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.
Use a mallet to lay out the foundation by driving stakes into the ground at each of the four corners. Once installed, tie a string from one stake to the other to create a border around the excavation site.
- 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.
Use a shovel to clear the area within the stakes 4-6 inches deep and level. Some terrain may require greater depth to create a level surface at the bottom of the excavation.
- Tip: Extend the excavation site a minimum of 12 inches past the foundation in all directions.
Line the entire bottom of the excavation with plastic sheeting and add crushed gravel until it fills the entire excavation. Be sure to spread gravel evenly across the entire site, using a 2 x 4 to help level.
- 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.
Place and anchor the wood foundation on the gravel and be sure it is centered and level.
- 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.
