If you have recently purchased a storage container, you may wonder if you should set it on a foundation. In a nutshell, yes, you should. That’s because the ground tends to moves a bit over time, rising, sliding and even sinking. This is why you need a stable foundation to keep the home or other structure on level footing – just like you would a traditional new construction house.

Whether you require a pier foundation or a pile foundation, your shipping container home needs a strong foundation which will act as a solid platform. It doesn’t matter what the use will be; if you fail to secure the foundation properly at this time, the container could separate or split later on. Your container will then become unsafe or unstable, which can compromise your safety as well as the contents of the unit.

You also need to consider a uniform foundation due to the fact that the ground underneath the container is made up of many materials, such as clay and hard rock. Inconsistencies can result, leading to doors that are difficult if not impossible to open.

When you have a solid foundation, you are assured of proper distribution of weight, while at the same time preventing moisture and corrosion infiltration.

Wondering if there are times when you don’t need a foundation? You don’t need one when the shipping container location is only temporary and you plan to move it in a matter of weeks or months. This often applies to construction companies who tend to move from site to site often.

What Kinds of Foundations Are There?

You can choose from a variety of foundation types, such as:

  • Concrete Slab: The most common and the easiest, pouring a concrete slab is not only convenient, it’s cost effective as well and not as labor intensive as other options. Concrete also withstands the elements, so if you can, go with professional concrete pouring.
  • Concrete Footings: These are positioned at various intervals to give more support for the container, with brackets holding cross beams or crosses.
  • Pile Foundations: These are circular metal or wood beams that are placed into the earth around sand or water until bedrock is reached. They are most common at marinas, and can provide support for the construction of a deck-like structure to support the weight of a container on top.  

Regardless of the foundation type you decide on, the purpose is to keep it stable. You will get a longer long life span from the unit, giving you peace of mind knowing that your unit’s safety and structural integrity is well taken care of.
