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 concret
