Equipment Rate Calc

Concrete Removal Calculator

Estimate concrete removal pricing from slab area, thickness, production rate, machine cost, hauling, disposal, mobilization, and margin. Results update automatically as inputs change.

Inputs

Job assumptions

Measure the slab footprint in square feet; split irregular areas into documented sections and add them once.

Measure more than one exposed edge or test location; do not assume the slab is uniformly thick.

Use recycler data, scale tickets, or a project-specific density. The 2.0 default is an editable planning example.

Use completed square feet per productive hour from comparable thickness, reinforcement, access, attachment, and cleanup conditions.

Enter the recycler or disposal facility's current charge per accepted ton and verify contamination requirements.

Enter the full internal cost of trucks, drivers, fuel, route time, waiting, and unloading for the planned loads.

Enter the one-time equipment delivery, pickup, setup, and site-arrival cost not included elsewhere.

Operating cost

Enter the loaded machine-and-operator cost per productive hour, including wear and overhead allocated to that hour.

Profit & protection

Margin is profit divided by the final selling price, not a markup on cost.

How this calculator works

Cubic yards = area × thickness in feet ÷ 27. Estimated tons = cubic yards × entered concrete density. Quote = machine time + dump fees + hauling + mobilization, then apply margin.

Read the methodology and editorial policy

Turn slab dimensions into weight and cost

Use this calculator for patio, sidewalk, driveway, and small slab removal where thickness, hauling, dump fees, and machine wear can quickly change the price.

This tool is best for pricing compact-equipment concrete tear-out jobs. It connects measured area and thickness to an editable density, disposal weight, production time, hauling, and margin. Review reinforcement, thicker-than-expected slab, limited access, base contamination, saw cutting, and cleanup expectations before relying on the result.

Worked example

A 600 sq ft slab at 4 inches thick is about 7.41 cubic yards. At an entered density of 2.0 tons per cubic yard, the planning weight is about 14.81 tons before hauling, dump fees, and machine time.

Inspect thickness, reinforcement, access, saw-cut needs, dump requirements, and whether the customer expects base cleanup. For a multi-truck haul-off, use the Dump Truck Cycle and Hauling Cost Calculator to test payload, dump delay, fleet-hours, and cost per ton.

Density source note: FHWA pavement-materials training describes normal-weight portland cement concrete at approximately 145–150 pounds per cubic foot, or about 1.96–2.03 tons per cubic yard. Demolished loads can differ because of reinforcing steel, voids, attached base, moisture, and mixed debris. Treat 2.0 as an editable example and prefer project tickets or recycler guidance. Review the FHWA source.

Verify tear-out and disposal assumptions

  • Check slab thickness in more than one spot.
  • Add time for rebar, wire mesh, and saw cutting.
  • Use dump tonnage, not only square footage.
  • Clarify whether haul-away and final grading are included.

Keep the final scope, assumptions, exclusions, allowances, change triggers, and post-job results with the estimate so future defaults are supported by evidence.

Common questions

Does the calculator detect slab thickness or reinforcement?

No. Measure the slab, inspect accessible edges, confirm reinforcing and base conditions, and state how concealed changes will be handled.

How should concrete weight be estimated?

Multiply calculated cubic yards by a documented tons-per-cubic-yard value. Replace the example density with recycler data, scale tickets, or project-specific evidence whenever possible.

Should disposal be billed from estimated or ticketed tons?

Use estimated tons for planning, then state in the quote whether disposal is included, allowed, passed through, or reconciled from accepted scale tickets.

Check removal production separately

If breaking or loading follows a repeatable measured cycle, use the Equipment Production and Unit Cost Calculator to test production and internal unit cost before returning here for concrete volume, disposal, mobilization, and final price.

Important disclaimerPlanning estimate only. Verify current costs, measurements, production, scope, access, customer requirements, contracts, permits, insurance, taxes, and local rules before quoting or committing money. This tool does not determine utility clearance, shoring, slope, ground stability, legal payload, securement, machine capacity, licensing, traffic control, environmental compliance, or safe operating procedure. Follow applicable law, plans, manufacturer instructions, and qualified safety guidance.
