Site prep for a shipping container

A little prep before the truck arrives makes a container last longer and keeps the doors working. Here's what matters, in order.

1. Pick the spot

Somewhere the truck can reach in a straight line, with room overhead. See how delivery works.
High ground that drains, not a low spot where water collects.
Room at the door end to swing both doors fully open (about 8 ft) and to walk in.
Clear of septic tanks, drain fields, buried lines and tree roots you care about.
Within any setback or placement rules your city, county or HOA sets. Check before delivery.

2. Give it a solid base

A container rests on four steel corner castings. The goal is firm, level support at those corners and keeping the floor out of standing water.

Base	Good for	Notes
Compacted gravel pad	Most sites	Drains well and spreads the load. A few inches of compacted crushed stone, a little larger than the container's footprint.
Railroad ties or treated timbers	Farms, yards, quick setups	Lay them across the ends (and the middle on a 40ft) on firm ground.
Concrete blocks or piers	Uneven ground	Solid blocks under each corner, shimmed level. Keeps air moving underneath.
Concrete slab or asphalt	Existing hard surfaces	Great if it's already there and thick enough. Thin or old paving can crack under the corners.

3. Get it level

A twisted container is the main reason doors won't close. Use a long level or a string line across your pad or blocks before delivery. A slight fall toward the doors is fine and helps water run off the roof.

4. Clear the path

Move vehicles, trailers and anything along the route. Trim low branches. Mark the four corners of the drop spot with stakes or paint so the driver knows exactly where you want it.

5. Think about after delivery

Condensation: steel sweats when temperatures swing. Vents and moisture absorbers help, especially in humid climates.
Security: a good padlock, ideally inside a welded lock box.
Anchoring: in storm-prone areas, ground anchors or tie-downs are common, and some local rules require them.

Questions people ask

Can I put a container directly on the ground?

You can on firm, well-drained ground, but it is not ideal. Soil holds moisture against the steel floor frame and can settle unevenly. Blocks, timbers or gravel under the corners keep air moving under it and the doors lined up.

Do I need a concrete slab?

Not for most storage. A container carries its weight on its four corner castings, so solid support under the corners (and ideally along the long sides on a 40ft) is what matters. A slab is great if you already have one or are building something permanent.

How level does it need to be?

As level as you can make it. If it is twisted or badly out of level, the doors can bind or refuse to close. A slight fall toward the door end is fine and helps water run off.
