Most driveways take a container without a mark on them. The ones that do not are rarely a surprise afterwards — the damage happens in a handful of predictable places, for reasons that are easy to design around if anyone thinks about them before the truck is loaded. Three things decide it: what the surface is, where the box sits, and whether anything went under it.
Flag the surface in the booking notes and the driver brings boards.
Not because it is heavy in general. A driveway carries vehicles every day without complaint. What is different about a roll-off is where the load lands: the box rests on two steel rails and rolls on and off on wheels, so everything it carries arrives through a few small contact patches instead of being spread across the slab. That concentration is the mechanism. Everything below is a way of widening it.
The second factor is time. A vehicle parks and leaves. A container sits in one spot for days, sometimes through a hot week, and a surface that shrugged off the delivery can still take a set from the same load left in place. That is why the same box on the same driveway can be completely fine on one job and leave a mark on the next.
The third is what goes in it. A box filled with tear-off is a different proposition from one filled with slab, and the difference lands entirely on the surface underneath. The size guide covers what each container takes if you are still deciding.
The fix the industry settled on is the simple one. Put wood between the steel and the surface — three-quarter-inch plywood, or two-by-six or wider planks — under the rails and across the line the wheels track. The wood spreads what was landing on a few inches across several square feet, and it takes the scuffing that would otherwise land on your finish.
We bring it. Tell us at booking that the container is going on a finished driveway and the driver leaves with boards on the truck. This is the part worth being blunt about: it cannot be decided on arrival. A driver standing in front of a slab he was not told about has no dunnage with him, and the choice at that point is to set the box down bare or to leave. One sentence in the booking notes removes that entirely.
This is standard on the 15-yard roll-off and the 20, which are the sizes that most often go on a driveway rather than on open ground.
Asphalt. It softens as it warms. That makes summer the season to think about, and it makes duration matter more than it does on concrete — a container parked in one spot through a hot stretch can leave a depression where the rails sat even though nothing cracked. Spread the load as widely as the boards allow, and if the job runs long on a hot week, it is worth asking whether the box can sit somewhere else.
Concrete. It does not soften, so the failure is cracking rather than deformation, and it happens where the slab is weakest: the unsupported edge of a panel, the expansion joints, and anywhere the ground underneath has settled and left a void. A panel that rocks slightly when a wheel crosses it is telling you exactly where not to set a container. Keep the box toward the middle of a sound panel, off the joints.
Pavers, stamped work, and anything decorative. Treat it as a surface not to use. Where there is no alternative, say so at booking and we will talk through what is possible — sometimes the answer is that the box goes on the street or on open ground and the crew carries a little further.
Placement does more for a driveway than any amount of protection under it. Four things to avoid, in the order they cause problems:
The flat run near the garage is usually the answer. If the only workable spot is a tight one, that is a separate conversation and a solvable one — what actually stops a delivery covers the approach, the overhead and the turning room a truck needs.
Concrete, dirt, rock, brick and asphalt go in the 10-yard rock box, which is the only container rated to carry them. It is also the shortest box we run, and that combination is exactly the one to think about on a driveway: a dense load in a short container concentrates more on less. Boards are not optional there, and neither is the placement conversation.
Demolition on an occupied property usually produces both — the structure in a large roll-off and the slab, footings or old apron in a rock box. Where both containers are coming to the same address, say so at booking so the sequence and the two set spots get planned together rather than the second one arriving as a surprise.

(425) 522-3717Take pictures of the driveway before the truck arrives, including the cracks and stains that are already there. Steel leaves cosmetic marks that look worse than they are, and most driveways have a history nobody remembers until they are looking for it. A dated set of photos settles the question for everybody — it protects the property owner who genuinely has new damage, and it protects the contractor who does not.
It takes a minute and it is the only part of this that costs nothing at all. Do it on rental properties and commercial lots too, where the person who booked the container is rarely the person who will inspect the surface afterwards.
Four things, and they take one line in the notes: what the surface is (asphalt, concrete, pavers, gravel), roughly how long the container will sit there, what is going in it, and anything about the approach that is not obvious from the road. That is enough for dispatch to send the right truck with boards on it and to flag a spot that is not going to work before anybody is standing on the drive.
We deliver across both service areas — every city we reach in King County and the Pierce County list — and driveway placement is a daily conversation on both sides of the line.
Usually not, and where it does the reason is almost always predictable. Damage comes from load arriving on a few small contact patches rather than being spread across the slab, so the fix is to spread it: plywood or planks under the rails and where the wheels track. Tell us the surface when you book and the driver brings dunnage on the truck. Older slabs, edges, seams and anything sitting on ground that has already settled are the places to be careful, and they are worth pointing out before delivery rather than after.
We bring it. Say at booking that the container is going on a finished driveway and the driver arrives with boards and sets the box on them. What we cannot do is decide that on arrival for a site nobody flagged, because the boards have to be on the truck when it leaves. That one sentence at booking is the whole difference.
They fail differently rather than one being safer. Asphalt softens in warm weather, so the risk there is a depression left behind where the load sat, and it is worst on a hot week with the container in one spot for a long stretch. Concrete does not soften, but it cracks — at the edges, along the expansion joints, and anywhere the slab has lost support underneath. On asphalt spread the load as widely as you can; on concrete keep it off the edges and joints and toward the middle of a panel.
