Demolition, hauling, and disposal planning
Concrete Removal Cost Calculator
Answer first: turn slab dimensions into concrete weight, loose debris volume, haul loads, and an auditable removal cost broken into demolition, reinforcement, saw cutting, disposal, transport, fixed fees, and base repair.
10 ft x 10 ft x 4 in slab
about 2.5 short tons
At 150 lb/ft3 before soil, moisture, steel, mixed debris, or container tare is added.
One auditable total
7 visible cost lines
Breaking/loading, reinforcement, saw cuts, disposal, hauling, fixed fees, and base repair stay separate.
Slab dimensions to tons, haul loads, and removal cost
Keep every quantity and rate visible. Replace defaults with measured sections and written contractor, hauler, recycler, or disposal inputs before comparing bids.
Planning total
$1,258
$13 per ft2 from the entered scope and rates.
Concrete weight
2.5 short tons
5,000 lb / 2,268 kg before other debris and tare.
Loose debris screen
1.67 yd3
35% entered swell above solid slab volume.
Payload comparison
1 load
Comparison only; provider and legal load limits control.

What basic concrete demolition calculators hide
A national cost per square foot is not a quote. The useful calculation exposes the assumptions that change labor, payload, disposal acceptance, and the condition left for replacement work.
| Benchmark says | Replace with local input | Next check |
|---|---|---|
| One cost-per-square-foot number | Keep breaking/loading, reinforcement, access, saw cutting, hauling, disposal, fixed fees, and base repair as separate editable lines. | Ask each bidder to mark included, excluded, allowance, or unit-rate for every line. |
| Dumpster yards equal safe capacity | Show loose debris volume and weight separately, then compare weight only with a payload entered from the provider. | Confirm clean-concrete rules, container tare, fill line, included tons, overage, axle, route, and pickup limits. |
| Old slab out means site ready | Carry an optional base-repair line so soft soil, roots, failed gravel, grading, and compaction do not disappear. | Define the handoff condition before replacement pricing: debris removed, elevation checked, base repaired, and access restored. |
Concrete removal planning checklist
Confirm these items before comparing the planning total with a contractor, hauler, recycler, or disposal quote.
| Signal to check | What it means | Next step |
|---|---|---|
| Thickness and hidden sections | Thickness, thickened edges, footings, curbs, overlays, and separate slab sections were measured or explicitly allowed for. | Measure cores or exposed edges and price uncertain sections separately. |
| Utilities and slab type | Utility locating, post-tension risk, structural connections, drains, radiant heat, and hazardous coatings were reviewed. | Stop and use qualified locating, engineering, environmental, or demolition review where required. |
| Access and protection | Machine width, gate clearance, floor or driveway capacity, dust control, noise, neighbors, lawn protection, and hand-carry distance are defined. | Use the access multiplier only as a screen; replace it with a contractor method and price. |
| Haul and disposal | The provider confirms accepted material, payload, tare, included tons, overage, rejected loads, sorting, tickets, and final destination. | Do not choose a dumpster or truck from loose volume alone. |
| Final site condition | The quote says who removes steel, repairs base, backfills voids, compacts, cleans access routes, and prepares for the next trade. | Photograph and approve the removal handoff before replacement work starts. |

How do I calculate concrete removal cost?
Measure each slab section and thickness, calculate weight, then price breaking and loading, reinforcement, saw cutting, disposal, hauling, mobilization or permits, cleanup, and base repair separately. Replace every default with a local written rate before relying on the total.
How much does a 10x10 four-inch concrete slab weigh?
At 150 lb per cubic foot, a 10 ft by 10 ft slab at 4 inches thick weighs about 5,000 lb or 2.5 short tons. Soil, moisture, steel, coatings, mixed debris, equipment, and container tare are not included unless added elsewhere.
Does broken concrete take more dumpster space?
Usually yes. Broken pieces create voids, so loose debris can occupy more space than the solid slab. The calculator keeps a user-editable swell percentage, but weight and provider payload can still limit the load before container volume does.
Does rebar increase concrete removal cost?
Rebar or wire mesh can increase cutting, breaking, separation, sorting, and loading work. Select the reinforcement type and enter the premium quoted for the actual slab instead of assuming one universal markup.
Can this calculator choose a dumpster or approve a haul load?
No. It compares estimated material weight with a payload you enter. The provider must confirm container type, tare, allowed material, fill line, included tons, overage, truck and axle limits, route, placement, and pickup rules.
