Does the building need to sit on gravel or concrete?
The only requirement is a level location. Our buildings are designed to rest directly on their skids. In order to level use a jack to raise the building until it is level, then we block underneath it with ground contact rated treated wood blocks. If you would like to have your building on concrete blocks, we can provide that service. We only require that you provide the blocks. The rule of thumb for figuring blocks is one block for every 4′ of skid length on the flat ground. A typical 10×16 is blocked at 6 to 8 points, one block on each end of the skid and one or two blocks in the middle of each skid. If the area where the building is to be placed is 2′ or more out of level, we highly recommend buying concrete blocks. We recommend 4″ thick, solid cap blocks. Thinner blocks tend to crack, and larger blocks cause the building to be higher above the ground and more difficult to access. It is not advisable to place the blocks before the driver delivers the building.
