About Our Gravel Shed Foundations In New Jersey
Our gravel (crushed stone) shed bases are our most popular form of shed site prep in New Jersey. A gravel shed foundation is best for prefab sheds and other buildings with pre-built wooden floors. We use compacted “clean” stone, which provides a firm base for your shed while allowing water to drain through.

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.

Gravel Shed Foundation
Excellent work. The team of Jay, Stephen and Jesus were the best! Thank you!!!
Great Job
Ritchie and Stephen did a great job.
10 stars! Dog Play Area Turf Yard
We had Site Prep install a clean, cozy, dedicated, healthy, protected, safe, and secure space for our Golden Retriever puppy (Aspen) to ensure her comfort in any weather: Dog Play Area Turf Yard.
Turf areas provide several benefits for pets: reduced exposure to harmful chemicals, allergens, and parasites found in natural grass. Promotes better hygiene and cleanliness by preventing mud, dirt, and pests from getting into the house. Enhances physical activity and mental stimulation of pets by providing a safe space for them to play and exercise … just to name a few of the advantages.
The crew is a powerhouse of talent! Not only do they have great work ethic, are polite, courteous, detail-oriented, focused, *hardworking*, and meticulous … Site Prep is undeniably committed to excellence.
Start to finish during the entire process, working with Site Prep was an outstanding experience. From visiting our home to review the work, continued communications throughout the job, preparing the area, excavating and installing the perimeter, adding the stabilization fabric and crushed stone/gravel, to adding the material and final turf product. I repeat: 10 stars! Highly recommend.
Ben, Dave, Sam, AJ, Alex, Richie, Ed, Tim: thank you for an outstanding job and for a pawsitively amazing dog play area for our Golden girl Aspen!
Wow! Amazing work
They had to deal with a lot of rocks, roots, and about 19” off leveled area for a 14×22 site. The finished product is perfect and ready for a new shed!

FAQs
Yes, those terms can be used interchangeably. Our pads are built with crushed stone but are often referred to as “gravel” shed foundations, so we often refer to them that way as well.
Yes, there are. However, we recommend gravel shed foundations due to their combination of affordability, durability, and ease of installation.
In some cases, local ordinances may require that gravel shed foundations be modified with frost-proof footings such as shed foundation piers. For even more foundation types, check out our comparison of the top 13 shed foundation options here.
Not technically. Gravel actually refers to round river stone, which is not suitable for a foundation. Our shed foundations are built with crushed stone. Crushed stone is ideal for a shed foundation because its uneven shape allows it to be tightly compacted into a firm base while still allowing water to drain away from the shed.
However, many people refer to crushed stone as “gravel”, so we often do too!
Absolutely! There are two primary ways of building a shed foundation on uneven ground:
- Building up – This involves building a retaining wall of pressure-treated lumber and bringing the shed foundation up to level. You can see an example of a built-up shed foundation here.
- Digging out – This involves excavating into the slope and then building a retaining wall of pressure-treated lumber to protect the shed. You can see an example of a dug-out shed foundation here.
- You can also use a combination of building up and digging out to place the foundation at a specific height. This is especially useful if the doors will be on the side of the shed. You can see an example of a combination shed foundation here.
Alternatively, some types of sheds and other buildings can be supported with concrete piers built up from a slope, such as in this example.
We don’t recommend installing your shed on blocks as this can create problems for your building down the road. Potential issues include:
- Floor joists are supported unevenly.
- Possible settling over time.
- Binding windows and doors.
- Space for critters to get under the shed.
In fact, many shed companies now require that their buildings be placed on a gravel shed foundation in order for their warranty to stand.
This article explains why shed foundation blocks are a bad idea in more detail.
Yes, gravel tends to be cheaper than concrete.
