If the spot where your shed is going is fairly level (within 12”) the concrete block which we provide will work great as a foundation, and also allows air to pass underneath the shed keeping the floor dry (very important for longevity of building!).
For spots more than 12” out of level, we like to come take a look ourselves or at least see pictures. To level the area out we can add more and/or larger blocks under the shed, build a stone pad, boulder retaining wall or do some light excavation. Give us a call to schedule a free site check if you think your area needs some site preparation.
