What Foundations Should my Storage Unit Have?

  • Care & Maintenance
18th January 2021

One of the major advantages of cargo units is that they are mobile and can easily be moved to a new location. If you plan on moving your unit regularly, then it is unlikely that you will need to create a new foundation each time. You simply need to ensure that your box is placed on a sturdy, level surface. Nevertheless, there are occasions when your unit will require a foundation, i.e., if you are constructing a pop-up home. Below, we are going to discuss when a foundation is required and compare the different foundation types.

When is a foundation required?

As mentioned, if you plan on keeping your unit, then it’s unlikely that you will need a foundation. That being said, you must ensure that your unit is placed on a flat, stable surface. If the ground is not level and sturdy, then you will need to add a foundation before placing your unit on it.  If you plan on keeping the unit at your site long-term, i.e., for longer than one month, then you should also place it on a foundation. Finally, you should also consider creating a foundation if your unit starts to look unlevel.

What foundation can I use?

The main purpose of a foundation is to keep your unit stable and to protect it from extreme weather such as heavy rain. Generally speaking, you have four options when it comes to choosing a foundation for your unit. We are going to discuss these in more detail below:

1. Slab foundations

Slab foundations are made from concrete and offer a strong base for your unit. This type of foundation is typically used when the ground is especially soft, as it offers the most support. Keep in mind that you will need to hire a specialist team to lay a slab foundation. This type of foundation is the most labour-intensive and thus has a higher cost.

2. Pier foundations

A pier foundation is usually created by embedding concrete blocks into the ground at each corner of the unit. Additional blocks are sometimes added in the middle to provide extra support for a large or heavy unit. In most cases, a pier foundation can be done DIY without the help of specialist builders.

3. Strip foundations

Strip foundations are similar to slab foundations, but they are cheaper and less labour-intensive. To create a strip foundation, you place concrete blocks around the outside of where the unit will be placed. Digging is required, but you may be able to lay a strip foundation without hiring professionals.

4. Pile foundations

Pile foundations are the least commonly used, as they are the most expensive type of foundation and require specialist tools and workers. To create a pile foundation, solid steel tubes are inserted deep into the ground until they are stable. These poles are then filled with concrete before the unit is placed on top. Pile foundations are only used when the land is extremely unstable and cannot support the unit.

How can I find out more?

In many cases, these units do not require a specialist foundation. However, there are some circumstances when your purchase will need a foundation, i.e. if you plan on keeping it as a permanent fixture at your site long-term. In this situation, choosing the right foundation for your unit is essential to ensure that it is stable and protected from damage.
