Dirt and Concrete Dumpster Rental in Concord, CA
Short answer: BBP Dumpster rents a flat rate 10 yard container for single-material loads, $550 for clean concrete and $650 for clean dirt, with no weight limit and no scale ticket. Delivery, pickup and recycling are included, in Concord and across the Bay Area.
Every other container we run is priced with a tonnage allowance because mixed debris is unpredictable. Dirt and concrete are the opposite: entirely predictable, extremely heavy, and accepted at recycling facilities rather than landfills. That combination is what makes a flat rate possible.
The practical result is that a slab job stops being a guess. On a standard 10 yard at $465, three tons of concrete would add $330 in overage. Here the same load is $550 and nothing is measured.
The One Rule That Matters
One material, and nothing else. Concrete with rebar still inside it is fine, since the steel is separated magnetically after crushing. A single sheet of plywood, a bag of household trash or the roots from a tree is not, because the facility that takes clean rubble will not take mixed debris.
When a load is reclassified at the gate it is billed as general debris by weight, and on material this dense that is always more expensive. If there is wood or vegetation in the pile, say so when you book and we will price it correctly the first time.
How Much Fits
Roughly 250 to 300 square feet of a four inch slab, which covers a typical single driveway or a medium patio. By weight that is close to 7,500 pounds of concrete, since a four inch slab runs about 50 pounds per square foot. Excavation fill works out similarly by volume. The container is deliberately small: at roughly 4,000 pounds per cubic yard, a 10 yard box of concrete already approaches the 10 ton legal limit for the truck, and no larger container could be hauled full.
How Concrete Actually Gets Recycled
Clean concrete goes to a crushing facility rather than a landfill, where it is broken down into aggregate that gets reused in new construction, mostly as road base and fill material. That end use is the entire economic reason a facility will take it for a flat rate instead of charging by the ton: crushed concrete has resale value, while general debris only has a disposal cost.
Dirt Has Extra Conditions
Clean fill means soil with no roots, sod, rock or debris, and it has to be dry. Wet dirt is refused at the facility, and every dirt load must be covered by the customer before pickup, because uncovered soil cannot legally travel on the road. Those two conditions are the most common reason a dirt container gets delayed.
For mixed demolition where concrete is only part of the job, the 20 yard or 30 yard is the right container instead. On large demolition where concrete is only part of the debris, the 40 yard carries the rest.
