

How is the subgrade handled on Marrero jobs?

Subgrade compaction testing is a required step on every pour in Marrero, not an optional upgrade. After stripping the existing surface, the crew probes and evaluates the material below. Soft or inconsistent zones are over-excavated and replaced with clean limestone base compacted in 3-inch lifts to 95 percent Proctor density. The final base depth is 4 inches minimum for residential flatwork and 6 inches for driveways and commercial surfaces that carry vehicle loads.

A 6-mil polyethylene vapor barrier is placed over the compacted base before any pour in Marrero. The barrier reduces moisture transmission from the saturated subgrade into the slab. Slabs are reinforced with #3 rebar on 18-inch centres for residential work and #4 rebar on 12-inch centres for commercial or heavy-load applications. Slab thickness is 4 inches for patios and walkways and 5 inches for driveways and garage slabs where the high water table increases long-term settlement risk.

What does concrete work cost in Marrero?

Concrete flatwork in Marrero runs $8 to $13 per square foot for standard residential surfaces in 2026, covering demolition of the existing slab where needed, compacted limestone base, a 3500 PSI mix with rebar, and a broom finish. A 500 square foot driveway replacement runs $4,000 to $6,500. A 300 square foot patio runs $2,400 to $3,900.

Three things move the number specifically in Marrero. First, subgrade repair: when the crew finds soft or inconsistent fill, over-excavation and replacement adds $1.50 to $3.00 per square foot. Second, demolition depth: slabs that have settled and require breaking at multiple levels take longer to remove and haul. Third, drainage corrections: if the existing slab directed water toward the structure, regrading to correct the fall adds labour and sometimes additional base material.

Decorative finishes such as stamped or exposed aggregate add $3 to $6 per square foot over standard broom finish pricing.

What permits and approvals does Marrero concrete work require?

Flatwork permit requirements in Jefferson Parish vary by project scope, and the authority for Marrero is the Jefferson Parish Department of Inspection and Code Enforcement. In general, work that adds new impervious surface, changes site drainage, encroaches on a right-of-way, or falls within a designated flood zone is more likely to require a permit or additional review before work can start.

Replacing an existing driveway in kind may fall below the review threshold, while adding a new apron to the street or expanding a parking area is more likely to trigger a drainage review. Flood-zone status affects requirements in parts of Jefferson Parish, and a property's elevation certificate may be relevant to the scope of approvals needed.

Confirm your specific project requirements with the Jefferson Parish Department of Inspection and Code Enforcement before work begins. Threshold figures and fees are set by the parish and change; confirm current values directly with the office.

Recent concrete projects in Marrero

Driveway replacement, Marrero residential

640 square feet. The original 1970s slab had dropped 3 inches at the garage apron where old fill had consolidated under vehicle load. The crew removed the full slab to subgrade, revealing a soft zone approximately 8 feet wide at the transition between the fill and native clay. That zone was over-excavated an additional 6 inches, backfilled with compacted limestone in 3-inch lifts, and tested to 95 percent Proctor before forming. The finished slab is 5 inches of 3500 PSI over 6-mil poly with #3 rebar on 18-inch centres. Broom finish. Four days including subgrade repair.

Rear patio and walkway, Marrero residential

320 square feet of patio and 48 linear feet of 4-foot-wide walkway. The rear yard had no positive drainage fall, and standing water after rain had saturated the top 6 inches of subgrade. The crew stripped and removed the saturated material, replaced it with 4 inches of compacted limestone, and formed the slab with a 1.5 percent cross slope toward the yard edge to establish positive drainage away from the structure. Slab is 4 inches of 3500 PSI over 6-mil poly. Broom finish on the walkway, light exposed aggregate on the patio field. Three days.

How do you get a concrete estimate in Marrero?

Estimates in Marrero are free and happen on site, not over the phone. A crew member walks the area, checks the existing surface and subgrade conditions where visible, measures the work area, and notes any drainage or access issues. The visit takes 20 to 30 minutes. A written estimate follows within one business day, itemising demolition, subgrade work, concrete spec, reinforcement and finish separately so the scope is clear before anything is signed.
