DIY Concrete Foundation for a Garage or Shed (With Curb Wall!)

This is a diy concrete foundation we did for a garage. The garage slab was 16' x 24'. You could use this slab foundation for a shed also.
We added a two foot high curb wall to the foundation slab so the exterior could be back filled higher than the slab height.
