How To Put Shipping Containers On Blocks

Guide to Setting Shipping Containers on Blocks

Setting a shipping container on blocks can help improve drainage, airflow, stability, and long-term usability. Whether you are using a container for storage, equipment, inventory, jobsite materials, or business operations, the way the container is placed matters. A container that sits unevenly can be harder to open, more likely to shift, and more exposed to standing water or ground moisture.

This guide explains common block options, how to prepare the site, and what to consider before placing a container. For heavy containers, permanent installations, soft soil, sloped sites, or areas with frost, flooding, or strict building rules, always check local requirements and consult a qualified contractor, engineer, or building authority before installation.

Key Takeaways

• Concrete blocks, concrete piers, and precast concrete footings are common options for supporting shipping containers when the site is properly prepared.
• Wood blocking can work for temporary placement, but it may require more maintenance because wood can rot, shift, or attract pests over time.
• Steel supports and engineered piers can provide strong, long-lasting support, but they should be selected and installed based on site conditions and load requirements.
• Level ground, drainage, and proper block placement help keep container doors aligned and reduce the risk of settling.
• Conexwest can help with container delivery, placement planning, and container options for storage, business, and jobsite use.

Why Set a Shipping Container on Blocks?

A shipping container is designed to carry weight through its corner castings and structural frame. When placing a container on a site, the goal is to support it evenly, keep it level, and protect it from ground moisture. Blocks or footings can help raise the container off the ground and create a more stable base.

Blocking can be especially helpful when the container will sit on dirt, gravel, compacted soil, or another surface where drainage and settling need to be considered. It can also make it easier to keep the doors operating properly, since uneven placement can cause the container frame to twist slightly and make the doors harder to open or close.

Types of Blocks Suitable for Shipping Containers

1. Concrete Blocks or Concrete Piers: Concrete is commonly used because it is durable, widely available, and resistant to rot. For container placement, solid concrete supports or properly installed piers are generally preferred over lightweight or hollow blocks.
2. Cinder Blocks or CMU Blocks: Standard hollow cinder blocks are not always suitable for heavy container loads unless they are properly oriented, reinforced, filled, or approved for the application. If using masonry blocks, confirm load capacity and installation requirements with a qualified professional.
3. Wooden Blocks or Timbers: Heavy timber blocks or railroad ties can be used for temporary support, especially when quick placement is needed. However, wood can rot, compress, shift, or attract pests, so it is usually better for short-term or temporary use.
4. Steel Supports or Piers: Steel supports can provide strong and adjustable support for containers, especially on uneven sites. They are often more expensive and should be selected based on the weight, soil conditions, and intended use.
5. Precast Concrete Footings: Precast footings can provide a strong, level base and help distribute weight at specific points beneath the container. They are often used when a more permanent or stable foundation is needed.

10 Steps to Put Shipping Containers on Blocks

1. Choose the Right Location

Select a flat, accessible area with enough space for the delivery truck to maneuver and place the container. Avoid soft ground, steep slopes, drainage paths, overhead obstructions, and areas with underground utilities. If the container will be used for frequent access, make sure the doors face a practical loading direction.

2. Prepare the Ground

Clear debris, vegetation, rocks, and loose material from the placement area. The ground should be firm, dry, and as level as possible. If the area is uneven, it may need to be graded with equipment such as a skid steer, bobcat, or excavator.

If the ground is soft or poorly drained, consider adding a compacted gravel base to improve drainage and reduce settling. Good site preparation helps prevent the container from shifting, sinking, or becoming difficult to operate.

3. Mark Placement for Blocks

Use stakes, marking paint, or string lines to outline where the container will sit. Blocks are commonly placed under the container corners, and additional support points may be used along the length of the container depending on the site, container size, load, and intended use.

For containers that will hold heavy equipment, dense inventory, vehicles, or modified interiors, consider having the foundation layout reviewed by a qualified professional.

4. Excavate for Blocks

Dig shallow holes or trenches where each block or footing will be placed. The goal is to create a stable base and reduce movement. In some cases, supports may be set slightly below grade with gravel underneath to improve stability and drainage.

5. Add a Gravel Base

Add a few inches of compacted gravel below each support point. Gravel helps distribute weight, improve drainage, and reduce moisture buildup around the supports. This step is especially useful on dirt or soil surfaces.

6. Position the Blocks

Place the blocks, concrete piers, timbers, or footings in the prepared locations. Make sure they are aligned with the structural support points of the container and positioned to keep the container level. Supports should be stable, flat, and appropriate for the expected load.

7. Check Level

Use a spirit level, laser level, or transit level to check that the supports are even before the container is placed. Adjust by adding or removing gravel, compacting the base, or using appropriate shims where needed.

8. Secure the Base

Once the supports are positioned and leveled, compact the gravel and confirm that each support is stable. Blocks should not wobble, shift, or sit on loose soil. A stable base helps reduce movement during delivery and after the container is loaded.

9. Lift and Position the Container

When the site is ready, use appropriate delivery or lifting equipment to position the container. Depending on the location and container size, this may involve a tilt-bed truck, side-lifter, crane, forklift, or other equipment. Learn more about container handling in our guide on how to move shipping containers without heavy equipment.

The container should be lowered carefully onto the prepared supports. The corners and frame should sit evenly so the container remains level and the doors operate correctly.

10. Make Final Adjustments

After placement, check the container level again. Open and close the doors to confirm that they operate smoothly. If the doors bind or the frame appears uneven, the support points may need adjustment. Do not force misaligned doors; uneven support can cause operational issues over time.

Why Put Shipping Containers on Blocks?

Preparing a solid foundation helps support the container, protect it from moisture, and keep the doors operating properly.

1. Improved Stability: Elevating a container on properly placed supports can help reduce shifting caused by uneven ground, settling, or poor drainage.
2. Better Drainage: Raising the container off the ground helps reduce direct contact with standing water, mud, and ground moisture.
3. Easier Door Operation: A level container frame helps keep the doors aligned. If a container twists or settles unevenly, the doors may become difficult to open or close.
4. Improved Airflow: Elevation can allow airflow beneath the container, which may help reduce moisture buildup under the floor.
5. Reduced Pest Access: Keeping the container off the ground can make it easier to inspect around the base and reduce potential nesting areas.

How Conexwest Can Help With Container Delivery and Placement

Container Blocking Safety Tips

Blocking a shipping container is not just about lifting it off the ground. The container must be supported in a way that matches the site, load, and intended use. Before placing a container on blocks, keep these safety tips in mind:

• Do not use unstable, cracked, or undersized blocks.
• Do not place heavy containers on loose soil without proper base preparation.
• Do not rely on hollow blocks for heavy loads unless properly filled, reinforced, and approved for the application.
• Do not block airflow around the container if moisture is a concern.
• Do not place supports where they interfere with door operation or delivery equipment.
• Do not assume temporary blocking is suitable for permanent installation.
• Check the container after placement and after heavy rain, freeze-thaw cycles, or major loading changes.

Frequently Asked Questions (FAQs)

Do I need a permit to place a shipping container?

Permit requirements vary by location, property type, intended use, and how long the container will remain on-site. Temporary storage on commercial property may be treated differently than a permanent installation, office conversion, or container used for habitation.

Check with your local building department, zoning office, homeowners association, landlord, or property manager before placing a container. Local rules may address setbacks, screening, foundations, stormwater, fire access, and permit requirements.

What is the best block type for long-term use?

For long-term use, concrete piers, precast concrete footings, or engineered supports are often preferred because they are durable and resistant to rot. The best option depends on soil conditions, container size, load, climate, and local building requirements.

Can I use cinder blocks under a shipping container?

Standard hollow cinder blocks are not always suitable for supporting heavy container loads unless they are properly installed, reinforced, filled, or approved for the application. Solid concrete supports or engineered footings are usually a safer choice for heavy or long-term placement.

How high should I raise my shipping container off the ground?

The right height depends on drainage, soil conditions, climate, access needs, and local requirements. Many storage containers are raised enough to promote airflow and reduce ground moisture, while flood-prone or wet areas may require higher elevation and a more engineered foundation.

What should I do if my shipping container doors are difficult to open after placement?

Difficult doors may mean the container is not level or has settled unevenly. Check all support points and confirm the container frame is level. Adjustments may require adding proper shims, re-leveling the supports, or lifting the container safely with appropriate equipment.

How do I prepare my site for container delivery from Conexwest?

1. Choose firm, dry ground: The area should be level and stable, ideally on pavement, compacted gravel, or hard dirt.
2. Confirm clearance: Make sure there is enough space for the delivery truck to maneuver and place the container.
3. Remove obstacles: Clear trees, low branches, fences, parked vehicles, debris, and overhead obstructions that could interfere with delivery.
4. Plan container orientation: Decide which direction the doors should face before delivery.
5. Prepare support points: If the container will be placed on blocks, make sure the supports are level, stable, and ready before the truck arrives.
