Should I Put Gravel Under My Shed?

(Wilmington, NC Area Building Guide by BTL Buildings)

Yes—and in most cases, it’s the smartest foundation choice you can make.

If you’re planning to install a shed, one of the most common questions homeowners ask is: should I put gravel under my shed? The short answer is yes, gravel is usually the best option for durability, drainage, and long-term performance.

Why Gravel Under a Shed Is a Good Idea

Gravel creates a stable, well-draining base that protects your shed from moisture-related problems. Unlike bare soil or grass, gravel prevents water from pooling under the shed, which helps avoid rot, mold, rust, and pest issues.

Key benefits of a gravel shed base include:

• Excellent drainage – Water passes through gravel instead of sitting under the floor

• Reduced rot and corrosion – Keeps wooden floors and metal framing dry

• Pest deterrence – Rodents and insects are less likely to nest in gravel

• Improved leveling – Gravel allows precise grading for a flat shed foundation

• Low maintenance – No cracking like concrete, no erosion like bare dirt

What Type of Gravel Should You Use?

The best option is typically crushed stone or crusher run, not pea gravel. Crushed stone locks together when compacted, creating a firm base that won’t shift over time.

Recommended setup:

• 4–6 inches of compacted crushed stone

• Landscape fabric underneath to prevent weeds and soil mixing

• Shed skids or a pressure-treated floor system resting on the gravel

Is Gravel Better Than Concrete?

Depending on your structure’s size, height, and features, you may need:For many residential sheds, yes. Gravel is more affordable, quicker to install, and easier to adjust if the shed ever needs to be moved. Concrete is still a good choice for large shops or vehicle storage, but it costs more and requires more prep and curing time.

When Gravel Might Not Be Enough

Gravel may not be ideal if:

• You’re storing extremely heavy equipment

• The shed will support vehicle traffic

• Local building codes require a permanent foundation

In those cases, concrete footings or a full slab may be required.

Final Answer: Should You Put Gravel Under Your Shed?

Absolutely. For most sheds, a properly installed gravel base is one of the best foundations you can choose. It’s affordable, durable, and protects your investment for years to come.
