Also called concrete piers, footing piers
A pier block is a single precast concrete footing, taller than a stacked masonry block, set under a container's corner casting to lift it off grade. They're a step between flat solid blocks and a poured concrete pier, used when a site needs more clearance under the container than blocking alone gives.
Most container sites are simple: firm, roughly level ground, and the corners sit on solid blocks a few inches high. Pier blocks show up on the sites that aren't simple. A yard with a low spot that pools water after every rain. A slope steep enough that one end of the container needs a foot of lift to come out level with the other. A spot where the owner wants a little daylight and airflow under the floor instead of steel sitting close to grass.
In any of those cases, a low, flat block doesn't get you enough height. That's the gap a taller precast pier fills, a single concrete footing built to carry a corner's load at a height a stack of flat blocks would struggle to hold steady.
Ordinary blocking, the setup our crew uses on a standard delivery, stacks solid concrete blocks flush and low under each corner, just enough to lift steel off wet dirt. A pier block does the same job at greater height in one piece rather than a stack, which matters because a tall stack of loose blocks is less stable than a single cast footing.
A poured concrete pier, the kind used under a permanent workshop build-out, goes a step further still: it's cast in place, often tied into the ground with rebar, and meant to anchor a structure that isn't going anywhere. A precast pier block sits between those two, taller than blocking, not anchored the way a poured pier is.
The container doesn't care how tall its footing is. What decides whether flat blocks, pier blocks or a poured foundation is right is the ground: how much slope there is to make up, how wet the low corner gets, and whether the box is a movable storage unit or the start of a permanent structure.
A movable storage box on uneven ground is usually still a blocking job, just a taller one. A container becoming a workshop or office on the same site is a different conversation entirely, and that's where a poured pier or slab, and a call to your county, belongs.
Our crew sets and levels every container we deliver on solid concrete blocks, the standard low setup, free within 75 road miles of Woodlawn. If your site needs pier blocks or a poured foundation for extra height or a permanent build, that's ground work done ahead of delivery by you or a local contractor, and we'll set the container on whatever solid, level footing is waiting when the truck arrives.
We'll tell you honestly what your footing needs before the truck rolls.
Same-day reply. We'll send a real number, a real delivery window, and any photos we need to confirm fit.
You'll hear back from us today (or first thing tomorrow if it's late). For anything urgent, call (276) 237-6144.
