How to Prepare The Site for Your New Shed
A gravel pad is a very good option for a shed pad since it provides a solid, porous foundation for your shed. The gravel pad can either be above ground or be dug out at ground level. We recommend 3 to 4” of road base or #57/67 crushed rock from Martin Marietta for your pad. Your gravel pad should be wider and longer than your building to allow for a skirt around it if you choose to.
A concrete pad is a long-term, quality option for a shed foundation. While it may be overkill in many cases, it certainly provides a stable, solid foundation. If you have a contractor install a pad, just ensure that it is square and level.
Setting your building on piers is a good option if you have a sloped site.Typically when the concrete is poured for the piers a metal bracket is installed to anchor the building to the pier.
