Concrete Disposal Dumpster

How much concrete can I put into a dumpster?

The weight of a concrete-filled, 12-yard dumpster, weighs roughly 12 tons. 

The most amount of concrete that we can handle at one time is a 12-yard dumpster that is NOT loaded higher than the sides of the dumpster. 

A 1 cubic yard mixture composed of gravel, stone, or sand can weigh more than 3,000 pounds. However, 1 cubic yard of asphalt or concrete weighs about 4,000 pounds. 

A 4 inch thick, 10’ x 10’ pad of concrete weighs around 4,000 pounds and measures to be roughly 1.23 cubic cards. If you need to calculate the weight of concrete by cubic foot, divide the cubic yard weight by 27. 

One major factor to keep in mind is how you load your concrete. This can dramatically change the volume of your load. 

Please note that the information above is only for the recycling of concrete (clean concrete). There is no top cap on a clean dumpster. 

How much concrete can I put in a regular debris dumpster?

You can fill a 12-yard dumpster, fill a 20-yard dumpster 1/2 full, and you can fill 1/3 of a 30-yard dumpster. 

If you only partly fill your dumpster with concrete and want to fill the rest with heavy materials such as roofing, plaster, or drywall, the truck may not be abv to remove the dumpster from where it was placed. This will require you to rent a second container. In addition, the dumpster will be subject to a ton cap and may cost hundreds of dollars in addition to the included tonnage of a regular dumpster rental.

How to Calculate Cubic Feet & Yards For Trash and Concrete

The formula: Number of Cubic Yards = Length (in feet) X Width (in feet) X Depth (in feet) = __ ÷ 27. Simply multiply the three dimensions together to find the number of cubic feet, then divide by 27 to find the number of cubic yards.

To convert Cubic Yards to Tons*: Cubic Yards x 1.4 = Tons. To convert Tons to Cubic Yards*: Tons ÷ 1.4 = Cubic Yards.

Shingle Information

One square equals three bundles of shingles. Three bundles cover 100 square feet. You should expect each square of three-tab shingles to weigh close to 250 pounds. However, if you have architectural squares, you should expect them to weigh around 360 pounds. There is also the problem of multiple layers of roof that might be coming off. If you have a 20 square roof with two layers of shingles coming off, you’ll need a roll-off dumpster that can handle at least 40 squares.

Here’s an estimate of the container sizes and the number of squares that they can handle:

  • 30-yard dumpster: 90 squares = Est. 7,000 - 10,000 pounds ( Est. 3.5 tons - Est. 5 tons )
  • 20-yard dumpster: 60 squares = Est. 6,000 pounds ( Est. 3 Tons )
  • 15-yard dumpster: 45 squares = Est. 4,000 - 6,000 pounds ( Est. 2 tons - Est. 3 tons )
  • 10-yard dumpster: 30 squares = Est. 4,000 - 6,000 pounds ( Est. 2 tons - Est. 3 tons )

General Material Information

  • 40 cubic yard dumpster: Equivalent to about 230-250 33-gallon trash bags, 12 pickup truck loads or 360-540 wheelbarrow loads.
  • 30 cubic yard dumpster: Equivalent to about 170-190 33-gallon trash bags, 9 pickup truck loads or 270-405 wheelbarrow loads.
  • 20 cubic yard dumpster: Equivalent to about 110-130 33-gallon trash bags, 6 pickup truck loads or 180-270 wheelbarrow loads.
  • 1 cubic yard of mulch weighs about 1,000 pounds, depending on dryness.
  • 1 cubic yard of soil weighs roughly 2,200 pounds.
  • 1 cubic yard of sand, gravel, or stone can weigh more than 3,000 pounds.
  • 1 cubic yard of roof shingles can weigh between 4,200 - 7,000 pounds.
  • 1 cubic yard of concrete or asphalt weighs about 4,000 pounds.
  • 1 cubic yard of drywall weighs about 500 pounds.
  • 1 cubic yard of carpet can weigh between 2,300 - 3,200 pounds.

Additional considerations when renting a dumpster for concrete.

Before you dispose of your concrete, you should ask yourself a few questions: What size dumpster do I need? How many dumpsters do I need? How many cubic yards of concrete do I have? 

It’s important to note that concrete can also be recycled, so make sure that you are disposing of “clean concrete”. This means that your concrete has no paint, no backwash (slurry), no dirt, wood, or garbage of any kind.

The weight of your concrete depends entirely on the type of concrete that you have. For example, concrete slabs and concrete chunks both weigh very differently. With this being said, it’s important that you keep an eye on how much of each type of concrete you are putting in your dumpster. 

Safety is a top priority. Make sure that your dumpster is always placed in a level area to prevent tipping or sliding. If there is anything that you are still unsure of, call your local dumpster company and they will be able to assist you in answering all of your questions.
