About Our Gravel Shed Foundations in Maryland
Our gravel shed foundations (also known as crushed stone pads) are the most common type of shed foundation we build in Maryland. A crushed stone shed base is ideal for any prefab shed or garage that includes a wooden floor. We use “clean” stone for maximum drainage and compact it so that your building is properly supported.

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.

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.
