Professional concrete installation follows a precise sequence of steps, from site evaluation and soil preparation through forming, pouring, finishing, and curing. Each phase plays a critical role in the final product’s strength and longevity. Knowing what to expect helps property owners feel confident throughout the project.
Whether you are planning a new patio, driveway, foundation, or walkway, understanding the concrete installation process takes much of the mystery out of the project. Many homeowners in New Orleans have questions about what happens between the day they sign a contract and the day they can walk on their new surface. At TurnKey Concrete Team, we believe informed clients are the happiest clients, so here is a clear look at how professional concrete installation works from start to finish.
Every successful concrete project begins with a thorough site evaluation. A professional crew visits the property to assess the existing conditions, including soil type, drainage patterns, grade elevation, underground utilities, and access for equipment and material delivery.
In New Orleans, this step is especially important because of our unique ground conditions. Much of the city sits on clay-heavy alluvial soil deposited by the Mississippi River over centuries. This soil expands when wet and contracts when dry, creating movement that can stress concrete if not accounted for during the planning phase. Low-lying areas in Gentilly, New Orleans East, and parts of the West Bank may also present high water table challenges that affect how the sub-base is prepared.
During this phase, measurements are taken, the project scope is confirmed, and any permits required by Orleans Parish or neighboring jurisdictions are identified. Our concrete installation team handles these details so you can focus on the finished result.
If an existing surface needs to be removed, demolition comes next. Old concrete, asphalt, pavers, or other materials are broken up and hauled away. Tree roots, debris, and vegetation are cleared from the project area.
For new construction on undeveloped ground, this step may involve clearing brush and topsoil down to stable, compactable material. In either case, the goal is to create a clean, level workspace where the new concrete will be placed.
This is one of the most important stages in the entire process, and it is where many shortcuts lead to problems later. The ground beneath a concrete slab must be properly graded to ensure water drains away from structures and does not pool beneath the concrete.
After grading, a layer of compactable aggregate, usually crushed limestone or gravel, is spread and compacted to create a stable, uniform sub-base. This layer serves two purposes: it provides a solid foundation for the slab and allows moisture to drain rather than sitting directly against the bottom of the concrete.
In areas with particularly soft or unstable soil, additional measures such as geotextile fabric, lime stabilization, or deeper aggregate layers may be necessary. The time and care invested in sub-base preparation directly correlates with how well the finished concrete performs over the decades.
Wooden or metal forms are set around the perimeter of the project area to define the shape and thickness of the concrete slab. Forms act as a mold, holding the wet concrete in place until it sets.
Precise forming is essential for clean edges, consistent thickness, and proper slope. The forms are staked securely and checked with levels and string lines to verify that the finished surface will drain correctly. For curved driveways, rounded patio edges, or custom shapes, flexible form materials are used to achieve smooth contours.
Steel reinforcement, typically rebar or welded wire mesh, is placed within the formed area before the concrete is poured. Reinforcement adds tensile strength to the slab, helping it resist cracking from ground movement, heavy loads, and temperature changes.
For residential flatwork like driveways and patios, welded wire mesh is common. For thicker slabs, structural applications, or areas with known soil instability, rebar grids provide greater strength. The reinforcement is positioned on chairs or supports so that it sits within the middle of the slab rather than resting on the ground. Proper placement ensures the steel does its job when the concrete is under stress. Projects that involve structural needs, such as concrete foundations, require more robust reinforcement planning.
On pour day, ready-mix concrete is delivered by truck and placed into the forms. The crew works quickly and methodically, distributing the concrete evenly throughout the formed area. Vibrators or tamping tools are used to consolidate the mix, removing air pockets that could weaken the finished slab.
Timing is critical during the pour, especially in New Orleans, where summer heat can cause concrete to set faster than expected. Experienced crews know how to adjust the mix design and work pace to account for ambient temperature and humidity. On extremely hot days, retarding admixtures may be added to slow the curing process and ensure adequate working time.
Once the concrete is placed and roughly leveled with a screed, the finishing process begins. A bull float is passed over the surface to smooth it and push aggregate below the surface. After the bleed water evaporates, hand troweling and edging refine the surface and create clean edges along the forms.
The final texture depends on the project’s requirements. A broom finish provides excellent slip resistance and is the most common choice for driveways and sidewalks. Smooth trowel finishes work well for interior floors and covered patios. Stamped and decorative finishes are applied at this stage for homeowners who want the look of brick, stone, or tile.
Control joints are cut or tooled into the fresh concrete to create predetermined weak points where the slab can crack in a controlled, straight line rather than randomly. These joints are typically spaced at intervals equal to about two to three times the slab thickness in feet.
In New Orleans, where soil movement is a constant reality, control joints are particularly important. They allow the slab sections to shift slightly without causing unsightly or structural cracks across the surface.
Curing is the chemical process through which concrete gains strength, and it requires moisture and time. After finishing, the surface is treated with a curing compound or covered with plastic sheeting or wet burlap to retain moisture. Proper curing dramatically improves the concrete’s final strength, surface hardness, and resistance to weathering.
Most concrete reaches about 70 percent of its design strength within seven days, but full curing takes approximately 28 days. During the first week, foot traffic should be avoided, and vehicles should stay off driveways for at least seven to ten days. Your installer will provide specific guidance based on the mix design and conditions.
Once the concrete has cured sufficiently, the forms are removed, and the site is cleaned up. Backfilling along the slab edges, final grading of adjacent areas, and debris removal complete the project. At this point, you can see the full scope of the finished work.

For a typical residential project like a driveway or patio, the active work usually takes two to five days. Curing adds additional time before the surface can handle regular use, generally seven to ten days for foot traffic and longer for vehicle loads.
Rain during or immediately after a pour can damage the surface and weaken the mix. Professional crews monitor weather forecasts carefully and will reschedule a pour if significant rain is expected. Light mist after initial setting is generally not a concern.
A standard 4,000 PSI mix is suitable for most residential flatwork in the area. For projects exposed to heavy loads or particularly challenging soil conditions, higher-strength mixes or fiber-reinforced concrete may be recommended.
You do not need to be present for every step, but it helps to be available on pour day and during the initial site evaluation. Your contractor should keep you informed of progress and any decisions that arise during the project.
Most contractors recommend waiting at least seven to ten days before driving passenger vehicles on a new driveway. Heavier vehicles, such as trucks or SUVs, should wait even longer, typically 14 to 28 days, depending on the slab thickness and mix design.
Minor hairline cracks are normal in concrete and usually do not affect structural integrity. If larger cracks develop, they may indicate sub-base issues or insufficient control joints. Contact your installer promptly for an evaluation and repair if needed.
