We recommend that you pack the debris in a way that best reduces wasted space. Heavy material should be at the bottom of the container and should be spread evenly throughout. The top of the dumpster is the loading line; nothing should go past it, as it becomes a hazard for both our drivers and other people on the road. We are required by law to cover the dumpster with a tarp before transporting it; if we are unable to for whatever reason, we reserve the right to have offloaded anything we cannot transport, or the right to leave the dumpster altogether and charge a trip fee. We will always do our best to let you know if we run into any situations like this.
