Important Information on Dumpster Box Rentals

Weight limits- Trucks have a maximum legal weight that they can carry. This calculates out to approximately 10 tons of material that we can haul legally. If you have a question about the weight of your material, please contact us for a free job walk. This can save you money later on overweight and service charges.

Access- Roll-off trucks need about 35 feet of straight-line access to place box. Also, please check overhead for tree limbs, power or telephone lines, etc.

Hazardous Materials- We do not haul hazardous materials (hazmat). If you have hazmat or think you might have hazmat, you need to call a hazmat specialist.

How to calculate cubic yards.- Think of a Rubik’s cube, three feet deep, three feet high and three feet wide. There are 27 cubic feet in a cubic yard (3x3x3). Your load can be estimated the same way. If you have a pile 20 feet wide, 10 feet deep and 4 feet tall : 20ft X 10ft X 4ft equals 800 cubic ft.  Divide 800 cubic ft by 27 cubic ft per cubic yard equals 29.63 cubic yards.  With this calculation, you can estimate the size of roll-off box that you need.
