About Our Gravel Shed Foundations In Michigan
The majority of the shed foundations we build in MI are crushed stone foundations (also known as gravel foundations). These gravel pads work well for prefab sheds because they provide strong structural support while helping to drain the area around the shed. While they are the best option for portable and prefab buildings, if you are looking for foundation for a larger structure.

Step 1
Topsoil is removed, and the ground below is compacted.

Step 2
A pressure-treated lumber perimeter is built and staked.

Step 3
A construction-grade stabilization fabric is installed over the dirt.

Step 4
3/4″ clean crushed stone is added (minimum 4″) and compacted.

Reviews From Past Shed Foundations In Michigan
We’ve built shed foundations in Michigan and nearby areas for hundreds of happy clients. Here’s what some of them had to say:
Swing Set Base
Our backyard presented some challenging grades, and they came out to the house to survey the site and put together a very accurate proposal based on our specific conditions. They were also able to work with our schedule and get the base installed in time for our new swing set installation this coming Monday.
Josh, Sam, Jesse, and Steve were all fantastic to work with. Each day, they arrived when they said they would, walked me through the layout for my final approval, and completed the work efficiently and professionally. They were extremely nice people, communicated well throughout the entire process, and clearly took pride in their work.
They took what was essentially an uneven, challenging area of our yard and turned it into the perfect level base for our soon-to-be-installed swing set. The finished product looks great, and I have complete confidence that the swing set will have a solid foundation.
I would absolutely recommend Site Prep to anyone looking for the services they provide. Great company, great communication, and great people. Thank you to Josh, Sam, Jesse, and Steve for a job very well done!
Exceptional Job
We wouldn’t hesitate to hire them again.
Highly recommend!

Permit requirements vary by city and township. Many Michigan municipalities require a permit for sheds over a certain size. We'll help you understand what your local building department requires before we start.
Yes — Michigan's freeze-thaw winters are exactly why we compact a solid stone base and use proper drainage. A well-built gravel or concrete foundation handles frost and keeps your shed level year after year.
Most gravel shed foundations are installed in less than a day. Concrete foundations typically take a few days, including pouring and curing time.
