Shed with concrete floor/base

by Stephen

I intend to build a 12' by 8' larch ship lap shed with a concrete floor. What size of concrete base should I build and how do I attach the shed to the base to ensure it is waterproof.

Place threaded rod into the concrete just before final finishing.

Use galvanized steel fasteners; either 1/2-13 or 9/16-12 should be fine.

Ensure the the rod is sunk a minimum of 4 inches into the concrete and is exposed above floor level approximately 5 inches. This will provide about 1-inch of thread above the wall bottom plate if two 2 x 4 's are used.

After the walls are standing, use a flat washer and split lock washer under the nut. Be sure to layout the rod locations so that they are in the center of the bottom plate's width and fall between between the wall studs.

Place a rod between every other stud space and at each corner.
