Getting the ground right is one of the most important parts of buying a shipping container. The container itself is strong, but it still needs to sit level and stable if you want the doors to work properly and the unit to last well.
The ground does not always have to be perfect, but it does need to be suitable.
Firm and level is best
The ideal surface for a shipping container is firm, level and well drained. Concrete, tarmac, compacted stone, paving slabs or a prepared hardstanding area can all work well.
The key point is that the container should not twist, sink or sit in standing water. If it settles unevenly, the doors may become harder to open and close. Over time, poor drainage can also make maintenance more difficult.
Containers carry weight through the corners
Shipping containers are designed to carry weight through their corner posts. This means the four corners should be properly supported. In many cases, customers use concrete pads, railway sleepers, paving slabs or similar supports under the corners.
The supports need to be stable and suitable for the load. If they move or sink, the container may no longer sit level.
Can a container go on grass?
A container can sometimes be placed on grass, but it is not always the best choice. Grass can become soft, uneven and wet, especially during winter or after heavy rain. If the container sinks at one corner, door operation can be affected.
If grass is the only available option, it is worth adding proper supports under the corners and making sure the area drains as well as possible.
Think about water
Water should be able to drain away from the container. Avoid low spots where rainwater collects. Try not to place the container directly where water runs off a roof or across a yard.
Keeping the base dry helps protect the underside and makes access safer for people using the container.
Allow space around the doors
Ground preparation is not only about the container footprint. You also need enough room for the doors to open fully and for people to load and unload safely.
If you plan to use a forklift, pallet truck or machinery near the container, allow enough hardstanding in front of the doors. A container tucked into a tight corner may fit physically but still be awkward to use.
Delivery vehicle access
The delivery lorry needs safe access to the site and final position. Narrow gates, tight turns, low branches, overhead cables, parked vehicles, soft ground and steep slopes can all create problems.
Before delivery, take photos and measurements if you are unsure. It is better to check access in advance than leave it to chance on the day.
Preparing for delivery day
Clear the area before the lorry arrives. Move vehicles, materials, bins, branches and anything else that may obstruct access. Mark the final position if needed, and make sure someone on site knows exactly where the container is going.
If the site has any restrictions, tell the supplier early. A few clear photos can save a lot of time.
FAQs
Does a container need a concrete base?
Not always, but concrete or hardstanding is ideal. Firm, level and well-drained ground is the main requirement.
Can I put a container on sleepers?
Sleepers may be suitable if they are stable, level and properly positioned under the load points.
Why do container doors become hard to open?
Often because the container is not sitting level or has twisted due to poor ground support.
How much space do I need in front of the doors?
You need enough room for the doors to open fully and for safe loading and unloading.
Can delivery be checked beforehand?
Yes, photos, videos and measurements can help assess access and placement.
