Cured concrete weighs about 150 lbs per cubic foot - roughly 4,000 lbs per cubic yard - so a modest 10x10 patio slab is already 2.5 tons and a two-car driveway runs over 7. Enter your dimensions below for an instant weight estimate, then use the real-world examples and disposal guidance to plan the haul.

Real-world examples at 150 lbs per cubic foot. Check the math yourself: length x width x thickness (in feet) x 150.
| Project | Concrete | Weight | Tons |
|---|---|---|---|
| Sidewalk section (3' x 30', 4" thick) | ~30 cu ft | 4,500 lbs | 2.25 |
| Patio slab (10' x 10', 4" thick) | ~33 cu ft | 5,000 lbs | 2.5 |
| Single-car pad (10' x 20', 6" thick) | ~100 cu ft | 15,000 lbs | 7.5 |
| Two-car driveway (12' x 24', 4" thick) | ~96 cu ft | 14,400 lbs | 7.2 |
| Large driveway (20' x 20', 4" thick) | ~133 cu ft | 20,000 lbs | 10 |
Figures current as of July 2026, based on the standard 150 lb/cu ft for cured concrete.
Look at the table above and the reason is obvious: a standard dumpster filled with concrete would weigh more than the truck hauling it can legally carry. Concrete jobs need a dedicated heavy-debris container - usually a low-sided 10-yard rated for the tonnage - matched to your actual weight.
In most service areas you can book a heavy-debris container online from our order page with real concrete, dirt, and mixed-load pricing for your ZIP. For the best price, run your numbers in the calculator and call (866) 858-3867 with the result - reps match the container and rate to your exact tonnage, and callers save an average of $50 or more on heavy loads.
One money-saver worth knowing: clean, pure concrete loads can often be routed to recycling as crushed aggregate, which some facilities take at a reduced rate. Keep trash and lumber out of the pile and say “clean concrete” when you call.

Cured concrete weighs about 150 pounds per cubic foot, which works out to roughly 4,000 pounds - two tons - per cubic yard. Broken concrete in a dumpster settles with air gaps, so a loose cubic yard of rubble typically weighs 3,000 to 4,000 pounds depending on piece size.
A 10 by 10 foot slab at the standard 4 inch thickness contains about 33 cubic feet of concrete and weighs right around 5,000 pounds, or 2.5 tons. At 6 inches thick, the same slab jumps to about 7,500 pounds.
Small amounts mixed with other debris are usually fine, but concrete-heavy loads need a dedicated heavy-debris container with the right weight rating - a full-size dumpster filled with concrete would exceed legal road weight for the truck hauling it. In most areas you can book a heavy-debris container online with real local pricing, and for the best rate on your exact tonnage call (866) 858-3867.
It depends on tonnage and your local market. Pure concrete loads often cost less to dispose of than mixed debris because clean concrete is recyclable as crushed aggregate - some facilities accept it at a reduced rate. Call (866) 858-3867 with your calculator result and a rep prices the right heavy-debris container for your exact ZIP.
Yes - clean concrete is one of the most recycled construction materials in the country. It gets crushed into aggregate for road base, fill, and new concrete. Keeping your load free of trash, wood, and rebar-tangled debris makes it easier to route to recycling, which can lower your disposal cost.
