Why homeowners pick Tri-County
Slab removal is one thing; structures are another. We check permit requirements and asbestos risk on pre-1980 structures before demolition starts.
Hauling and disposal are included in the estimate. Concrete and rebar are taken to licensed C&D recycling facilities when possible.
The job is not finished until the site is clean. We leave it broom-swept for repour or final-graded for what comes next.
Details
Demolition is often the first real step toward a concrete project that lasts. If an old driveway, patio, slab, sidewalk, shed, garage, or retaining wall is already cracked, settled, or failing, covering it up rarely solves the problem. Tri-County Construction handles selective and full demolition across Delaware, including hauling and disposal, so the site is ready for repour or rebuild.
Most demolition work pairs directly with new concrete. The old slab comes out, the base is corrected, and the new pour starts from stable ground instead of a compromised surface. We also perform standalone demolition for site clearing, failing detached structures, old wall removal, and prep before another contractor takes over.
Structures can bring permit requirements, and pre-1980 structures need asbestos awareness before demolition. Concrete can sometimes be crushed on-site for fill when appropriate, reducing hauling costs. When disposal is needed, material goes to a licensed C&D facility and recyclable concrete and rebar are handled responsibly.
