Foundation Guide Just-A-Shed is not responsible for site prep. Your city may have specific requirements for shed size, placement or foundation etc., if not, here are some suggestions: (Please feel free to call, place a sales order and we will provide a floor plan and specs upon your request. This provides you with documentation to supply your city if permits are necessary.)
Pressure Treated Skids
Your structure may be placed directly on the ground due to the pressure treated 4x4s we provide. It is important to leave an air space under the floor so as NOT to trap moisture and keep animals away.
Structure may be set on a 4" to 5" deep pad of 3/4" Clean . In order to inhibit weeds and deter moisture, we recommend that the stone perimeter extend 12" beyond your structure perimeter. Do not store mulch or topsoil against the side of your structure. A stone pad can be installed by framing with landscape timbers or 4x4s and then filling flush with stone, or by digging out 4" of soil and installing ground level stone.
Concrete Blocks -Recommended
You can set your structure on concrete blocks, blocking should not extend more than 6" out of the ground. In order to avoid a large step into the shed, we recommend you use 2" or 4" concrete blocks or dig the blocking into the ground near ground level.
Your structure may be set on a concrete pad. When installing your concrete pad, keep your pad 1/4" under your shed size.
Given proper care your structure will exceed its lifespan. Moisture is the enemy. Airflow is the solution. Do not set anything against the exterior of your structure for extended periods of time. Do not plant flowers, shrubs, or trees directly next to your structure.
