Concrete Repair in Metairie, LA

What Does Concrete Repair Cost in Metairie?

Concrete repair in Metairie runs $6 to $18 per square foot in 2026, depending on repair depth, subgrade condition, and access. A typical residential driveway repair covering 80 to 150 square feet lands between $1,200 and $3,600. Larger commercial flatwork repairs of 400 to 800 square feet run $4,500 to $12,000 once subgrade correction is included.

Four variables move that range in Metairie specifically. First, subgrade saturation: a water table at 2 to 3 feet requires active dewatering, adding $300 to $700 per mobilization. Second, spalling depth: surface delamination limited to the top half-inch resolves with a partial-depth repair and epoxy bonding agent, while full-depth deterioration requires slab removal and replacement. Third, base condition: organic silt that has compressed under the existing slab needs full excavation and 6 inches of compacted limestone before new concrete goes down. Fourth, access: slabs adjacent to structures or landscaping add hand-excavation time.

What Does Metairie Ground Demand from a Concrete Repair?

Soft alluvial clay and organic silt compress continuously under load, which means a repair that does not stabilize the subgrade will crack again as the ground beneath it settles. In Metairie, that failure mode makes subgrade treatment a standard line item, not an upgrade.

For partial-depth repairs addressing spalling or surface delamination, the existing slab is saw-cut to a minimum 2-inch depth, deteriorated material is removed, and the exposed face is primed with an epoxy bonding agent rated at 4,000 PSI or higher before the repair mortar is placed. This prevents delamination between the old and new concrete layers.

For repairs requiring subgrade access, the excavation goes to a minimum 12 inches below the finished slab surface. Saturated organic material is removed and replaced with 6 inches of compacted crushed limestone, verified at 95 percent standard Proctor density. The slab section is poured at 4 inches of 3,500 PSI concrete minimum, with 3/8-inch deformed rebar on 18-inch centers. Control joints are re-established at 10-foot intervals and sealed within 12 hours of the pour.

Crack injection with low-viscosity epoxy applies where the slab structure is sound but the crack has opened to 0.01 inches or wider. Epoxy injection under 40 to 60 PSI fills the crack from the bottom up and cures to a bond strength that matches or exceeds the parent concrete.

How Does a Concrete Repair Job Run in Metairie?

A standard Metairie concrete repair takes 2 to 4 days from mobilization to cured surface, with the subgrade work accounting for most of that time. Day one covers saw-cutting, demolition, and excavation. Saturated subgrade material that must be removed and dried before compaction can extend excavation to day two in wet conditions, which are common here given the water table depth. Limestone base placement and compaction to specification happen before any concrete is ordered. The pour itself typically takes a few hours. The repaired section is closed to foot traffic for 24 to 48 hours and to vehicle traffic for 7 days. Full cure reaches 28 days.

Recent Concrete Repair Project in Metairie

Driveway and apron repair, central Metairie, 120 square feet. The slab had settled 1.5 inches at the garage apron and showed full-depth cracking across two panels, a typical result of organic fill consolidating beneath a 1970s pour. Excavated to 14 inches, removed saturated silt, compacted 6 inches of crushed limestone to 95 percent density, and dewatered the excavation for 4 hours before placing base material. Poured two replacement panels at 4 inches of 3,500 PSI with 3/8-inch rebar on 18-inch centers, broom finish to match the existing surface. Epoxy crack injection addressed a 12-foot hairline crack in the adjacent panel that remained structurally sound. Three days total.

Questions Metairie Customers Ask About Concrete Repair

Can a settled slab in Metairie be lifted instead of replaced?

Mudjacking or polyurethane foam lifting works on slabs where the subgrade is stable but voids have formed underneath. In Metairie, the underlying clay and organic silt are often still consolidating, so lifting a slab without removing and replacing the failing subgrade material typically produces resettlement within 1 to 3 years. A probe of the base condition before choosing a repair method is the correct first step.

Do concrete repairs in Metairie require a Jefferson Parish permit?

Permit requirements depend on the scope of work. Surface patching and crack injection generally do not require a permit, but slab replacement that alters grade or drainage may trigger review. Confirm the threshold with the Jefferson Parish Department of Inspection and Code Enforcement before work begins.

How long does an epoxy crack injection repair last in Metairie?

An epoxy injection repair on a structurally stable slab lasts 10 to 20 years when the underlying subgrade is not actively settling. In Metairie, the repair life shortens if ongoing subsidence continues to stress the slab. Monitoring the repaired crack annually and addressing any new movement at the subgrade level is the most effective maintenance approach.
