It’s a great idea to invest in a shed foundation/shed pad. A gravel foundation will not only keep your shed level for the life of the shed, but will also extend the life of your investment and protect your belongings stored in your shed.

Storage Shed Foundations
- The size of the gravel pad should extend past the footprint of the shed by one foot. You can always go larger if you want a clean base by the entrance or create a sitting area. This means the outside perimeter will be a total of 3 feet larger than the footprint of the shed to leave room for the treated lumber and 1 foot on either side. Most sheds don’t have gutters, so you don’t want roof runoff to go outside of your gravel foundation and create a constant muddy environment.
- Material options for shed retaining walls are pressure treated lumber, precast concrete block, and poured concrete wall. Pressure-treated lumber for a shed retaining wall is the most cost-effective approach, and when installed correctly, will last the life of the shed.
- A concrete pad can be utilized for a shed pad, but exterior concrete is suggested to have a slope of 1/8″ fall per foot to allow water to shed. The most common material for the pad is clean 3/4 gravel that has been washed and compacted.
- Provides proper drainage to prevent standing water
- Creates a capillary break to prevent rot of shed structure
- Prevents settling to keep all doors and windows working properly
- Deters termites and animals from nesting under shed and worse destroying it
