Not the right choice for: Anything heavy or dense - concrete, brick, clay and the like will overload a 40 yard drastically. Heavy debris always goes in a 10 yard. This size is purely for high-volume, light material.
All about volume
The 40 yard exists for one reason: maximum capacity for light, bulky debris. On a big commercial strip-out, a major renovation or a large land-clearing job, it means fewer swaps and less downtime because there is simply more room before it is full.
Volume and weight are different limits
The 40 yard gives volume, not extra weight allowance. Fill it with anything dense and it passes the legal hauling weight while it still looks half empty. Keep it for light material - packaging, framing, cleared vegetation, general bulky waste - and send heavy rubble to a 10 yard.
It needs real space
This is a large container. It needs a wide, firm, level spot, a long straight approach and generous overhead clearance for the truck. On many residential lots - and on tight ones especially - it will not fit, and two 30 yards may be the better answer. We will tell you honestly which works.

(720) 407-848540 Yard Dumpster: common questions
When do I need a 40 yard instead of a 30?
When you have a large volume of light, bulky debris and the space to place the container - big construction, commercial renovations, major land clearing. For household cleanouts a 30 is usually enough; the 40 is for high-volume project waste.
Can I put heavy debris in a 40 yard?
No - it would overload badly. The 40 is for light, bulky material only. Concrete, brick, tile and clay go in a dedicated 10 yard to stay within the legal hauling weight.
Will a 40 yard fit on my property?
It needs a wide, firm spot, a long straight approach and good overhead clearance, so it does not suit many residential lots. Where it will not fit, two 30 yards often works better - send a photo and we will advise.
