The interior dimensions of our 20-yard dumpster are 17 feet long, 7 feet wide and 4 feet tall. Although the exact measurements may vary by manufacturer, the capacity and volume of the 20-yard rental container will be the same. A cubic yard of concrete weighs approximately 2,000 pounds (1 ton). The maximum amount of concrete you should load into any dumpster is approximately 8 tons or 16,000 pounds.
That's roughly 3 to 4 trucks loaded with concrete. If you're looking to rent a dumpster to dispose of concrete, there are some important questions to consider. If you only partially fill your container with concrete and you want to fill the rest with heavy materials, such as roofing, plaster or drywall, the truck may not be in a position to get the container out of where it was placed.
