Concrete is the project that breaks every instinct about dumpster size. The pile looks tiny, so people reach for a big box, and the math punishes them. With heavy material, smaller is almost always smarter.
Because a roll-off has a weight cap, and concrete reaches it long before the volume cap. Every container has two limits: cubic yards of space and tons the truck can legally haul. Concrete, brick, and dirt are so dense that a load hits the weight limit when the box is only a third to half full. The remaining space is air you are not allowed to fill, so a bigger box is wasted money.
This is the opposite of how most people picture dumpster sizing. With furniture or cardboard, you fill the box to the top and never get near the weight cap. With concrete, you hit the cap first and the volume never matters. That flip is why pros load heavy material into a small 10-yard with a painted fill line, while a homeowner who rented a 30-yard for a patio tear-out ends up paying for two-thirds empty space.
Concrete is heavy enough that a small slab produces a serious tonnage. Broken concrete weighs roughly 4,000 pounds per cubic yard, so even a few cubic yards is several tons. A 10-yard box filled with concrete to the top would be far too heavy for the truck to haul legally, which is exactly why these boxes carry a fill line, often near the halfway mark.
| Material | Rough weight | What that means for the box |
|---|---|---|
| Broken concrete | ~4,000 lbs per cubic yard | Fill to the line, not the top. |
| Brick and block | ~3,000 to 4,000 lbs per yard | Dedicated 10-yard. |
| Dirt and soil | ~2,000 to 2,700 lbs per yard | Heavy when wet, watch the line. |
| Asphalt | ~3,800 lbs per yard | Keep it separate from trash. |
The fill line is not us being cautious, it is the law of physics meeting axle-weight rules. A driveway tear-out in Overland Park or a patio demo in Blue Springs can look like a half-day of light work and still produce four or five tons. We spec the included tonnage to the job and explain the line before the drop so the truck can legally take what you load. Our weight-limit guide goes deeper on how overage is billed.
Yes, and it can save you money. Clean concrete and brick, with no rebar, dirt, wood, or trash mixed in, can go to a recycling yard that crushes it into reusable aggregate. That path usually costs less to dispose of than mixed debris headed to a landfill. The catch is the word clean: one load contaminated with trash loses the recycling rate and goes to the landfill at the higher cost.
So the smart plan for a project with both heavy and light debris is two boxes, not one. Put the clean concrete in its dedicated 10-yard so it qualifies for recycling, and put the wood, drywall, and general trash in a separate container. Mixing them costs you twice: the heavy load goes over weight, and the contaminated concrete loses the cheaper disposal route. Contractors running larger jobs lean on our construction debris service to keep the streams split.
A 10-yard heavy-debris box for a 7-day rental usually runs $250 to $350, with a set tonnage allowance sized for dense material. Because concrete is loaded by weight, the included tons matter more than the cubic yards, and we quote that allowance up front along with the fill line. Heavy loads are quoted carefully, since the weight does the talking, not the volume.
Overage past the included tonnage usually runs $50 to $90 per ton, which is the number that bites homeowners who underestimate concrete weight. That is the whole reason we size the box and the allowance to the job before you book. Extra days past the week run about $10 to $20 each, haul distance to the outer suburbs adds a little, and a street-placement permit, if your box cannot sit on the driveway, usually runs $25 to $100. We give you the all-in figure first. See the FAQ for more detail.
A 10-yard dumpster is the right box for concrete, brick, dirt, and other heavy material in almost every case. These materials are so dense that even a 10-yard is loaded by weight, not volume, and a fill line marks how high you can go. A bigger box would hit its legal weight limit only a third full, so the extra size is wasted air you cannot use.
Because the truck has a legal axle-weight limit and concrete is dense enough to blow past it fast. A roll-off filled with concrete to the top would be far too heavy to haul safely or legally. That is why heavy-material boxes have a painted fill line, often around the halfway mark, that keeps the loaded weight under the cap so the driver can actually take it.
It is best to keep clean concrete, brick, and dirt in their own dedicated box. Mixing in wood, drywall, or trash defeats the lower recycling rate clean concrete can earn and pushes the load over weight. If you have both heavy material and general debris, the cheaper plan is usually a small heavy box plus a separate container for the light stuff.
Often, yes. Clean concrete and brick with no rebar, trash, or dirt mixed in can go to a recycling yard that crushes it for reuse, which usually costs less to dispose of than mixed debris at a landfill. Keeping the load clean is the key. We will tell you whether your material qualifies and route it to keep your cost down.
A 10-yard heavy-debris box for a 7-day rental usually runs $250 to $350, with a set tonnage allowance for the dense material. Because concrete is loaded by weight, we quote heavy loads carefully and explain the included tons and the fill line up front. Overage past the allowance usually runs $50 to $90 per ton, so right-sizing the job matters.
Tell us what you are demoing and roughly how much, and we will size a heavy-debris box, set the tonnage allowance, and route clean concrete for recycling where it saves you money. Fill line and all-in price explained before the drop.
