How long has New Orleans Concrete Contractors been in business?

New Orleans Concrete Contractors has been pouring concrete across Greater New Orleans since 2016. The company serves residential and commercial customers across Jefferson, Orleans, St. Bernard, St. Tammany and St. Charles parishes, covering driveways, slabs, foundations, patios, parking lots and concrete repair.

Why do concrete slabs crack and settle so often in New Orleans?

Slabs crack and settle in New Orleans because the south shore sits on soft alluvial clay and organic silt with a water table 2 to 5 feet below grade. Clay expands when wet and shrinks when dry, pulling at the slab base. Proper base preparation, 4 to 6 inches of compacted limestone and a vapor barrier, reduces that movement significantly.

What concrete thickness do you pour for a residential driveway?

A residential driveway in this area gets 4 inches of 3500 PSI concrete over 4 to 6 inches of compacted crushed limestone base. Rebar runs at #3 on 18-inch centers for standard loads. The apron at the garage, where settlement is most common, gets a thickened edge and 6 inches of base.

How long before I can drive on a new concrete driveway?

Vehicle traffic is safe at 7 days after the pour. Foot traffic is safe at 24 to 48 hours. Full compressive strength at the design PSI is reached at 28 days. Driving on the slab before 7 days risks surface damage and edge cracking, particularly in warm weather when the cure is still active.

Do you work on both the south shore and the north shore?

New Orleans Concrete Contractors works on both shores. South shore and west bank jobs cover Jefferson, Orleans and St. Bernard parishes. North shore jobs cover Slidell, Mandeville and Covington in St. Tammany Parish. Specifications differ between the two because south shore clay subgrade and north shore sandy drainage flat present different preparation requirements.

What services does New Orleans Concrete Contractors provide?

Services include concrete driveways, patios, stamped and decorative concrete, slabs, repair, sidewalks, steps, resurfacing, leveling and lifting, removal and demolition, pool decks, retaining walls, garage floors, foundations, commercial flatwork, parking lots, ADA sidewalks and curbs, industrial flooring and drainage and detention work.

Key facts

Serving Greater New Orleans since 2016 across 4 parishes
Standard residential slab: 4 inches of 3500 PSI mix over 4 to 6 inches of compacted limestone base
South shore water table sits 2 to 5 feet below grade, requiring 6-mil poly vapor barrier on every slab
Control joints cut every 10 feet within 12 hours of the pour on all flatwork
Rebar specified at #3 on 18-inch centers for driveways and slabs subject to vehicle load

Why Does Local Ground Knowledge Decide the Outcome of a Concrete Pour?

Greater New Orleans sits on two distinct ground profiles, and each one demands a different approach before a single yard of concrete is placed.

What Does South Shore and West Bank Ground Require?

The south shore and west bank, covering Orleans, Jefferson and St. Bernard parishes, sit on soft alluvial clay and organic silt with a water table typically 2 to 5 feet below finished grade. Clay soil expands when saturated and contracts when dry, which is why slabs here settle, tip and crack at the edges. A slab poured directly over unprepared clay begins to move within a few years. The standard response is to excavate to stable subgrade, compact 4 to 6 inches of crushed limestone base at 95 percent proctor density, lay 6-mil polyethylene vapor barrier across the full footprint, and place 4-inch concrete at 3500 PSI minimum with #3 rebar on 18-inch centers. Driveways carrying vehicle loads get #4 rebar on 24-inch centers. Apron transitions at garage slabs, where settlement is most common, get 6 inches of base and a thickened edge.

What Does North Shore Ground Require?

Across Lake Pontchartrain in St. Tammany Parish, the ground shifts to sandy pine flat with genuine drainage. Slabs in Slidell, Mandeville and Covington do not settle the same way south shore slabs settle. The failure mode on the north shore is washout at slab edges when surface drainage is not controlled. Base depth on the north shore runs 4 inches of compacted gravel or limestone, and perimeter grading is detailed to carry water away from the slab rather than under it. Rebar and PSI specifications remain the same, because load and cure requirements do not change with drainage profile.

What Do River Parish Sites Require?

Destrehan and Luling in St. Charles Parish add levee-district review to the mix. Subgrade near the levee is often saturated clay at depth, and base preparation in those areas follows the same protocol as south shore work, with additional attention to surface drainage fall. Permit and setback requirements are confirmed with the relevant parish authority on each job before scope is finalized.

How Does the Work Proceed from First Call to Finished Slab?

A concrete job on this ground runs through five stages, and the time at each stage is predictable.

Estimate and Scope

A crew member visits the site, measures the footprint, assesses subgrade condition and reviews drainage fall. A site visit takes 20 to 30 minutes. A written estimate follows, broken down by demolition if needed, base preparation, concrete volume, reinforcement and finish. Nothing is committed until the scope is in writing.

Demolition and Subgrade Preparation

Existing concrete is removed by saw-cut and jackhammer, hauled off-site and disposed. Subgrade is excavated to the specified depth, inspected for soft spots, and compacted base material is placed in lifts and compacted to 95 percent proctor density. Subgrade preparation takes one day on most residential jobs and two days on larger commercial pads.

Pour and Finish

Concrete is ordered to the specified PSI, placed within 90 minutes of batching, consolidated with vibration and finished to the specified texture, whether broom, trowel, exposed aggregate or stamped. Control joints are cut or formed every 10 feet in both directions within 12 hours of placement to control crack location.

Cure and Handover

Curing compound is applied immediately after finishing. Foot traffic is safe at 24 to 48 hours. Vehicle traffic waits 7 days. Full compressive strength reaches design PSI at 28 days. The site is handed over clean, with joints sealed on request and grade confirmed to drain away from structures.

What Is Specified as Standard on Every Job?

Four specification items are standard on every residential flatwork pour in this service area.

Concrete mix: 3500 PSI minimum, 4-inch slump, fiber reinforcement added for crack resistance on patios and pool decks
Base: 4 to 6 inches of compacted crushed limestone, compacted to 95 percent proctor density
Reinforcement: #3 rebar on 18-inch centers for pedestrian slabs, #3 rebar on 18-inch centers or #4 on 24-inch centers for vehicle-load driveways
Joints: control joints every 10 feet, cut to one-quarter of slab depth within 12 hours of pour

Commercial work, foundations and industrial floors carry additional specifications confirmed during scope.
