Frequently Asked Questions
How much does concrete weigh per cubic yard?
Standard concrete weighs approximately 4,050 pounds (about 2 tons) per cubic yard. Reinforced concrete with rebar is slightly heavier at around 4,185 lbs per cubic yard. Lightweight concrete can weigh as little as 2,970 lbs per cubic yard.
How much does a concrete slab weigh?
A standard 4-inch thick concrete slab weighs approximately 50 lbs per square foot. A 10×10 foot slab would weigh about 5,000 lbs (2.5 tons). A typical two-car driveway (20×20 feet at 4 inches thick) weighs approximately 20,000 lbs or 10 tons.
What size dumpster do I need for concrete?
Because concrete is so heavy, most haulers recommend using a smaller dumpster filled less than halfway rather than a large one. A 10-yard dumpster is typically recommended for up to 1.5 tons of concrete, a 15-yard for up to 3 tons, and a 20-yard for up to 5 tons. Always confirm the weight limit with your rental company before loading concrete.
How many cubic yards is a standard concrete driveway?
A standard two-car driveway measuring 20 feet wide by 20 feet long at 4 inches thick contains approximately 5 cubic yards of concrete (20 × 20 × 0.33 ÷ 27 = 4.9 yd³), weighing about 10 tons.
