Dumpster Weight Limits: How Weight Is Billed

Every dumpster size has a weight limit, and your load is weighed on the landfill's certified scale. Weight over the tons included in your size costs $75 per ton, by the exact pound, and the scale ticket comes with your invoice.

How is dumpster weight measured?

Dumpster weight is measured on the landfill's certified truck scale. The truck is weighed full (gross weight), then empty (tare weight, the truck and empty box). Net weight is gross minus tare. That net weight is compared with the tons included in your dumpster size.

We email a digital copy of that certified scale ticket with your final invoice, so you see the exact printout the charge comes from.

How much is the overweight fee?

The overweight fee is $75 per ton over your included weight, charged by the exact pound. A 20-yard includes 3 tons. If the scale ticket shows 3.4 tons net, you are 0.4 ton over and pay $30. There is no rounding up to the next half ton or full ton.

0.4 tons over × $75 = $30.00 added to your final invoice. The 20-yard includes 3 tons.

Which materials go over the weight limit fastest?

Concrete, dirt, brick, tile, plaster and shingles go over the weight limit fastest. Normal-weight concrete is about 150 lb per cubic foot, so a 10 × 12 ft patio 4 inches thick is about 3 tons. Lumber, furniture and carpet are light and fill the box long before they get heavy.

How do I avoid an overweight dumpster charge?

Avoid an overweight charge by matching heavy debris to a small dumpster, filling concrete and dirt only halfway, and keeping rain out. Weigh out your heaviest material first: count shingle bundles or measure the slab. Then compare that weight with the tons included in your size.

  1. Run the roof calculator for shingles, or measure slabs for concrete.
  2. Pick the size whose included tons cover your heavy debris.
  3. Tarp the dumpster when rain is forecast. Wet drywall and carpet soak up water.
  4. Keep heavy debris low and spread across the floor of the box.

When will I get the final bill?

The final invoice arrives by email 3 to 5 business days after pickup, once the landfill processes our disposal logs. It lists any overage, extra days and $50 items, with the certified scale ticket attached. That invoice is the final bill for the rental.

Dumpster weight questions

Do you round up to the next ton?
Knox Bros does not round up. Overage is charged pro-rata by the exact pound from the official digital weight ticket. 300 pounds over is 0.15 ton, or $11.25.
Can I see the scale ticket?
A digital copy of the certified landfill scale ticket comes attached to every final invoice. It shows the gross, tare and net weight for your load.
Does rain really add weight?
Rain adds weight because wet debris holds water. Drywall, carpet, cardboard and yard waste soak up the most. Cover the dumpster with a tarp when rain is forecast.
What happens if the dumpster is too heavy to haul?
If debris is above the rim or a heavy-debris load is past the halfway line, the driver can't legally haul it. A $125 dry-run fee applies, and the extra debris has to come out before pickup.
