How we verify our calculatorsChoose the Right Removal Plan
The cheapest plan is not always the safest one. Match the slab, access, weight, and disposal path before you rent tools or order a dumpster.
Small patio
4 in thick, no rebar, open access, one dumpster load.
Sidewalk panels
Cut control joints cleanly, keep sections small, protect lawn edges.
Driveway or slab
Weight and hauling matter more than square footage alone.
Foundation wall
Structural risk, rebar, permits, and multiple heavy loads.
Disposal route
Clean concrete often goes to a recycler. Painted, contaminated, or mixed debris usually costs more and may need a separate dumpster.
Weight limit
Concrete fills dumpsters by weight before volume. Confirm the ton limit and overage fee before delivery.
Next surface
Plan grading after removal. A bare low spot can hold water, wash soil away, or delay the replacement pour.
Pro Tips
Measure thickness at an exposed edge or control joint before pricing the job. A slab that looks like 4 inches can be 6 inches near the driveway apron or garage edge.
Ask the dumpster company for both yard size and concrete ton limit. Concrete usually maxes out the weight allowance long before the container looks full.
Separate clean concrete from soil, asphalt, trash, wood, and metal. Clean loads are more likely to be accepted by a recycler at a lower fee.
If replacement concrete is part of the project, price it before demo with the concrete slab calculator. Removal is only the first half of the job.
Saw-cut the edge where the old slab meets concrete that will stay. A clean cut protects the remaining driveway, sidewalk, garage floor, or porch step.
After the concrete is gone, use the excavation calculator to estimate grading or fill if the subgrade needs correction.
If you discover wire mesh or rebar, slow down and cut steel as it appears. Pulling tangled reinforcement can crack concrete you planned to keep.
How the Calculator Works
This estimator starts with the physical slab, not a flat project price. Length, width, and thickness produce area, cubic yards, and debris weight. That matters because a small thick apron can cost more to haul than a larger thin patio.
1. Measure
Use the actual slab thickness when you can. Check edges, control joints, broken corners, or an old core hole.
2. Classify
Pick the closest structure type. Driveways, slabs, and foundations price higher because they are heavier or harder to break cleanly.
3. Haul
The calculator converts debris to tons, chooses a dumpster size, and rounds up loads by weight capacity.
What the estimate includes
The low and high cost range includes demolition labor plus hauling. Rebar adds 10% to demolition because crews must expose and cut steel. The estimate does not include replacement concrete, permits, saw-cutting specialty work, hidden utilities, drainage repair, or subgrade rebuild.
Formulas
Area = Length x Width
Volume = Area x (Thickness / 12)
Weight (tons) = Volume (cu ft) x 150 lbs / 2,000
Demo Cost = Area x Structure Demo Rate x Rebar Multiplier
Hauling Cost = Area x Structure Hauling Rate
Total Cost = Demo Cost + Hauling Cost
Dumpster Loads = Weight / Dumpster Capacity, rounded up

Common Questions
What makes one concrete removal job cost more than another?
The biggest drivers are thickness, reinforcement, access, and disposal. A thin patio with open access may price close to the low end. A driveway apron, reinforced slab, or foundation wall needs more breaking time, steel cutting, and heavier hauling.
Should I remove concrete myself or hire a pro?
DIY makes sense for small, unreinforced slabs around 4 inches thick with easy dumpster access. Hire a pro for rebar, wire mesh, slabs over 6 inches thick, tight access, large driveways, foundation walls, or any area tied into a structure.
How do I estimate an irregular slab?
Break the area into rectangles, calculate each one, then add the totals. For curved patios or odd walkways, measure the longest length and average width, then add a small buffer for hidden thick spots or uneven edges.
Why does dumpster size not match the cubic yards exactly?
Concrete is limited by weight. A 20-yard dumpster may have enough space for more broken concrete, but the hauler may cap it around 6 tons. Overweight fees can cost more than ordering the right container or extra pull up front.
Can broken concrete be recycled or reused?
Clean concrete can often be recycled into road base or crushed aggregate. Some projects reuse chunks as fill, but do not bury concrete near foundations, utilities, drainage pipes, or areas that need compacted structural base.
What if I find rebar or wire mesh after I start?
Stop treating it like a simple slab. Break concrete into smaller pieces, expose the steel, then cut it with the right metal blade or bolt cutters. Reinforcement slows the job and can make debris harder to load safely.
Do I need to saw-cut before removal?
Saw-cut any edge that touches concrete you want to keep. That includes garage floors, porch steps, sidewalk panels, driveway aprons, and foundation edges. The cut gives the break a clean stopping point.
What should I plan after the concrete is removed?
Plan grading, base material, drainage, or replacement concrete before demo day. A removed slab often leaves low soil, soft subgrade, or trapped water that needs correction before the next surface goes in.
Project-Specific Removal Playbooks
Back Patio Replacement
10x10 ft, 4 inches
$300 - $600, about 1.25 tons
Plan: DIY is realistic if the slab is unreinforced and the dumpster can sit close to the work area.
Watch: Check slope after removal. Patios often hide low soil near the house that needs regrading before the next pour.
Driveway Panel Tear-Out
20x12 ft, 6 inches
$1,080 - $1,800, about 5.6 tons
Plan: Plan for a 20-yard concrete dumpster or direct haul-away. Saw-cut the panel edges if nearby driveway sections will stay.
Watch: Aprons and edges can be thicker than the middle. That can push the load over the dumpster weight allowance.
Sidewalk Section Reset
40x4 ft, 4 inches
$480 - $960, about 2 tons
Plan: Break at existing control joints, stack pieces near the pickup point, and protect lawn or paver edges.
Watch: Public sidewalks may require city approval, inspection, or a specific replacement detail.
Foundation or Retaining Wall
80x8 ft, 8 inches
$4,480 - $8,960, about 20 tons
Plan: Treat this as professional demolition. Expect equipment access, steel cutting, engineered shoring, or staged hauling.
Watch: Do not remove walls tied to a house, footing, porch, or grade change without structural guidance.
Pre-Demo Checks That Prevent Expensive Surprises
Locate utilities and drains
Call 811, then look for downspout lines, irrigation, low-voltage lighting, pool plumbing, or old conduit that may not be marked.
Confirm slab thickness
Measure at multiple edges if possible. Thickened edges, aprons, and old patch areas can change weight, dumpster loads, and tool choice.
Choose a debris route
Know where broken concrete will go before the first cut. Wheelbarrow distance, stairs, gates, and soft lawns change labor fast.
Protect concrete that stays
Saw-cut clean edges, avoid prying against remaining slabs, and brace nearby pavers, steps, garage floors, or porch edges.
Plan steel handling
Wire mesh and rebar need cutting as they are exposed. Do not leave steel sticking out of broken chunks or partial slabs.
Schedule the next surface
After removal, fix grade, drainage, and base material before rain turns the opening into a muddy low spot.
