Foundation
The Foundation of Perfect Spaces
The first step of a successful home project? Being prepared. Some of our outdoor sheds require concrete or wood foundations for proper assembly, and this quick reference has everything you’ll need to know to start off on the right foot.
Concrete Foundations
Use these standard steps—and helpful tips—to set up your concrete foundation.
- Verify the base measurements of your shed or storage unit. Layout the foundation by using a mallet to drive wooden stakes into the ground at each of the four corners.
- Tip: The concrete foundation should extend a minimum of 3 inches past the base in all directions. Position the stakes to be just outside the length of the foundation and even with the width.
- Tip: Be sure to check local building codes and comply with the designated depth. Where possible, slope the surrounding terrain away from the foundation to allow for improved water drainage.
- Tip: If excavation is 6 inches deep, the top of the stake should be 6 inches up from the bottom surface of the site. For additional stakes, we recommend one every 8 to 10 inches.
- Tip: The plastic sheet will create a vapor barrier that will protect the concrete foundation from moisture damage. If building codes require, or if a heavy-duty application is desired, wire mesh should be placed on the plastic sheeting. Be careful not to pierce the plastic with any sharp edges.
- Tip: Use a trowel to finish the concrete if desired.
Note: Allow the concrete to cure for at least one week before placing any load on it.
Materials Needed
- Shovel
- Metal Rake
- Wheelbarrow
- Wooden Stakes
- Nails
- Mallet
- Measuring Tape
- Crushed Gravel
- Hammer
- Concrete
- Water Supply (garden hose)
- Plywood (pressure treated or lumber suitable for ground contact and cut to the length/width of the excavation)
- Plastic Sheeting
- 2 x 4 Board
- Wire Mesh (recommended for heavy duty applications or if codes require)
Before You Begin
- Check local building codes and required permits.
- Locate buried utility lines prior to any digging and avoid disrupting or damaging any buried utility lines.
Note: Refer to the instruction manual for detailed drawings, overall dimensions, and assembly instructions of the concrete foundation specific to your Suncast Shed model.
Wood Foundations
Use these standard steps—and helpful tips—to set up your wood foundation.
- Assemble the wood foundation on a flat surface and set aside until the next steps are complete.
- Tip: Use a driveway or a garage floor as a flat surface for assembly. Verify the overall size is correct and the foundation is square and level.
- Tip: Extend the excavation site a minimum of 12 inches past the foundation in all directions.
- Tip: Be sure to check with local building codes and comply with the designated depth. Where possible, slope the surrounding terrain away from the foundation to allow for improved water drainage.
- Tip: Leveling the top layer is very important as it helps bear the heavy loads placed on the wood foundation.
- Tip: Rearrange gravel as need be to make sure the foundation is level, and anchor according to local building codes.
Note: You can add a ramp to the entrance side (door side) of the shed foundation to allow for easy entry and exit.
