Building a foundation for your structure is vital to ensure its long life. Here’s what we recommend.
CRUSHED STONE
A sturdy foundation of a minimum of 6 inch crushed stone base that is at least 2 feet larger than your building in all directions is recommended. The pad should be as close to existing grade as possible and must be level to allow doors and windows to open properly. The space between the stones will allow moisture to drain directly into the ground, preventing moisture buildup underneath. Crushed stone also lessens splashback when it rains, sparing added moisture to sidewalls and doors.
CONCRETE PAD
Using a concrete pad is recommend for floors of permanent structures. The size of the pad must match the dimensions of your structure exactly to ensure the building is weather tight. The wall sheathing of your building will extend just below the top surface of the concrete.
**We do NOT recommend placing your structure on cinder blocks. There will be some settling of your structure early on, and this may cause your structure to sit unevenly, putting additional stress on overall structure.
**Municipal permitting may be required. For structures over 200 square feet, permitting is typically required. This varies town by town. Please check with your town to comply with local ordinances regarding zoning and permitting.
