To prepare the site for your shipping container home, you’ll first need to check if the soil composition can handle the load of your container. Which foundation are you using for your home? There are piers, trench, or raft foundations.

The soil composition will determine if you can set up a container home, and the best foundation. In this post, I’ll tell you how to identify your site soil and what’s the best soil for your container home site.

Each soil holds weight differently weather it sandy, clay, or solid rock, you’ll want to know what’s your soil type is before laying down your plan

Understanding Soil Types

Here are some common soil types that you will encounter in your building site.

Gravel: Gravel offers excellent drainage and is easy to dig out to the depth needed for your foundation. If your site contains gravel, then the best foundation is a trench footing.

Rock: While you might think rocky soil is bad, it’s not. It’s a bit challenging to work with, but if you strip the surface soil and level the pad in the process, then you are prepared.

Rocks have a high-load capacity that can support your foundation. If you still need support, then a concrete pier is an excellent option.

Sandy Soil: Sandy soil composes of both gravel and rocks mixed in. If the weight is poured evenly, then it’s high load-bearing and can hold your container home and foundation.

As a result, the raft foundation is your best bet. Also, don’t over dig the foundation since it can put too much weight on the softer soil.

Clay: This is the worst soil to have in your site however, if you encounter this you should get a Geotech report since this will help you know the clay depth.

Clay holds water, so you must dig past the clay and backfill it with suitable soil.

How to Check Your Soil Type?

The best way to check your soil type is to hire a Geotech engineer. A Geotech will tell you the composition of your soil, if there are any shaky soil, and help you understand your soil much better.

The soil tested by the Geotech and will describe the soil type 20ft and will help you understand the load-bearing capacity. Further, it will let you know if you have to level your site and to help fix the challenges of the site.

Also, if you are building within the city limits, then your local authority will have a soil profile of the area. However, if they’re no records of your soil profile, or you are building away from city limits then you must add this to your budget.

To get your site ready for your container home, you must know and understand your site soil profile. This profile will tell you if you have to backfill, dig deeper as well as the best foundation for your home.
