TL;DR
Broken concrete is crushed, screened, and sold as road base and drainage aggregate, and it is one of the most successfully recycled materials in construction. Clean concrete usually tips cheap or free. Concrete with dirt, wood, or trash in it costs the same as garbage.
That single distinction, clean versus dirty, decides what a driveway tear-out costs you.
Clean Concrete Versus Dirty Concrete
Clean concrete means concrete, brick, block, and asphalt with nothing else in it. No soil clinging to the underside, no wire mesh sticking out, no plastic sheeting, no wood forms, no landscape fabric.
Dirty concrete is the same material with those things attached, or with excessive soil. A recycler measures it in whether their crusher and their downstream buyer will accept it.
Rebar is a partial exception. Most recyclers accept reinforced concrete because they pull the steel out mechanically. Wire mesh is more annoying, because it wads up and wraps around equipment.
The practical version for a homeowner: sweep the dirt off the slab pieces before they go in the pile, keep the pile separate from everything else, and do not use it as a place to throw the plastic sheeting. That is the whole difference described in what to do with broken concrete.
Breaking It Out
Concrete comes out in pieces sized by whatever is going to lift them. A crew with a hand jackhammer and wheelbarrows breaks a slab into pieces a person can carry, generally a foot or two across.
A skid steer and a hoe ram break bigger and load faster. A demolition contractor on a large job uses an excavator with a hydraulic breaker or a pulverizer that crushes the concrete and shears the rebar in one motion.
Rebar is cut with a torch, a cutoff saw, or a shear as pieces come free. Steel pulled at the site is scrap metal with its own value and should go in a separate pile, not in the concrete.
Size matters at the receiving end. Most recyclers cap the dimension they will accept because the crusher has a fixed jaw opening. Oversized slab pieces have to be broken further, sometimes for an extra fee.
What Happens at the Crusher
At a recycling yard, concrete goes into a jaw crusher that reduces it in one pass, sometimes followed by a cone or impact crusher for finer sizing.
A magnet over the discharge conveyor pulls out the rebar and mesh, which goes to a scrap yard. Air separation and hand picking take out the light contamination, meaning wood, plastic, and paper.
Screens sort the crushed product into sized fractions. The result is recycled concrete aggregate, sold by the ton in gradations that match what a project needs.
The whole operation is often mobile. Crushers get trucked to large demolition sites so the material never leaves the property, which saves enormous hauling cost on a big job.
Where Crushed Concrete Gets Used
| Product | Typical use |
|---|---|
| Road base | Compacted subbase under pavement and parking lots |
| Drain rock | Backfill behind walls, French drains, trench bedding |
| Fill material | Structural fill, site grading |
| Erosion control | Riprap and slope protection from larger pieces |
| Aggregate in new concrete | Limited use, depends on specification |
Road base is the volume market by a wide margin. Recycled aggregate compacts well, drains well, and performs comparably to virgin crushed rock for that purpose, at a lower price.
Using recycled aggregate in new structural concrete is more limited. Old concrete carries mortar on the aggregate faces, which absorbs water and affects the mix, so specifications restrict how much can be substituted.
Why Concrete Disposal Is Priced by Weight
Concrete is heavy. A cubic yard of broken concrete runs a couple of tons, and a small patio produces more weight than a truckload of furniture.
That is why concrete quotes work differently from ordinary junk quotes. Volume pricing does not apply, because a truck hits its legal axle weight long before the bed looks full. A pickup with a half ton rating can be overloaded by a surprisingly small pile.

Current Market Reality
Real quotes run above baseline when the slab is thick, heavily reinforced, or in a back yard with no equipment access. Breaking concrete by hand and carrying it out in buckets is slow, physical work and it is priced as such. Clean concrete tipping is cheap, so the cost you are paying is almost entirely labor and truck weight, which is the same pattern as construction debris removal cost.
What moves the price
| Scope | How it moves the price |
|---|---|
| Small patio or walkway section | Lowest of these |
| Standard one-car driveway | In between |
| Large slab or foundation removal | Highest of these |
| Clean concrete tipping at a recycler | Low, often far less than mixed debris |
| Thick or heavily reinforced slab, no equipment access | Adds to the price |
Every slab is different, so the real number depends on thickness, reinforcement and access. Enter your ZIP in the price box on this page for your instant price.
Reusing It Without Hauling It
If you have space, broken slab pieces have real on-site uses. Flat pieces work as informal retaining wall blocks, stepping paths, and border edging, and the look has a name in landscaping circles.
Larger chunks make functional erosion control on a slope. Small rubble makes decent base under a shed pad if it is compacted properly.
The limit is what your neighbors and your local code think about a rubble pile. A stack of broken concrete in a side yard is a code complaint waiting to happen in most jurisdictions, and it becomes a habitat for rodents. Reuse it or move it, but do not stage it indefinitely.
FAQ
Can I put broken concrete in a household garbage cart?
No. Carts have weight limits and automated trucks physically cannot lift an overloaded cart. Even a small amount of concrete in the bottom of a cart can trip the limit. Concrete needs a trailer, a bin, or a hauler.
Do concrete recyclers pay you for the material?
Generally not for household quantities. They typically charge a low tipping rate for clean concrete, sometimes nothing, because the crushed product has a market. What they will not do is take dirty concrete cheaply, since it becomes a disposal cost for them.
Is asphalt recycled the same way as concrete?
Similar process, different market. Asphalt is crushed and screened into reclaimed asphalt pavement, which goes back into new hot mix. It is often kept separate from concrete at the recycler because the buyers are different.
What about concrete with rebar in it?
Most recyclers accept it, since they pull steel with magnets. Very heavily reinforced concrete may cost more or need the steel cut out first. Loose rebar itself is scrap steel and should be piled separately, where it has some value.
Does painted or sealed concrete still recycle?
Usually yes. Surface coatings are a small fraction of the mass and are largely dealt with in crushing. Concrete with asbestos-containing material bonded to it, such as old floor tile mastic, is a different situation and needs assessment first.
Getting a Slab Off the Property
Concrete is the one job where a hauler's truck capacity matters more than anything else, and where a homeowner with a trailer usually underestimates the weight badly. Keep the pile clean, keep the dirt and wood out of it, and leave the loading to the hauler.
