Concrete Removal: How Old Slabs Are Hauled Away

Removing old concrete involves more than just breaking it apart. From site preparation and equipment selection to debris hauling and responsible disposal, the process requires planning, heavy machinery, and experienced operators to get the job done safely and efficiently.

When Does Concrete Need to Be Removed?

Old concrete slabs eventually reach a point where patching and resurfacing no longer make sense. A driveway with deep structural cracks, a patio that has settled unevenly, a sidewalk lifted by tree roots, or a commercial floor that has outlived its useful life all become candidates for full removal. Sometimes the concrete itself is fine, but a property owner needs it gone to make way for new construction or a different layout.

At TurnKey Concrete Team, we handle concrete removal projects throughout Greater New Orleans, and we have refined our process to be as clean, fast, and cost-effective as possible.

Evaluating the Slab

Before any equipment rolls onto the site, we evaluate the concrete to understand what we are working with. Key factors include the slab’s thickness, whether it contains reinforcement like rebar or wire mesh, its total area, and what lies beneath it. Older residential slabs might be a straightforward four-inch unreinforced pour, while commercial slabs can be eight inches thick or more with heavy reinforcement.

We also identify any utilities that run under or through the concrete, including water lines, gas pipes, sewer connections, and electrical conduit. Utility locating is a non-negotiable first step that prevents costly accidents and service interruptions.

Preparing the Work Area

Preparation involves clearing the area around the concrete, setting up access routes for equipment and trucks, and protecting anything that should not be disturbed. Adjacent landscaping, fences, and neighboring concrete surfaces get covered or barricaded as needed. For residential projects, we discuss truck and equipment staging with the homeowner to minimize impact on the yard and driveway.

Breaking the Concrete

The breaking phase uses different equipment depending on the size and thickness of the slab. For most residential driveways, patios, and sidewalks, a skid steer equipped with a hydraulic breaker attachment is the primary tool. The operator systematically works across the slab, fracturing the concrete into pieces that can be scooped up with a bucket attachment.

Larger and thicker slabs may require an excavator-mounted hydraulic breaker, which delivers more force and can handle heavily reinforced concrete that a skid steer cannot manage. Handheld jackhammers come into play for edges, corners, and areas where large equipment cannot reach safely. Around foundation walls and tight spaces between buildings, manual breaking gives operators the precision needed to remove concrete without damaging adjacent structures.

In many cases, concrete saws are used first to cut clean boundary lines. This prevents cracks from running into concrete that will remain in place, giving the finished project a neat, professional edge. Our article on efficient concrete removal techniques covers additional methods we use to keep projects moving.

Separating Reinforcement

If the slab contains rebar or wire mesh, the steel needs to be separated from the concrete debris before hauling. Workers use cutting torches, reciprocating saws, or bolt cutters to free the reinforcement from broken concrete sections. The steel is set aside for recycling, and the clean concrete is loaded separately. Keeping materials sorted from the start saves money at the disposal facility and supports responsible waste management.

Loading and Hauling

Broken concrete is loaded into dump trucks or roll-off containers using a skid steer, excavator, or wheel loader. A typical single-car driveway removal generates roughly five to eight cubic yards of material, which usually fits in one standard dump truck load. Larger projects like a commercial parking lot can fill dozens of loads.

Hauling logistics matter more than most people realize. The distance to the disposal or recycling facility, traffic conditions, truck weight limits on local roads, and the number of available trucks all affect how quickly debris can be cleared from the site. Experienced contractors plan their hauling strategy in advance to avoid bottlenecks.

Recycling and Disposal

Concrete is one of the most commonly recycled construction materials. At recycling facilities, old concrete is run through crushers that break it down into gravel-sized aggregate called recycled concrete aggregate (RCA). This material is used as road base, pipe bedding, fill material, and even as partial replacement for virgin aggregate in new concrete mixes. Recycling is typically less expensive than landfill disposal, benefiting both the environment and the project budget.

Final Cleanup and Site Prep

After hauling is complete, small fragments and loose material are cleaned up. The exposed subgrade is inspected for soft spots, drainage problems, or unexpected conditions like old tree roots or buried debris. If new concrete will be poured, the subgrade is graded to the correct elevation and compacted to provide a stable base. Proper compaction is essential to prevent settling of the new slab.

How Long Does Removal Take?

Most residential slab removals are completed in one to two days, including breaking, loading, hauling, and basic cleanup. Larger residential projects or those with limited access may stretch to three days. Commercial removal projects vary widely based on volume and site complexity.

Weather is always a factor in the New Orleans area. Rain makes the ground soft, which can limit heavy equipment operation and create muddy conditions. Scheduling removal work during a dry stretch produces better results and a cleaner site. For guidance on seasonal planning, check our article on the best time for concrete projects in Louisiana.

What Does Concrete Removal Cost?

Removal costs depend on several variables: the total area and thickness of the slab, whether reinforcement is present, equipment access, hauling distance, and disposal fees. Reinforced concrete takes more time and equipment wear to break and separate, so it costs more per square foot than plain concrete. Sites with limited access, where material must be moved with compact equipment, also carry higher labor costs.

When removal is part of a larger project that includes demolition of structures above or around the concrete, coordinating both phases together can reduce overall costs. Our demolition services are often paired with removal to streamline the work.

If the concrete you are removing was once in good condition, our article on concrete resurfacing options explains alternatives to full removal when the slab is still structurally sound.

For projects in the Greater New Orleans area, our TurnKey Concrete Team removal service handles the complete process. We also address common maintenance questions in our guide to prolonging concrete life, which can help you decide whether removal is truly necessary.

Frequently Asked Questions

Can I remove a concrete slab myself?

Small, thin slabs (under four inches thick and unreinforced) can sometimes be broken up with a rented jackhammer and hauled away in a trailer. Anything thicker, reinforced, or larger than about 100 square feet becomes very difficult without professional equipment. The cost of renting tools often approaches the cost of hiring a contractor.

How heavy is a concrete slab?

Concrete weighs approximately 150 pounds per cubic foot. A standard four-inch-thick slab covering 100 square feet weighs roughly 5,000 pounds. That is a significant amount of material to break, lift, load, and transport, which is why heavy equipment is essential for most removal projects.

What happens to the dirt underneath after removal?

The exposed soil is graded and evaluated. If new concrete is planned, the subgrade is compacted to proper specifications. If the area will be landscaped, topsoil may need to be added since the soil beneath a slab is often compacted and nutrient-poor.

Do I need to be home during concrete removal?

You do not need to be present for the entire process, but we recommend being available at the start so the crew can confirm the scope, discuss any last-minute details, and address access or protection concerns. After that, the crew can work independently.

Is concrete removal loud?

Yes, breaking concrete with hydraulic breakers and jackhammers produces substantial noise. Work is performed during standard daytime hours to respect neighbors and comply with local regulations. We notify adjacent properties when possible and keep the noisy phases as brief as practical.

Can removed concrete be reused on my property?

In some cases, yes. Broken concrete can be used as fill material, drainage rock, or a base layer for new construction on the same property. However, the pieces need to be an appropriate size and free of contaminants. Your contractor can advise whether on-site reuse makes sense for your specific project.
