Wood Foundations

Assembly Steps

  1. Assemble the wood foundation on a flat surface. Set the foundation 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.

  2. Lay out the foundation by using a mallet to drive 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: Excavation should extend a minimum of 12″ past foundation in all directions.

  3. Clear the area within the stakes using a shovel. Be sure to excavate the entire area 4-6 inches deep and level the site. Some terrain may require more depth to create a level surface at the bottom of the excavation.

    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.

  4. Line the entire bottom of the excavation with plastic sheeting, and add crushed gravel until it fills the entire excavation depth. Be sure to spread it evenly across the entire site.

    Tip: Level the top layer of the gravel. This is very important, as the wood foundation will be placed on top of the gravel, and the gravel will aid in bearing any heavy loads.

  5. Place, and anchor the assembled wood foundation on the gravel. Be sure that it is centered on the gravel and level.

    Tip: If needed, move the gravel around to level the wood foundation. Anchor according to local building codes.

  6. If desired, a ramp may be added to the entrance side (door side) of the shed foundation to allow for easy entry/exit of the shed or storage unit.
