Blocking and leveling

The mistake: treating 'it's on the ground' as the same as 'it's set'

The most common misunderstanding about container placement is thinking the job's done once the trailer pulls away and the box is sitting on the spot. Getting a container off the truck and getting it set are two different things, and skipping the second one is what causes the complaints people blame on the container itself months later.

A container that lands on uneven, unblocked ground looks fine the day it arrives. The problem shows up gradually, as one corner settles a fraction lower than the others and the whole steel frame twists slightly to follow it.

Why an unlevel corner turns into a real problem

A shipping container is its own frame. There's no separate foundation holding its shape, so if one corner sits lower than the other three, the box racks, just slightly, along its length. Steel is stiff enough that a small rack doesn't look like much from ten feet away.

The doors are where you feel it first. They're hung on that same frame, so a racked box makes them heavy to swing, out of alignment with the locking bars, and eventually hard to seal shut. What started as an inch of settling at one corner ends as a door that won't latch.

The correct approach: block first, check level, then leave

Blocking and leveling means setting solid concrete blocks, never hollow-web block, under each of the four corner castings and adjusting the stack at each corner until the box reads level end to end and side to side. On a good gravel pad this goes fast. On uneven ground it means jacking a corner, adding or pulling a block, and checking again until it's right.

The last step is the one people skip when they do it themselves: the door test. Open both doors fully, swing them back, close them, and drop the locking bars. If anything binds or a bar needs force, a corner still needs adjusting, and it's a five-minute fix while the truck is still there instead of a Saturday with a bottle jack later.

How it's handled on our deliveries

Blocking and leveling is included on every delivery within 75 road miles of Woodlawn, free, as part of the drop. Our crew sets solid blocks under the corners, checks the container level in both directions, and runs the door test before leaving your property, so a settled corner isn't something you discover after we're gone.
