Concrete Contractors in Covington, LA

What concrete services are available in Covington?

New Orleans Concrete Contractors handles the full range of residential and commercial flatwork in Covington. Residential work includes driveway installation and replacement, patio slabs, walkways, garage floors and aprons. Commercial work covers parking lots, loading areas, equipment pads and site flatwork. Every project starts with a subgrade evaluation, because in Covington the subgrade is the primary variable that controls how long the finished slab performs.

What do Covington's ground conditions mean for concrete?

Covington's sandy pine-flat soil drains surface water quickly, but that same permeability allows rainfall to migrate laterally beneath a slab and wash fine particles out from under the edges, leaving unsupported voids that cause edge cracking and corner breaks. This is the dominant failure mode in St. Tammany Parish and it is different from the settlement and heave common on the south shore's organic clay soils.

How does the sandy subgrade change subgrade preparation?

The sandy subgrade in Covington requires compaction to a minimum density before any base material is placed. Loose sand consolidates under load and during heavy rain events, so subgrade prep here involves mechanical compaction in 4-inch lifts rather than simple grading. A 4 to 6-inch layer of crushed limestone or recycled concrete base follows compaction, giving the slab a stable, drainable platform. Six-mil polyethylene sheeting is placed over the base to slow upward moisture migration and reduce bleed water at the surface during the pour.

What reinforcement and edge details matter most in Covington?

Because erosion concentrates at slab edges, Covington slabs use thickened edges of 6 to 8 inches at the perimeter rather than a uniform 4-inch thickness throughout. Number 3 rebar on 18-inch centres across the field ties the slab together if a void does develop beneath a panel. Positive drainage is graded at a minimum 1/8 inch per foot away from structures so runoff sheds clear of the slab edge rather than pooling along it. Where a slab borders a gravel shoulder or lawn edge, a formed concrete curb or concrete edging strip of 4 inches wide prevents lateral scour during the 4 to 6-inch rainfall events common in the Covington area.

What does concrete work cost in Covington?

Concrete work in Covington runs $8 to $13 per square foot for residential flatwork in 2026, depending on slab thickness, reinforcement, subgrade conditions and finish. A standard 600 sq ft driveway replacement lands between $4,800 and $7,800. A 400 sq ft backyard patio slab, broom-finished with basic grading, runs $3,200 to $5,200. A commercial equipment pad or parking bay at 4 inches over a prepared base runs $9 to $14 per square foot depending on load requirements and drainage tie-ins.

What moves the price on a Covington driveway or patio?

Four factors move the number on a Covington job. First, demolition and haul-off of an existing slab adds $1.50 to $2.50 per square foot. Second, subgrade repair when loose or washed-out sand is found below grade adds material and compaction time, typically $400 to $900 on a standard driveway. Third, decorative finishes such as exposed aggregate or stamped patterns add $3 to $6 per square foot over a standard broom finish. Fourth, drainage tie-ins or thickened-edge forming add $200 to $600 depending on the perimeter length involved.

What permits does concrete work require in St. Tammany Parish?

Flatwork permit requirements in St. Tammany Parish are set and administered by the St. Tammany Parish Department of Permits, and whether a specific project requires a permit depends on the scope of work. Projects that commonly trigger review include the addition of new impervious surface area, changes to site drainage patterns, work within a public right-of-way, and any construction in a designated flood zone. No specific thresholds, fees or setback distances are stated here because those figures are subject to change and must be confirmed against current parish records. Contact the St. Tammany Parish Department of Permits directly before work begins to confirm what approvals apply to your specific project and address.

Recent concrete projects in Covington

The two profiles below are representative of the work and the site conditions common in Covington. Customer names and addresses are omitted.

Driveway replacement, north Covington residential

Replacement of a 580 sq ft residential driveway where repeated heavy rain events had eroded the sand subgrade along both edges, leaving the outer 12 inches of each slab panel unsupported and cracked through. Removed the existing 4-inch slab to subgrade, mechanically compacted the sandy subgrade in two lifts, placed 5 inches of crushed limestone base, and formed thickened edges at 7 inches. Poured 4 inches of 3500 PSI concrete with number 3 rebar on 18-inch centres and cut control joints at 10-foot intervals. Broom finish. Four days from demolition to final joint sealing.

Backyard patio slab, south Covington residential

New 320 sq ft patio slab adjacent to a rear drainage swale. The challenge was a low spot at the back corner of the lot where runoff pooled against the planned slab edge during rain. Graded the subgrade to establish 1/4 inch per foot fall toward the swale before placing 4 inches of compacted gravel base. Formed a 4-inch concrete edging strip along the swale-facing edge to prevent lateral sand scour. Poured 4 inches of 3500 PSI concrete with wire mesh reinforcement and a brushed finish. Three days total including subgrade work.
