Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 38x38 feet, 1,444 sq ft, about 37.4 tons at 6 inches. It keeps mud away from the doors and protects the post bases.
Build it in layers
Strip topsoil, level and compact the subgrade, then spread stone in lifts of about 3 to 4 inches, compacting each. A coarser base topped with a finer, packable stone often makes the most solid floor.
Ordering and delivery
Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Round up by about 10 percent for compaction and uneven ground.
